The world's water consumption rate is doubling every 20 years — twice as fast as the population growth rate. By 2025, water demand will exceed supply by 56%.
The critical need for water to sustain all aspects of human activity has driven us to inhabit floodplains and deltas close to rivers. Today, 82% of the global population lives in these areas and is exposed to a high risk of flooding.
We constantly strive to develop a robust understanding of the physical water environment as a precursor to any analyses influencing decision-making. Applying state-of-the-art modelling technologies and analytics ensures that we achieve this. We work closely with our clients and stakeholders to appreciate the water management issues that may affect their project outcomes. In so doing, we develop solutions that are appropriate, cost-effective and environmentally responsible.

Development of new modelling tools for national marine water planning based on ECO Lab
Our ecological modelling software, ECO Lab, will be used in a new project with the aim to develop an advanced set of dynamic modelling tools, which will be the official tools for marine water planning in Denmark in the coming years.
The project is initiated as a collaboration between DHI and Danish Centre for Environment and Energy (DCE). The project will develop and apply ecosystem models by using our MIKE by DHI software, ECO Lab, and addressing the governing coastal processes and ecosystem services such as sediment processes, sea grass, algal growth and oxygen depletion.

Enabling optimised construction of the London Array offshore wind farm
Our real-time system provided accurate forecasts of Metocean conditions on a detailed spatial and temporal scale for the world’s largest wind farm – London Array. This enabled London Array Ltd. – the consortium behind the wind farm – to optimise the construction of the offshore wind farm. The result: minimised delays and ensured safety for those working on the project.
Situated in the outer Thames Estuary, is the world’s largest offshore wind farm: the 1 GW London Array. Weather conditions in this area are often challenging, which made construction and installation of the wind farm difficult. As such, high-quality and reliable Metocean data was vital for the successful planning and installation of London Array’s foundations and turbines.
London Array Ltd. needed to be able to predict available weather windows. We used our 30 years of experience in Metocean forecasting for this purpose. This ensured that the London Array project benefitted from the most up-to-date and advanced technologies, combined with local experience of forecasting techniques and equipment.
By assisting London Array Ltd. with forecasting Metocean conditions, our system helped keep delays to a minimum during the construction phase. In addition, our system also enabled London Array Ltd. to efficiently plan maintenance work during the operations phase.

CARM wins Australia’s national Environmental Engineering Excellence Award
On 20 November 2013, the Institution of Engineers Australia awarded the Computer Aided River Management (CARM) project the Environmental Engineering Excellence Award. This prestigious award honours the top achievements in environmental engineering and the sustainable use of natural resources. The award was received by our client State Water Corporation of New South Wales.
Our software is the backbone of CARM – a Decision Support System (DSS) based on MIKE CUSTOMISED by DHI components. CARM gives State Water Corporation an insight into the current and forecasted state of the Murrumbidgee River. It utilises a suite of MIKE by DHI models to reproduce key catchment and river processes for the entire 1,600 km river system, and combines them with real-time measurements. This allows river operators to combine dam releases with natural tributary inflows to deliver the right amount of water when and where it is needed.

Transforming abandoned mining pits into new lake districts
The mining industry can have severe consequences for regions and the surrounding landscape, impacting vegetation and wildlife negatively when mining production is abandoned. Rehabilitating old mining areas can be a highly difficult challenge and few succeed.
However, with the right strategies and tools available, abandoned mining pits can be turned from lifeless landscapes into prosperous manmade lake districts. This is what has been done in Eastern Germany, where DHI-WASY was able to provide accurate analysis and the right strategies for creating a new lake. For this purpose, integrated groundwater modelling was essential using among other products FEFLOW 6.1 and MIKE 11.

