Topography Adjustment Tool for MIKE 21 / MIKE FLOOD (A MIKE by DHI Software Custom User Tool)
The Topography Adjustment Tool is a MIKE by DHI Software Custom User Tool developed for the purpose of automating the process of using polygon shape files to adjust topography values in dfs2 files used in MIKE 21 surface water flow models. The main application of the tool is to use a polygon shape file of buildings to automatically assign land values to the dfs2 grid cells which are intersecting the building polygons. However, the tool has been designed such that it can also be used to ‘burn’ roadways into the dfs2 topography. In fact, although the tool is primarily intended for adjusting topography, it can be used to adjust any .DFS2 file using a polygon shape file to select the grid cells of interest.
NB: The Topography Adjustment Tool is provided ‘as is’ and is not part of the commercially distributed MIKE by DHI software products. As such, it is not a supported software product and technical support is not available. Additionally, the Topography Adjustment Tool was developed to work with the 2012 Release format of .DFS2 files but it is expected it will work with some earlier versions of dfs2 files and will continue to work for future releases as long as major changes are not made to the structure and content of .DFS2 files.

MIKE 21 Quick Start Guide (Flexible Mesh Series)
Over the past few months, we have prepared several short instructional documents in the use of the MIKE Zero Mesh Generator, MIKE 21 FMHD and MIKE 21 SW from a UK perspective. These instructions have been collated into the informal working document 'MIKE 21 Quick Start Guide' below: -
We have been working hard to enhance our User Manuals and Scientific Documentation. For example, the above informal guide can be augmented by our new Mesh Generator Step-by-step Guide (2012): -
How to Create a Directional Wave Spectrum for Input to MIKE 21 SW from Buoy Data
In order to make best use of the new Wave Spectra Converter tool available in Release 2012, some pre-processing of wave buoy data is generally required. In response to a number of recent enquiries, we have prepared the following informal guidance: -
Oil Spill Modelling
It is important to note that the methodologies of the old and new oil spill models in MIKE 21/3 are very different, and a direct comparison is difficult. However, in order to provide some basic guidance, we have developed the following comparison document and associated example models (provided here for information and discussion only): -

Australian Rainfall and Runoff 2012 (AR&R) Guidelines Launched: Two Dimensional Modelling in Urban and Rural floodplains
Engineers Australia has published new guidelines on Two Dimensional Modelling in Urban and Rural Floodplains. The guidelines have been prepared for the National Committee on Water Engineering as one of the Australian Rainfall and Runoff Revision Projects.
The Guidelines review current practice in 2D modelling, including areas where current practice is not supported by theoretical and empirical research, and provide guidance on appropriate development and usage of 2D hydrodynamic models for floodplain applications.
While tailored to Australian flood risk legislation, UK users of MIKE FLOOD may find the report of interest (particularly, for instance, the sections on building representation and the use of eddy viscosity in 2D inundation models).
The report builds in part upon the research undertaken by Grantley Smith (University of Newcastle, NSW) on 2D Flood Modelling in Urban Areas (specifically in Merewether; a suburb of Newcastle, New South Wales) which he presented at the 2012 UK User Group Meeting.

Top award for Managed Aquifer Recharge (MAR) Scheme using FEFLOW
The Fortescue Metals Group (FMG) recently won top honours at the International Water Association’s prestigious Project Innovation Awards at the World Water Congress in Korea. The prize was awarded for an innovative Managed Aquifer Recharge (MAR) scheme at Fortescue’s Cloudbreak and Christmas Creek iron ore mines in the Pilbara region of Western Australia. DHI provided assistance to FMG in the design and development of high-spatial-resolution groundwater models using FEFLOW for this project.
The MAR scheme mitigates environmental impact of surface discharge and dewatering drawdown and conserves brackish water resources for future mine water supply. The mine operations are bounded on the south by the Fortescue Marsh, an ephemeral wetland of national significance that is underlain by hypersaline groundwater. The project is one of the largest MAR schemes in Australia and is the first of its kind in highly saline groundwater.
Figure: A Simplified Schematic of The Cloudbreak Managed Aquifer Recharge (MAR) scheme
The MAR scheme is part of the mine dewatering operation. The scheme allows FMG to pump almost 75% of the extracted water back into the local groundwater system instead discharging it to streams, where it would be largely lost to evaporation in the arid climate. The current operation has been operating as a sustainable ‘closed’ system with zero surface discharge since September 2009. The FEFLOW models enable FMG to predict the movement of the saline/brackish groundwater interface in response to different operating conditions. The models also help forecast the quantity and salinity of groundwater extracted under different mine plans. The current 40-gigalitre/year operation may grow to over 100 gigalitre/year as the Cloudbreak mine expands and the Christmas Creek mine comes on-line.
The Fortescue project showcases how Managed Aquifer Recharge, together with FEFLOW, can be used to meet a range of objectives in a complex environment, including coast aquifers. MAR is relevant in many environments, and is likely to be increasingly used at mine sites around the world facing varied and difficult water management challenges.

