MIKE FLOOD successful in the second UK Environment Agency 2D model benchmarking study

We are pleased to announce that MIKE FLOOD have once again taken part in the UK Environment Agency (EA) benchmarking study; ‘Benchmarking the latest generation of 2D hydraulic modelling packages’.

MIKE FLOOD EA Benchmarking Report

The Environment Agency has recently concluded a revised benchmarking study with the overall objectives to:

a) provide an up-to-date picture of capabilities of the latest generation of 2D modelling tools

b) to create evidence that 2D flood inundation modelling packages, used for flood risk management by the Environment Agency and its consultants, are capable of adequately predicting the variables on which flood risk management decisions are based.

MIKE FLOOD was once again successfully applied to all of the predefined test cases developed by the EA. Model applications range from small scale laboratory models to real case flood modelling applications requiring stand-alone 2D modelling or 1D-2D coupled modelling with either river or urban pipe network coupled to the 2D overland flow model. MIKE FLOOD performed with excellence and delivered the simulation results expected for all test cases - both in terms of hydrodynamics and computational performance. For more than 10 years now MIKE FLOOD continues to prove its robustness and superior applicability in a large variety of flood related applications.

Use MIKE CUSTOMISED IMS to support your MIKE by DHI modelling activities

MIKE FLOOD EA Benchmarking Report

MIKE CUSTOMISED IMS (Information Management System) is now available for use with MIKE by DHI software.

MIKE CUSTOMISED IMS builds on a database that stores time-series data and spatial data. It allows you to establish spatial associations between spatial features and time-series and it comes with a long range of built-in data processing tools that you can use when you prepare your data for modelling or when you analyse or process results.

In case you need to develop your own tools, you can do this using the built-in Python scripting component or you can use the embedded spread sheet component. The spread-sheet component is also a strong reporting component that allows you to create sophisticated and interactive views containing, tables and charts similar to what you do in Excel. In addition to the sophisticated components for handling time-series, GIS, scripts, performance indicators, spread sheets, documents and so on, the IMS also comes with an overarching and configurable user interface. Through this user interface you have various options for searching and filtering data. You can make your favourite tools, charts and maps easily accessible. MIKE CUSTOMISED IMS links directly to our dfs files (import/export) but also contains a series of other data bridges.

We are currently implementing MIKE CUSTOMISED IMS on a number projects. Among the larger projects is the “Lake Victoria Information Management System” and the “National Water Information System” in South Africa.

MIKE CUSTOMISED IMS is useful both as a large corporate IMS that helps you create a central corporate repository for your water related data and as a personal IMS for data management in relation to your MIKE by DHI modelling work.

Product news

Previews of MIKE by DHI release

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

Introducing MIKE 21 GPU - the fastest 2D solver ever!

If you are using MIKE 21 FM HD or Flexible Mesh solver with MIKE FLOOD, you are getting a pleasant surprise with Release 2014! With the new release, your update package will automatically include a brand new version of the MIKE 21 FM HD module. The new version, MIKE 21 GPU (Graphical Processor Units), is “GPU-card enabled”. This means that it is able to use the graphics card on your PC to speed up simulations significantly.


Simulation time in seconds for a high resolution Mediterranean model with and without GPU card. (MIKE 21 FM running single precision, first order scheme).

Speed up you models
Depending on the model setup and the type of GPU, the speed-up can be a factor 100 or more compared to running the same simulation on a single processor CPU.

For some model setups and GPUs, this also means that MIKE 21 FM is now faster than MIKE 21 “Classic” - the single grid version of MIKE 21 HD - when using exactly the same rectangular mesh.

The technology behind MIKE 21 GPU: How does it work?
The computational engine of MIKE 21 FM HD has been reprogrammed to make use of the latest graphical processor units - hardware that is otherwise typically used for speeding up computer games.

How will I get MIKE 21 GPU?
MIKE 21 GPU will become available, at no extra cost, to all owners of corporate licences of MIKE 21 or MIKE FLOOD with valid SMA. This means that there will be no licence fee and no increase in SMA costs. If you do not have a valid SMA or if you own a personal licence, you will be able to purchase it as an upgrade to your existing software.

Where can I read more about MIKE 21 GPU?
We have produced a detailed performance report, including comparisons of the performance of MIKE 21 GPU with the non-GPU enabled MIKE 21 FM HD. Click here to read the report.

Introducing exciting new possibilities in MIKE Animator Plus

MIKE by DHI case story

Version 2012 of MIKE by DHI included a completely re-engineered version of MIKE Animator, designed to be a very flexible tool for producing high quality video animations of modelling results. The most prominent new features in version 2012 were the support of MIKE 3 files (including the ability to slice and take out transects and iso-surfaces) and also improved picture draping functionality.

We have continued the development of MIKE Animator Plus and version 2014 will contain three new and interesting possibilities:

Visualisation of solids: Enhancing realism and recognition of locations
The inclusion of solids can improve the animations significantly through enhancing realism and recognition of locations, for example by including fixed elements like buildings or dams or moving elements like ships. Version 2014 will support the placement of solids inside the model domain. These elements have to be created in 3DS format and then loaded into MIKE Animator Plus. Moreover, they can move inside the animation, which means that a ship can be sailing as part of the animation.

Visualisation of particles: Enhancing result communication
Output files with particle trajectories from the Particle Tracking (PT) modules (MIKE 21 PT and MIKE 3 PT) and from the Agent Based Modelling (ABM) modules (ABM for MIKE 21 and MIKE 3) will now be supported in MIKE Animator Plus. This will enhance the possibilities for result communication from these modules significantly. Click here to view an example.

Support of MIKE SHE files: High quality animations of MIKE SHE results
Also, output from MIKE SHE will now be supported in MIKE Animator Plus in order to allow for high quality animations of MIKE SHE results. This will include animation of overland flow as well as 3D groundwater flow.

New water quality option in MIKE HYDRO Basin

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

MIKE HYDRO Basin was initially 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 one of the new exiting features being introduced in release 2014 is the option of applying water quality simulations within your river basin management applications.

Water quality options in the basin management software package have traditionally been limited to a few hard-coded water quality formulations. However, the new release will include a major upgrade in that respect, as water quality modelling in MIKE HYDRO Basin will be using the open and very flexible ECO Lab modelling framework. This will allow you to alter existing water quality templates or create your own model templates from scratch. Therefore, the ECO Lab option will greatly enhance the options for applying tailored water quality modelling for your particular water resources management or planning project.

Keeping the coastal communities of San Francisco Bay safe from floods

MIKE by DHI case story

Click here to read the full case story.

We helped the United States Federal Emergency Management Agency (FEMA) improve floodplain management practices for counties in the San Francisco Bay Area. We did so by examining the flood risks for the entire San Francisco Bay Area shoreline. Using MIKE 21, we developed 2D regional scale coastal models of the San Francisco Bay in order to predict: Extreme tide (astronomical tide plus storm surge), swell entering from the Pacific Ocean and sea waves generated from local winds in the Bay.

The data from our models provided robust and reliable region-wide information for flood risk analysis. As such, the results were key components for the development of Flood Insurance Study (FIS) floodplain maps for the entire Bay Area.