The latest MIKE by DHI NetWork newsletter (July 2012) has now been published. Selected highlights from this, and other recent, newsletters are presented below: -
Application Examples from Around the World
- MIKE 3 used for innovative project at the Maspalomas desalination plant in Spain: A new and innovative project in the Canary Islands in Spain has resulted in the successful development of an effective method for reducing the environmental impact of brine discharges on marine ecosystems. In order to mitigate the impact of large spreading brine discharges from desalination plants, which affect the benthic communities at the sea bottom, a study was made at the Maspalomas desalination plant in Gran Canaria. The feasibility study focused on applying Venturi effect ejectors in brine discharges versus conventional diffusers as a mechanism to improve the dilution processes at acceptable costs for new and existing plants. DHI contributed by developing and applying numerical models for the study of the brine dispersion, including a MIKE 3 model to simulate the brine plume far field, which was calibrated using measurements from several monitoring surveys. Read more here.
- Oil dispersion in Guanabara Bay in Rio de Janeiro, Brazil: DHI Brazil was recently requested to perform an oil dispersion modelling to support the development of an emergency plan for a port terminal in Guanabara Bay in Rio de Janeiro. As part of the emergency plan, an analysis of the effects of oil pollution incidents on the safety of life and the environment was performed, taking into account the sensitivity of the areas likely to be affected and the possibility of occurrence. The determination of these exposed areas was conducted through mathematical modelling. Thus, the hydrodynamic and oil dispersion modules of the modelling system MIKE by DHI were used to simulate different scenarios of accidental oil spills within the bay. Read more here.
- Protection of cruise terminal in Jamaica with MIKE 21: The Falmouth Terminal on the north shore of Jamaica is used by thousands of cruise line passengers each year, but the extreme hurricane events that occur in the region each year pose a flood risk of the terminal buildings. DHI performed comprehensive research and modelling to evaluate the best way to protect the cruise terminal buildings, even during extreme hurricane events in a highly complex bathymetric setting. For this purpose MIKE 21 PMS (Parabolic mild-slope) and MIKE 21 BW (Boussinesq Wave) was used to reproduce the energy dissipation due to wave breaking as well as the wave refraction and wave diffraction. Read more here.
- Uncertainty analysis to improve design criteria of wastewater treatment plants (WWTP): The Umbrella-DOUT initiative is a net of seven interconnected projects that aim at analysing how uncertainty is being tackled in wastewater treatment plant (WWTP) design. Design guidelines (Metcalf & Eddy, ATV, Grady, etc.) and safety factors are generally used to develop designs that ensure some effluent requirements (average ammonium below 3 mg/l; total nitrogen below 18 mg/l, etc.). Read more here.
- Researching the Grand-Lieu Lake in France with MIKE 21: The Science University of Nantes is using MIKE 21 software for ecosystems research of the Grand-Lieu Lake in France. The natural area of the Grand-Lieu Lake is well protected, but suffers an alarming evolution including phenomena such as fast erosion of the macrophytes belt, significantly decreasing biodiversity, early blooming of cyanobacteria phytoplankton, and negative sedimentary balance. Read more here.
- Modelling the Tohoku tsunami in Japan: One year has now passed since the tragic tsunami of 11 March 2011. Together with the Danish Authorities and especially the Royal Danish Embassy in Japan, DHI has provided assistance to Higashi Matsushima city, which is one of the hardest affected communities along the coastline of the Tohoku region. At Higashi Matsushima, the tsunami wave reached more than 10 m, propagated as far as 5 km inland, claiming at least 1039 lives of a population of 42,000, and destroyed more than 60 % of the city. Read more here.
- Modelling the 11 April mini-tsunami in the Indian Ocean: In the afternoon of 11 April 2012, an earthquake occurred 500 km off the north-western coast of Sumatra, near the region where the devastating Indian Ocean tsunami was generated in 2004. On 11 April, the earthquake was felt strongly in Sumatra, but also in Malaysia, Singapore, and even in places like Bangladesh and the Maldives. The level of awareness was high, and shortly after the earthquake a tsunami warning was issued for the entire Indian Ocean due to a well-functioning tsunami watch, which was set into effect only seven minutes after the earthquake. Fortunately, a large tsunami did not materialise. Read more here.