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.

MIKE by DHI 2012 – software for WATER ENVIRONMENTS
We are pleased to announce that the MIKE by DHI 2012 software package is officially released!
The 2012 version offers new important features and significant performance improvements, which increase speed and productivity significantly and allow you to handle much larger amounts of data in an efficient manner. This provides many new possibilities and facilitates the work of practitioners and decision makers around the world even further.
MIKE by DHI covers the entire water environments cycle in a highly integrated manner and with more features than ever before. Whether you are working within marine, ports and coasts, water resource management, rivers, flooding, urban, groundwater, wastewater or integrated modelling, MIKE by DHI 2012 is tailored for your modelling needs.
Now, with release 2012, running models and simulations with MIKE by DHI software has become even more efficient allowing you to work faster and with much more comprehensive and complex models than ever before. To mention a few highlights of the many improvements, we are proud to introduce high performance computing (HPC), where you can get access to high performance versions of the FM series as well as remote execution in order to avoid large models monopolising your local PC. Getting access to MIKE software has never been easier, and with MIKE by DHI in the cloud and high performance computing versions available, large and complex simulations will never again be an obstacle to reach the best possible results.
Furthermore, when dealing with climate change adaptation, two important improvements have been made, which are the inclusion of Sea Level Changes and the support of 2D data files in the Climate Change tool. Climate change adaption continues to play a major role and will impact us through water first, and with these new features it is even easier to be prepared.
For more information about the many new features of this release, read more here or check out our new online catalogue here.

Congratulations to Plymouth University on the official opening of its new Marine Building
Plymouth University's new £19 million state-of-the-art Marine Building was officially opened by HRH Prince Philip The Duke of Edinburgh on 30 October 2012. The facility is currently thought to house the UK's most sophisticated wave energy testing tank which will enable developers to test wave energy devices (using waves, currents and wind) prior to linking up to the Wave Hub – a grid-connected test site about 10 miles off the coast at Hayle in Cornwall.
More details can be found via the links below: -
To celebrate the opening of its new Marine Building the University commissioned Alexis Kirke and Sam Freeman to create and perform a unique musical composition for large-scale wave tank, water drummers and electronics. The piece, Sound-Wave, is thought to be the first time a wave tank has been turned into a musical instrument.
Alexis Kirke, with sensors strapped to his body, conducted the 12-minute symphony of waves and music from a position above the main tank. Water drummers (Josie Boucharde, Philip J. Kendall, Magdalena Walker and Jennie Pinhey) provided percussion in the nearby coastal tank. Visit Alexis Kirke's web page to see how it was done.

Baystone Bank Impounding Reservoir Safety
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.
Asger Kej

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: -
As a part of Release 2012, we are also happy to announce the first release of MIKE HYDRO.
MIKE HYDRO is our new, common Graphical User Interface framework, which offers the latest generation of a map-based, easy to use and work-flow oriented user interface. The user interface has the Graphical View as a central component for definition and editing of model features, a Tree-view for easy navigation through model elements and tabular property views for efficient, bulk-editing of model parameters.
Through a staged implementation, MIKE HYDRO will become the common Graphical User Interface for most of DHI's Water Resources products and new features and products are added in coming major releases.
The first MIKE HYDRO release includes our Basin module, which is a multipurpose, map-based decision support tool for integrated river basin analysis, planning and management. MIKE HYDRO Basin is designed for analysing water sharing issues at international and national or local river basin level.
Typical applications of MIKE HYDRO Basin include: -

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.

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: -
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.
