The restoration of Whicham Beck provides ecological benefits, risk reduction and reduced OPEX costs
by Carl Sanders (United Utilities)

Protecting and enhancing natural resources such as rivers, lakes and some of the most beautiful countryside in the country is all part of United Utilities normal business. Baystone Bank, which was constructed over 135 years ago, is north of the village of Millom within the Lake District National Park. The reservoir was taken out of supply over 10 years ago. This article examines the discontinuance of the Baystone Bank dam, which will result in flows returning to Whicham Beck for the first time in over a century. Read more >

Flood Consequence Assessments of Critical Assets
Dŵr Cymru Welsh Water’s assessments of eight infrastructure assets in Wales
by Chris Lewis, Peter Jones and Laura Howe (Waterco Ltd)

The Welsh Government’s Technical Advice Note 15: Development and Flood Risk (TAN15) gives indicative guidance that the annual probability of flooding of general infrastructure from fluvial events should be no greater than 1% AEP (annual exceedance probability) and no greater than 0.5% AEP from tidal events. This paper presents the reasons for the detailed flood risk assessment of eight water assets in Wales in 2011 and also includes the approach, methodology and findings of the hydraulic modelling which formed a key part of the assessments. Brief details are presented of two of the hydraulic models. Read more >

Dear clients and partners,

I am delighted to share with you the results of the rebranding process we have just gone through.

After a decade of strong international growth, we felt the need to reflect on our journey and to agree on the foundation of DHI's future success. We've sought inspiration from our clients, our board members and our own people. I would like to thank all the contributors for their invaluable inputs. It is truly inspiring, when you're inside an organisation, to get a glimpse of the outside-in perspective and to see the realm of opportunities.

We've listened carefully, thought hard and discussed candidly. The result is hopefully an even better DHI - better for you, better for water environments and better for us.

In this special issue of our newsletter, you will discover our new visual identity, our new tagline and two new brands we're introducing to improve accessibility to our knowledge and our technology.

Enjoy.

Previews of MIKE by DHI Release 2012

The MIKE by DHI Release 2012 is just around the corner. As in previous issues of our newsletter, we would like to disclose a preview of the many new and exciting features, which we hope will improve your experience with the software products, regarding usability, productivity as well as enhanced applications.

Introducing ABM Lab

In version 2012 of MIKE by DHI we proudly present a world premiere: Agent based modelling integrated with our hydrodynamic models in two and three dimensions (MIKE 21 and MIKE 3). Agent based modelling (also called individual based modelling) describes the autonomic behaviour and states of agents, objects or individuals. ABM Lab makes it possible to address questions that are beyond the scope of more traditional water quality models. ABM Lab is a flexible numerical laboratory where the user can define agents, their behaviour and states. The Langragian ABM Lab can work with the hydrodynamics alone or it can be combined with the Eulerian ECO Lab, in order to make the agents react to water quality parameters.

Examples of applications are: -

• Coral spawn modelling. Numerical modelling of the impacts of dredging plumes on coral spawning and recruitment
• Modelling eelgrass succession patterns, determining the recolonisation of eelgrass
• The houting project: modelling the migration of salmonide fish larvae through different wetland construction designs
• Modelling of Bull Shark migration patterns in a semi-enclosed eco-system

DHI Group Newsletter - August 2012

Renewable energy forms the subject of the leading article in the latest DHI Group newsletter: -

We are currently witnessing a major transition – the leap from fossil fuels to renewable energy. The better part of renewable energy production is related to water and water environments. At the same time, offshore wind energy is increasingly gaining ground. Tidal and wave power production are still in their nascent days, but they are fast on the road to maturity. As such, the potential in renewable energy generation is immense and grows further as we speak. Read the full article.

Large scale Interactive coupled 3D modelling for wave and tidal energy resource and environmental impact using MIKE Software

Scotland has substantial wave and tidal energy resources and is at the forefront of the development of marine renewable technologies and ocean energy exploitation. Wave and tidal energy devices will soon be deployed in arrays, with many sites being developed. It is therefore essential to understand how a number of multi-site developments collectively impact on the physical and biological processes over a wider region. Careful selection of array sites may enable the optimum exploitation of the resource while minimising any environmental impacts to an acceptable level.