Previews of MIKE by DHI 2012 Release
As detailed in the February 2012 issue of our newsletter, we would like to present some previews of the upcoming MIKE by DHI software package 2012, which is scheduled to be released this September. The release will contain various new and exciting features, which we hope will improve your experience when using the software products, both with regard to usability, productivity, and enhanced applications.
FEFLOW 6.1: Selective Mesh Smoothing for Finite-Element Meshes
Now you can look forward to improved model quality and even faster modelling with the upcoming FEFLOW 6.1!
Smoothing a finite-element mesh can significantly improve the quality of a mesh that, in some cases, might be unsatisfactory after the generation process due to the presence of too many triangles with acute angles. Within groundwater modelling it is essential to keep hydraulic structures, e.g. well locations and other structures defined by the user at their original position. In FEFLOW 6.0, only a global mesh-smoothing option was available, which does not provide the means to exclude selected mesh nodes from shifting positions during the smoothing process.
With the upcoming version of FEFLOW 6.1, we have improved the smoothing functionality significantly: Smoothing can now be applied in selected areas of the finite-element mesh, only allowing maintaining the original positions of boundary conditions etc. as defined by the modeller.
WEST: How to convert plant layouts and experiments from older WEST versions?
The new WEST3 conversion tool allows for converting plant layouts and experiments from WEST 3.7.6 to WEST 2011. It will be available with the release 2012 and via download at the MIKE by DHI website.
Layouts that are based on the standard WEST model library are supported without further ado. During conversion, the user can choose whether to adopt the new WEST 2011 icons, or the old WEST 3.7.6 icons for the converted layout. The conversion tool does not require WEST 3.7.6 to be installed. However, it does require a valid WEST 2011 license.
Please do not hesitate to contact MIKE by DHI support if you have any questions related to WEST, or how to get the most out of the software.
MIKE URBAN: Storm Water Tools
With the release of MIKE URBAN 2012, the Storm Water Tools will be fully implemented into MIKE URBAN using either MOUSE or SWMM as simulation engine.
The MIKE URBAN Storm Water Tools focus on building the Storm Water model within a 1D framework. The tools supplement the standard MIKE URBAN installation by empowering the user with the ability to carry out:

Application Examples
The newsletter can be viewed online here.
- Protecting clean drinking water from Lake Ontario, Canada:
Most of the North American region and in particular Ontario’s 13 million residents are highly dependent on clean drinking water from one of the Great Lakes. Thus, as contamination of the lakes could have severe consequences for many communities, a study was initiated to investigate potential threats to the water quality of Lake Ontario.
As a part of Ontario’s Source Water Protection program, a group called the Lake Ontario Collaborative was formed to study the potential threats to the drinking water. They have investigated potential impacts that activities on land, such as potential spills from surrounding waste water treatment plants, nuclear power plants, petroleum pipelines, and industrial facilities could have on the contamination of the water quality at the areas of intakes. For this purpose, they used an events-based approach, where potential spills were modelled by calculating the hydrodynamics as well as different aspects of the water quality. By using a full three dimensional illustration of water motion, including thermodynamics, it was possible to make accurate simulations and predictions of water currents in the lake and simulate the potential damage of a spill scenario.
As a result, they were able to develop intake protection zones. The zones were used to help raise awareness of the potential environmental and health risks that potential spills could entail as well as guide the preparation of emergency response planning in the event of a spill in the future.

