Local Flash Flood warning System

Read more >>>
Our Local Flash Flood Warning System uses a combination of data processing, modelling and communication tools to give you the timely and accurate forecasts required to aid in proper decision making. It considers the catchment area as a whole – including flood plain and tributaries – thereby providing a more integrated, flexible and holistic approach to forecasting flash floods.

Conventional flood warning systems mainly focus on discharge predictions in the main rivers. However, local floods in smaller streams and tributaries (not generally covered by conventional warning systems) may cause a large amount of damage – particularly in urban areas.

Our Local Flash Flood Warning System overcomes this challenge by considering the entire catchment area as a whole. The system is based on existing and newly developed components of our MIKE CUSTOMISED by DHI framework. It effectively utilises a large variety of input data, sophisticated mathematical models, and advanced hydrological analysis processes.

Some of the key benefits of the system: -
  • Ability to effectively forecast local flash floods by covering the entire catchment area
  • Frequent forecast updates appropriate for local dynamic rainfall events and storms
  • Flexibility in terms of connecting to data sources
Predicting long-term shoreline movements

Read more >>>
Detailed sediment transport description from our two-dimensional (2D) coastal model, combined with a shoreline evolution model can help to effectively predict long-term shoreline movements. Our solution can thereby enable long-term forecasts of impacts of coastal structures on coastal processes and thereby help maintain integrity of the coastline.

Valid predictions of long-term shoreline movements are vital to mitigate or prepare for erosion and changes in coastal stability. Our new shoreline model introduces the concept of a 1-line model for shoreline evolution within the MIKE 21 FM framework. The model can be applied to problems over a longer time scale. This is due to the simplifications imposed on the morphologic evolution of the coastal profile, when compared with the existing two-dimensional (2D) morphological model MIKE 21 Coupled FM.

Some of the key benefits of the new shoreline model: -
  • Ability to calculate stable shoreline and shoreline envelopes and compare shoreline movements for different scenarios
  • Inherent inclusion of the effects of coastal structures in the shoreline model
  • Ability to make long-term predictions of coastal structure interactions and their impact on coastal processes
  • Maintenance of coastal profile integrity
Helping you select the best aquaculture sites for optimal production

Read more >>>
At DHI, our advanced modelling techniques and environmental and hydrodynamic expertise can help you identify optimal sites for aquaculture production. Our innovative solution combines our knowledge of chemical and biological conditions with the three-dimensional (3D) hydrodynamic modelling of our MIKE by DHI software.

The selection of suitable sites for marine aquaculture is essential for economically viable production. Different environmental requirements, such as light, nutrients, oxygen and water column stratification, must be taken into account, during such site selections.

With our 3D MIKE model and extensive knowledge, we can help you identify the best areas for optimal aquaculture production throughout the year. We can also calculate and quantify potential disease dispersal, helping you identify more safe places for future aquacultures location. Moreover our site selection tools can aid you in selecting sites with high dilution capacities to ensure that medical products and copper do not exceed the maximum allowable concentration.

Marine application

3D model (MIKE 3 FMHD with MIKE 3 FMPT)

Two simultaneous releases both made at 3.0m below the water surface. The square markers are the neutrally buoyant particles (e.g. bacteriological effluent), and these are permanently deposited (i.e. not re-suspended) upon contact with the bed. The triangular markers are negatively buoyant particles that have a positive fall velocity (e.g. sand), these are allowed to re-suspend upon contact with the bed. The reduced flow speeds near the bed (from the 3D model) can be clearly seen by the movement of the sand particles. Marker colour changes to represent the vertical position of the particle.

Riverine application

2D model (MIKE 21 FMHD with MIKE 21 FMPT)

Neutrally buoyant particles released at bed level in a river with a varying flow. The trails show the previous location of the particles (for the last 3 time steps).

MIKE to Google Earth Datum Shift

Google Earth is using the ellipsoid WGS84 to define geo-positions on the earth. If the dfs2 file uses a projection that is based on another ellipsoid the area may not be displayed correctly compared to the satellite images. In this case it may be necessary to apply Datum shift in addition to the automatic coordinate transformation in order for the image to be located correctly.

Here you can specify the parameters needed to transfer the data from the defined map projection into the domain used by Google Earth.

You can read more about Datum Conversion in the Geodesy manual supplied with the installation (MIKE_Zero_Geodesy.pdf).

Previews of MIKE by DHI Release 2014

Approximately once a year, we release a new version of our MIKE by DHI software - and this year is no exception. We would like to reveal herewith a preview of some of the new and exciting features to be released in December. We hope these new features will improve your experience with our software products, regarding usability, productivity as well as enhanced applications.

New possibilities of including moving objects in your animations

Ever wanted to add moving objects to your animations? This is possible with Release 2014.

Click here to view an example of the
possibilities of this new feature.
In the September issue of this newsletter, we included a preview of new features in MIKE Animator Plus in Release 2014. In this issue, we would like to show you an example of the possibilities of this new development.