The TeraWatt project is a £1m project funded by the Engineering and Physical Sciences Research Council through its Marine Challenge Fund. The project consortium has been established under the auspices of the Marine Alliance for Science and Technology for Scotland (MASTS) with scientists from the Universities of Heriot-Watt, Edinburgh, Highlands and Islands, Strathclyde, Swansea and Aberdeen, and Marine Scotland Science (MSS). The overarching objective of the research is to generate a suite of methodologies that can provide a better understanding of the impact of energy extraction on the resource. Approaches will also be developed that can be employed to assess the physical and ecological consequences of changes to the resource. The project objective will be met by investigating spatial changes in wave climate, physical processes affecting sediments, the shoreline & seabed, and the impacts on organisms living in the seabed, their distribution and the significance of these for other ecological processes.

MIKE by DHI software has been chosen by the TeraWatt Consortium to support their research. Coupled MIKE 3 FMHD and MIKE 21 SW models form the foundations of the adopted MIKE software platform. These core models will be augmented by MIKE 21 BW, MIKE 3 FMMT, MIKE 3 FMST, LITPACK, MIKE 3 FM ECO Lab & ABM Lab, EVA and MIKE Animator in order to consider the specific responsibilities of each partner university.

For more information about the above MIKE by DHI software, please contact Steve Flood on sjf@dhigroup.com

Previews of MIKE by DHI Release 2012

We are gradually approaching the release of the MIKE by DHI software package 2012, which is scheduled for this October. As in previous issues of our newsletter, we would like to disclose a preview of the many 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.

MIKE FLOOD AD: fully dynamic AD-coupling

Release 2012 introduces a fully dynamic AD-coupling in MIKE FLOOD, which increases the range of applications substantially.

For more than a decade, MIKE FLOOD has offered complex and flexible features for coupling 1D and 2D hydrodynamic models. Flood extents and flood hazards have been some of the key issues for flood modelling. These issues will continue to be of great importance and still be focus points for many modelling applications in the future, but in addition to this, the new release of MIKE FLOOD now offers the option to simulate the transport and spreading of pollutants during a flood event through a fully dynamic coupling of the Advection Dispersion modules of MIKE 11, MIKE 21, and MIKE URBAN.

The new AD-coupling in MIKE FLOOD enables users to simulate new interesting aspects such as: -

• floodplain contamination from polluted rivers
• impact assessment on river quality from pollutant sources in flood prone areas during flood events
• the impact on concentrations of river pollutant in case of a release from an urban Combined Sewer Overflow

MIKE 21 FM: New dike structure option

A new dike structure option has been implemented in the Flexible Mesh series of MIKE 21 and MIKE 3. Dike structures are defined by structure specific data parameters as well as location and geometry. The location in the horizontal domain is given by two or more geo-reference points (a polyline), which defines the width of the structure perpendicular to the flow direction. Each point in the polyline should be given a crest level, and it is therefore possible to obtain a spatial variation of crest elevations along a dike structure within the model domain.

Dike structures are generally used to describe local flow obstructions or other special topographical features, which are not included in the model bathymetry, and as such a highly useful feature for both coastal and inland applications. The discharge over a section covered by the dike is calculated using a standard weir expression.

MIKE SHE: Frozen soil

The 2012 release of MIKE SHE will contain a range of new improvements. Among these are the improvements in simulation of the annual variation of soil infiltration capacity due to freezing and thawing dynamics.

A simplified approach has been implemented, which allows the user to define a time-varying OL-UZ (Overland to Unsaturated Zone) leakage coefficient, and thereby enables the user to control the balance between infiltration and direct runoff from precipitation during all seasons of the year.

Previews of MIKE by DHI Release 2012

We are gradually approaching the release of the MIKE by DHI software package 2012, which is scheduled for this October. As in previous issues of our newsletter, we would like to disclose a preview of the many 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.

MIKE 21: Earthquake bathymetry adjustment tool

In version 2012, a new tool that can assist undertaking of Tsunami-simulations is introduced: earthquake bathymetry adjustment tool. For several years, it has been possible to work with time varying bathymetries (using the landslide option) in MIKE 21 Classic. The usability of this feature is now enhanced, as it will be easier to simulate tsunamis using the new tool. The earthquake bathymetry adjustment tool calculates sea bottom displacements that occur during an earthquake. The output is a time-varying bathymetry file, which can be used in MIKE 21 HD (classic) with the landslide option to generate wave propagation.

The method for calculation of the sea bottom displacements is an amplified version of the double-couple method developed by Okada (1985). The necessary input data for earthquakes can be retrieved from public databases. The tool is available in the MIKE 21 Toolbox in a new group called Seismology.