Previews of MIKE by DHI 2012 Release
In the coming issues of our MIKE by DHI NetWork newsletter, we would like to disclose some previews of the new MIKE by DHI software package 2012, which is scheduled to be released this summer. The release will contain various new and exciting features, which we hope will improve your experience when using the software products, both with regard to usability, productivity, and enhanced applications.
Improvements for MIKE Animator in development
In 2012, MIKE Animator is to be replaced with MIKE Animator Plus. Compared to the existing MIKE Animator the new MIKE Animator Plus will offer an extended set of features. The most important of these new scheduled features are be:
The above example shows a MIKE 3 Flexible Mesh result file with two vertical and one horizontal slice. This new feature will allow the user to get a much better overview of large 3-dimensional result files than ever before.
Littoral Processes FM: Re-design and development of LITPACK
In version 2011, the first step of the re-design of LITPACK was released, including the modules LITSTP and LITDRIFT. In the scheduled release for 2012, this re-design continues and includes the functionalities included in LITLINE.
The redesign constitutes an important milestone in the development of the system with regard to improved usability and integration into the coupled FM modelling system. The most obvious changes include the new user interface, which have the same look and feel as the rest of the MIKE Zero based products, including MIKE 21. Also the file formats have been changed. There will be one common set-up (pfs) file for all LITPACK-modules and the consequent use of standardised dfs-file formats has made it possible to introduce a higher flexibility when defining input- and output data. In this sense, one of the improvements included in the release in 2012 is the ability to work with an unlimited number of wave climates along the coastline, defined in a dfs1-file. Furthermore, all data in Littoral Processes FM will be geo-referenced, something which also makes it possible to display data in a graphic, geo-referenced view.
The above example shows the geographic positioning of groyne structures, with a mesh file shown as background.
Behind the scenes of MIKE URBAN 2012
Also MIKE URBAN users will notice improvements in 2012, where the new MIKE URBAN will transform the way people use hydraulic software. Be more productive and take advantage of the new, scheduled processing features of MIKE URBAN.
Currently our developers work hard to implement calibration plots and reports inside MIKE URBAN. This functionality will support plots of measured and simulated data. MIKE URBAN users will benefit from the possibility to generate series of calibration plots showing corresponding values of measured and simulated data along with comparison statistics in a tabular form. Find out more about other features of MIKE URBAN in one of our next newsletters.

- Support for MIKE 3 Classic result files - including vertical and horizontal slices, sigma layered slices and isosurfaces.
- Extended image draping – meaning that multiple geo-referenced images can be rectified online and draped onto selected surfaces
- Import of solids – solids can be buildings, dams or other types of structures.

- Study in Florida accomplishes reduction in dredging frequency: The Matanzas Inlet in Florida and an Intracoastal Waterway close to the inlet were challenged with high waves and high levels of shoaling. This was due to a close proximity to a natural sandy inlet, causing sediment transport into the Intracoastal Waterway. The challenge of high maintenance requirements of the Matanzas Inlet in Florida has caused the Florida Inland Navigation District to initiate a study to investigate the inlet area and examine alternatives to reduce the sediment inflow into the waterways. The study was performed by Taylor engineering and a coastal model was developed using MIKE21. With concerns to the estimated construction and maintenance cost, a deep sediment basin was chosen, from several alternative solutions, which would reduce dredging frequency in the Intracoastal Waterway to one dredging operation every four years as opposed to the previous average of 2.7 years. Read more here.
- Floating breakwater reduces wave heights in tugboat port in Germany: In one of the major ports, Jade Weser Port, in northern Germany the construction of a temporary tugboat port was challenged by high waves of up to 0.8 m for a mean water level of +3.00 m NN within the port. This was caused by an exposed location of the port affected by primarily eastern and northern winds. A study was conducted for client, Inros Lackner, in order to discover ways of reducing the impact of the winds within the port area using a MIKE 21 Boussinesq wave model (BW). The study determined the actual height of the waves and a simulation of the possible reduction was made. The reached solution became a floating breakwater within the port that would reduce the wave heights of about 10–30 pct. With the combination of expert consultancy and high quality software, they were able to reach a solution that was inexpensive, fairly easy to install, and with great result for the client. For more information, read here or please contact Oliver Stoschek or Anja Brüning.
- New insight into Bull Sharks' behaviour in Australia using individual-based modelling: Studying fish, sharks, and other marine mammals is often a challenge due to lack of accurate information that provides a realistic portrait of their living conditions, movements, and the elements that affect their behaviour. Researchers at Griffith University in Queensland in Australia have recently successfully employed an individual-based modelling technique to investigate the habitat and movement patterns of juvenile bull sharks in the Tallebudgera Creek estuary in Australia. The modelling tools in MIKE21 and ECO Lab were used to accurately capture the hydrodynamics of the estuary to create a virtual habitat and integrate tracking results of a number of juvenile bull sharks. Their work has provided new valuable knowledge and a fairly accurate picture of, which elements affect the bull sharks and their living conditions such as water quality, salinity levels, turbidity, and currents. Thus, this use of individual-based modelling paves the way for new possibilities of researching marine mammals in the future. The research project at Griffith University in Australia is a recent example of how MIKE by DHI supports universities by providing software to PHD and MSc students on very favourable conditions. For more information about individual-based modelling, please contact Michael Potthoff. For more information about the specific research on bull sharks, please contact Jonas Brandi Mortensen.
- Flood modelling enlighten community in Iowa, United States: In 2008, the state of Iowa in the United States experienced severe flooding, where many property owners and entire communities suffered. Since then, Iowa Flood Center (IFC) has used MIKE FLOOD modelling of the severe 2008 floods for community outreach and education. "The Iowa Flood Center (IFC), a state-funded center comprised of IIHR–Hydroscience & Engineering researchers, has been using MIKE FLOOD to simulate flood discharges in several Iowa communities. The simulations have been used to numerically reconstruct the severe 2008 Iowa floods and to develop libraries of static inundation maps relating river stage and discharge to flood extents and depths in each community. The intent is to provide communities and individuals an impression of how river stages and discharges forecasted at discrete points may affect their properties." Nathan C Young, Associate Director, Iowa Flood Center. Read more here. The maps are available on the IFC website as part of the Iowa Flood Information System (IFIS).
- Focused mitigation of hazardous urban discharges: Comprehensive monitoring and modelling of discharges of hazardous substances in the Copenhagen Harbour district revealed the most important point sources of selected substances and thereby allows for a sensible and target-oriented prioritisation of future mitigation measures. The present study determined whether or not specific point sources (e.g. wastewater treatment plants, industries or combined sewer overflow) release significant emissions of hazardous substances as listed in the Baltic Sea Action Plan. It was carried out within the framework of the EU-funded COHIBA-project (Control of Hazardous Substances in the Baltic Sea Region) as a combination of wastewater measurements, load estimations and modelling of the discharges (hydrodynamic marine fate modelling with MIKE 3 and ECOlab).