With MIKE Animator Plus, you can create visual animations to present you model results – and as something new, you will be able to include visualisation of solids. Through the inclusion of solids, you can improve your animations significantly by enhancing realism and recognition of locations, for example by including fixed elements like buildings and dams or moving elements like ships. Release 2014 will support the placement of solids inside the model domain and allow them to move, which means that a ship can be sailing as part of the animation.

MIKE HYDRO Basin: Global prioritisation of water users

MIKE HYDRO Basin is our new generation of integrated river basin analysis software for water resources planning and management.

MIKE HYDRO Basin was introduced with the current release 2012, containing a large number of features relevant for integrated river basin management applications. Developments continue for MIKE HYDRO Basin and the new release will introduce another very interesting new feature to modellers of river basin water allocation schemes and resources management; Global Prioritisation.

With this new feature, it is now possible to include a user defined prioritisation of water users within the basin model - regardless of their geographical location within the basin. Thus, it highly increases the applicability of MIKE HYDRO Basin for specific types of water resources management applications.

The global prioritisation of water users are defined through ‘Ranking’ number definitions, where water consumers are assigned an individual ranking number. The ranking numbers are used during simulation to prioritise consumers, in case of water shortage, in order to accommodate the water demands for these - taking into account that some users have a higher priority than others.

Mesh Generation: A new tool for creating flexible meshes from dfs2 files and other sources 

The combination of high flexibility of flexible meshes (FM) and impressive performance improvements, introduced in the latest releases of MIKE by DHI, make the use of FM versions of MIKE 21, MIKE 3 and MIKE FLOOD even more attractive. Improvements in recent releases include, amongst others, the introduction of shared memory based parallelisation, porting of simulation engines to LINUX and, in Release 2014, supporting Graphical Processing Units (GPUs) for MIKE 21 HD FM.

In order to assist those, who want to transfer existing models or bathymetries into the FM system, Release 2014 will contain a new tool, aimed to convert bathymetries in other formats into FM format.

The new Mesh Converter is included in the MIKE Zero Toolbox and supports DHI’s own format from the ‘classic’ modelling series, dfs2 as well as some external formats (ADCIRC, SMS, TUFLOW). The process is quick and easy and produces an equal bathymetry in FM format, which can then be modified using all the existing editing facilities of MIKE Zero’s Mesh Generator.

New features in FEFLOW 6.2

FEFLOW 6.2 offers a number of new features to enhance your groundwater modelling work.

Groundwater age calculation in FEFLOW 6.2
Groundwater Age is a new type of problem class, similar to mass or heat transport. With this, many questions can be easily answered, such as:
  • How long is the average underground travel time of water pumped at a well?
  • What‘s the percentage of bank filtration at the supply wells?
  • What‘s the age and remaining travel time of groundwater at a certain location?
New storage capture/release component in FEFLOW 6.2
Storage Capture/Release is a new component in the Rate Budget and Period Budget Panels for flow and transport in FEFLOW 6.2. With this new component, you can clearly separate storage change and solution error in transient models.

Increased performance with new MIKE 1D features in MIKE URBAN

In 2012, we introduced a new generic 1D numerical engine for MIKE by DHI products. With the upcoming release of MIKE URBAN 2014, a number of new features for MIKE 1D will be available such as:
  • coupling to MIKE SHE
  • options for Advection-Dispersion modelling
  • result presentation in MIKE URBAN
  • and many more…
MIKE 1D is parallelised and makes use of multicore PCs, which means that most users will experience higher modelling performance. Now is the time to start using MIKE 1D in your new modelling projects!

Strengthening wastewater modelling projects with new features in WEST 2014

Our WEST software package, for modelling wastewater treatment plants, has quickly established itself as an important product in the MIKE by DHI family with a growing number of users all over the world. Release 2014 includes several important new features, including:
  • New Report Generator, which enables the user to automatically create reports containing graphs and data pertaining to a project in a variety of formats including: project information, plant layout, plots and tables.
  • Integrated urban water system (IUWS) libraries, making WEST a powerful tool for identifying synergies and to globally optimise the wastewater system performance on a catchment scale.
Inclusion of plant wide model (PWM) in the WEST 2014 model library

We are also pleased to inform you that Release 2014 of WEST will include a plant wide model (PWM) for simulating nutrient removal activated sludge systems.

The plant wide model, ‘PWM_SA’, is a three phase model for the simulation of nutrient removal activated sludge systems coupled with the anaerobic (organisms independent of oxygen), aerobic (organisms dependent on oxygen) and anoxic-aerobic digestion of sewage sludge. This includes waste activated sludge produced by biological excess phosphorus removal plants. The model is based on strict material mass balance and is prepared by linking:
  1. a variation of ASM2 for activated sludge nitrogen and phosphorus removal and aerobic or anoxic–aerobic digestion
  2. a variation of the UCT anaerobic digestion model.
The main extensions to the original models are through their integration within a three phase mixed weak acid/base chemical and physical processes models of the inorganic carbon, ammonia, acetate, propionate and phosphate systems.

The plant wide model is developed jointly by our WEST Development Centres, the Universities of Cape Town (UCT) and kwaZulu-Natal in South Africa.

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.