MIKE MARINE GIS will be discontinued

MIKE MARINE GIS will be discontinued and will not be available on the MIKE by DHI 2012 DVD. It has been evaluated that the user base for MIKE MARINE GIS was not sufficient to maintain the programme on the Esri platform. However, in version 2012, many of the tools that were previously available through MIKE MARINE GIS, have been transferred into MIKE Zero. Thus, we are enhancing the functionalities available for most users: -

• Tools for creation of transects, profiles, baselines, and coastlines are included in the bathymetry editor
• The MIKE Zero tool “Geo Referencing Image File” has been extended to read and convert Esri world format files to DHI world file format
• The MIKE2SHP tool is extended to support mesh and dfsu files

MIKE URBAN: Advisor Tools for modelling water distribution networks

The costs of pipe failures in water distribution networks are increasing and are forcing operators and utility managers to develop strategies and solutions to identify and replace critical pipes. With the upcoming release of MIKE URBAN, a new set of advisor tools will be available to support these processes.

Pipe criticality modelling will predict how the water distribution system responds to: -

• Pipe break situations
• Planned reconstructions
• Limited water supply

Sustainability analyses will help to understand simulation results and detect possible problems, anomalies, and critical areas in the network. In addition to the map layers, a detailed html report will be provided for the entire network as well as for particular zones: -

• Storage tanks: reports tanks that are either drained or overflows during the simulation, reports if the tanks are balanced within the simulation
• Pumps: reports pumps that are operated close to their maximum capacity
• Unit head loss: reports pipes with too high unit head loss
• Service pressure: reports excessive pressure that exceed the service criteria
• Pipe flow: reports reverse flow in pipes
• Flow velocity: reports excessive flow velocity

Furthermore, cost analyses allow for reviewing the energy consumption results in more details, creating tabular outputs and graphs of pump utilisation, average power consumption, and costs.

Numerical modelling of moored vessel motion

DHI has developed the moored vessel response model WAMSIM. The WAMSIM model is an advanced numerical modelling software package designed to support decision makers with fast, accurate and cost effective predictions of motions and mooring forces affecting floating structures. The forcing comes from combined wind, current and wave action. The influence of breakwater and quay structures on the waves is included in the forcing via the hydrodynamics model. Using this tool enables operators to adopt effective mitigation measures early in the feasibility and design processes.

WAMSIM utilises the combined strength of MIKE by DHI’s wave and hydrodynamic models and the industry standard vessel response model WAMIT® by WAMIT Inc. WAMSIM provides time domain predictions of all motions and mooring forces, and can be used to produce informative 3D visualizations, for easy visualisation and result interpretation. The accuracy of WAMSIM has been thoroughly validated against field and laboratory measurements, and have been successfully utilized on projects at a across the globe.

Predicting scour in offshore wind farms

Our research into long-term scour predictions has borne fruit in the form of a specialty tool - WiTuS. With WiTuS, it is now possible to model long-term predictions on scouring around monopile type foundations – structures which form the bases of majority of the current and planned offshore wind farms.

Offshore wind farm establishment is an expensive affair. To add to it, there has been no system in place to predict scouring effects on monopiles over long time spans. Lack of predictability has been forcing investors to spend more on hefty protection measures, to shield monopiles against scouring. This significantly adds on to already heavy investment costs.

Learn more about WiTus in our new case story.

Oil Spill Modelling

Oil spills pose a serious threat to the marine environment and can have dramatic impacts. With our state-of-the-art knowledge and modelling tools we can assist you in predicting these impacts and help you prepare the proper response at the right time.

Integrated Surface and Groundwater Model Review and Technical Guide

The Ontario Ministry of Natural Resources has published a guideline report evaluating the applicability of integrated surface and groundwater hydrologic models including MIKE SHE, GSFLOW, and HYDROGEOSPHERE. While tailored to Ontario watersheds, UK users of MIKE SHE may find the report of interest.

"While integrated models are able to provide a more complete representation of hydrologic processes, they have not yet seen widespread application within Ontario. To address this knowledge gap, the Ontario Ministry of Natural Resources initiated a study to determine the applicability of integrated hydrologic models to Ontario watersheds. The report includes: a qualitative comparison of several integrated model codes; the application of multiple integrated model codes to two case-study watersheds; and guidance to water resource practitioners on how to develop and calibrate an integrated model." from WaterBudget.ca (2011)

Met-Ocean Design Conditions in the Pentland Firth

The Pentland Firth in the north of Scotland is one of the most energetic marine sites in Europe, with tidal currents reaching velocities of up to 12 knots (more than 22 km/h). That makes it highly attractive for tidal energy projects. However, the site is also exposed to severe wave conditions, making it a very challenging environment for such activities. Detailed knowledge of the local Met-Ocean conditions is required to ensure the reliability of any planned tidal devices.