- Tsunami Hazard Assessment and Emergency Response Planning (MIKE 21): Port of Long Beach, CA and Port of Los Angeles, CA use Advanced Wave Modelling for Tsunami Hazard Assessment and Emergency Response Planning. Interest in assessment of the potential for tsunamis along the southern California coast and the associated impacts to the Ports of Los Angeles and Long Beach was renewed in light of the devastation caused by the recent Indian Ocean earthquake and tsunami of December 26, 2004. Historically, concern for tsunamis along the California coast has been limited to distant sources such as Alaska, Chile, or others. However, a few recent studies have been suggesting potential tsunami sources within the southern California Bight which could have a greater impact to the Ports due to the short travel distance and higher amplitudes than expected from the remote sources. Moffatt & Nichol conducted an investigation of the potential tsunami hazard for the Ports of Long Beach and Los Angeles. A detailed tsunami propagation and inundation numerical model was prepared using DHI's MIKE 21 Boussinesq Wave Model to evaluate several potential sources of a tsunami, including potential subaquatic landslides, a thrust fault, and several strike slip faults capable of producing seafloor uplift.

Welcome to DHI UK
DHI is an independent, international consulting and research organisation with the global objective of advancing technological development and competence with respect to water, in all of its environments.
Worldwide, we offer a wide range of consulting services and leading edge technologies, software tools, environmental laboratories, and physical model test facilities, as well as field surveys and monitoring programmes. Designated as a not-for-profit organisation, DHI is able to invest a considerable portion of its resources in research and development. Today we co-operate with many Universities, and research organisations, and are recognised globally for our innovation and expertise.
In the UK, DHI offers niche or specialist consultancy services in the water and environment market to government agencies, commercial entities and selected research organisations. We fulfil a research based specialist advisor role; a ‘Consultant to the Consultants’. We also supply and support the renowned MIKE by DHI suite of integrated water modelling tools.
MIKE by DHI software is the result of years of experience and dedicated development and has, in many regions, become the standard modelling tool. It transforms our science into practice and gives you the competitive edge and, through the DHI Academy, you can rest assured that there is a local team of highly skilled experts committed to train and support you every step of the way.
MIKE by DHI truly models the world of water - from mountain streams to the ocean and from drinking water to treatment plant and beyond.