The MeyGen tidal stream project plans to build a 398MW tidal turbine array - generating the equivalent electricity to power 400,000 homes - in the Inner Sound of the Pentland Firth. In order to ensure that the foundations and turbine superstructure are not over- or under-designed, MeyGen Ltd. commissioned DHI to provide design criteria, fatigue and operational Met-Ocean data for four locations at the project site.

The study observed severe wave-current interaction occurring in the area. This occurs when tidal currents are sufficiently strong enough to alter the characteristics of the wave climate. In conditions where tidal currents oppose the waves, extremely steep waves are produced. DHI were able to simulate this process and capture waves of similar steepness to the field measurements.

DHI’s results will be used by MeyGen Ltd to further optimise their turbine design and make sure their structures are able to withstand the harshest conditions expected in their design lives. Moreover, turbine installation can be planned to maximise safety and minimise cost and downtime. Deployment of the first units is planned to commence in 2014.

Queen’s University Belfast: Extensive use of MIKE by DHI for teaching and research.

During the last years several MIKE products, in particular MIKE 21 and MIKE 3, are being used extensively for teaching and research at the School of Planning, Architecture and Civil Engineering at Queen’s University Belfast, Northern Ireland, UK.

Teaching

MIKE 21 is used on various levels of teaching in coastal engineering, both in the class-room and for projects and exercises. Some of the main themes are the estimation of design wave conditions for breakwaters and the influence of dredging on flow conditions in an estuary.

Research

MIKE software has proved to be valuable tools in various research projects, of which can be mentioned (Similarly to other universities much of the research at QUB is made or initiated in connection with thesis studies): -

• Assessment of the effects of Climate Change on wave climate
• Assessment of the environmental impacts of farms of marine energy converters
• Modeling of wave generation over sudden changes in topography
• Saline intrusion and sluice operation in an estuary
• Fate of mussel larvae and spat
• Correlation of benthic habitat composition and hydrodynamic environment

As a part of all these activities, the Queen’s University Belfast has also tested the beta-version of the latest MIKE by DHI release (version 2011).

Dr. Bjöern Elsäßer, Senior Lecturer at the University, states: “No matter what type of research is carried out, the access to state-of-the-art modelling technology is of prime importance. The favourable conditions on which MIKE by DHI software can be made accessible to our Masters and PhD students is certainly a catalyst to our research. For a limited fee the student gets a personal software licence and our university licences can be used for other research and educational purposes. As consultant I’ve been using MIKE by DHI software for many years and have experienced the user-friendly tools and their continuous development as well as the unique support provided by the DHI experts. Based on this experience I felt very confident in introducing the MIKE by DHI modelling technology to QUB and to my students. The user-friendly GUI, the large number of tools within one shell, and the simplicity of getting from a setup to a running model is fantastic. This permits the research part of the thesis work to come into focus instead of only concentrating on setting-up and running a model. Furthermore, it is a pleasure to be able to follow the student’s development and observe how the skills enhance their employability in particular in the competitive working environment.”

Previews of MIKE by DHI Release 2012

As in previous issues of our newsletter, we would like to disclose a preview 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: Finding the ideal discretisation near wells and point sources

The discretisation of point sources (like well boundary conditions) in discretised numerical model is a critical requirement if an accurate drawdown needs to be calculated. At point-type boundary conditions (such as wells or solitary fixed potentials), the element size has a direct influence on the computed drawdown or flux. If being disregarded, the result might vary by up to orders of magnitude.

As FEFLOW uses a flexible meshing technology, the user is able to adapt the element size near wells and other point sources to the necessary discretisation. This ideal node distance depends on the radius of the well in reality and the number of neighbour nodes. To facilitate the calculation and implementation of this distance, multilayer wells and borehole heat exchangers have been equipped with special viewing styles that guide the user on how to adapt the mesh to its ideal shape.

The figures illustrate the easiness of the workflow. First, a mesh is created (e.g. using the triangle method) with an approximated node distance (6 x well radius). Afterwards, a multilayer well is created. The viewing style “ideal element size” displays a circle indicating the ideal distance of the neighbouring nodes. After manually placing the nodes on this circle, the area indicated by the “geometry“-style (well radius in reality) will be matched by the “virtual well radius” (equivalent well radius in the discretised model).

These and many new features are already available in the FEFLOW 6.1 public beta.
