Directions in Urban Drainage Past Present and Future - UDG Autumn Conference and Exhibition 2014

  1. 1. © DHI Recent flood events have raised the profile of flooding, from all sources. At DHI, we truly believe the solution to flooding should not be dictated by the choice or capability of the modelling software. Instead the modelling software should be used to inform and test possible solutions, at a catchment scale. Our integrated modelling software can consider flooding from all sources in an integrated way, as well as considering, for example, the movement of a pollutant, through a pipe system, as it spills overland and is transported away through a watercourse. Sub-surface interactions are also included as our integrated modelling software allows the exchange between pipe networks and groundwater to be modelled, not simply as a gain/loss to the system, but in a fully integrated way. DHI is a pioneer in the development of truly integrated water modelling software. Today, our software is unrivalled with respect to flexibility, accuracy and performance. This allows truly integrated modelling to be undertaken, going beyond hydrodynamics. The MIKE by DHI product family encapsulates more knowledge and covers a wider range of water modelling needs than any similar products. Our software tools are used by professionals in 140 countries across all continents. They are also available in many sizes, flavours and languages – and most recently also in the cloud. Getting access to our global knowledge has never been easier! Crucially our software is supported locally, by technical experts who have many years of consultancy experience. MIKE by DHI represents more than 50 years of research and practical experience – right at your fingertips. We help make you the expert in water environments. MIKE URBAN— INTEGRATED CATCHMENT MODELLING MIKE URBAN is the urban water modelling software of choice when the important parameters for model selection are stability, workflow, openness, flexibility, GIS integration and physical soundness.

  2. 2. 2 MIKE Urban includes: WATER DISTRIBUTION Typical applications include:  Master planning  System rehabilitation and pressure optimisation  Leakage analysis and reduction  Fire flow analysis  Water quality risk analysis STORM WATER AND WASTEWATER Typical applications include:  Master planning  Capacity management and operational maintenance  Wet weather management and overflows, rainfall dependent inflows and infiltration mitigation  Emergency response planning for urban flooding  Evaluation of storm water best management practices and low impact development  Design and optimisation of real time controls  Sulphide gas formation analysis MIKE FLOOD MIKE FLOOD is the most complete toolbox available for flood modelling. It allows you to combine a wide selection of 1D and 2D flood simulation engines, enabling you to model virtually any flood problem. MIKE FLOOD offers a fully dynamic and integrated coupling between urban and river 1D engines and the 2D overland flow engine. This solution provides the full flexibility and capability for investigating complex problems. MIKE FLOOD is applicable at any scale from a single parking lot to regional models. Independent studies show that you can save months of effort and create more reliable models by upgrading from standard 1D modelling to MIKE FLOOD. Typical MIKE FLOOD applications include:  Integrated urban drainage, river and coastal flood modelling  Rapid flood assessments  Flood hazard mapping  Flood risk analysis for industrial, residential or cultural heritage areas  Flood contingency planning (for example, planning of evacuation routes and priorities)  Impact assessments of climate change issues  Flood defence failure studies MIKE FLOOD features: 1D Engines  1D river network (MIKE 11)– based on DHI’s classic hydrodynamic engine for rivers and open channels.  1D sewer network (MIKE URBAN) – based on DHI’s equally classic engine for sewer and drainage networks. 2D Engines  Single Grid – the classic rectilinear model. Easy to set up and easy input/output exchange.  Flexible Mesh (FM) – maximum flexibility for tailoring grid resolution within the model. A range of structures (including culverts and weirs) can be handled both in the 1D and the 2D engines. In addition, operational structures can be included in the 1D networks using add-on modules. The 1D river and sewer engines and the 2D overland flow engines can be coupled to provide fully dynamic and integrated modelling to meet your most complex project requirements. MIKE BY DHI DELEGATE PACK - UDG AUTUMN 2014 © DHI LOCAL AREA WEATHER RADAR (LAWR) DHI has developed a short range weather radar (LAWR) to detect the spatial variation of local rainfalls. This is useful for providing rainfall forecasts with a few hours warning and high resolution rainfall data. The radar measurements may be presented as time series of rainfall for specific catchments or as graphical images of the full radar coverage. This information can be broadcast to the web in real-time. DHI’s weather radar can also be combined with its urban drainage models and thus provide an integral part of urban information and flood management systems.
  3. 3. 3 URBAN FLOODING Today's demand for accuracy often calls for using a 1D pipe flow model combined with a 2D overland flow model. MIKE FLOOD offers such a model combination through the coupling of MIKE URBAN and MIKE 21. MIKE FLOOD efficiently simulates any cause of urban flooding, including heavy local rainfall, insufficient flow capacity of storm water inlets or the drainage network, and flooding caused by overtopping of nearby river or coastal flood defences. An unrivalled dynamic coupling of MIKE SHE (our unsaturated zone model) with MIKE URBAN is also available, allowing the accurate modelling of the two-way interaction between pipes in the ground and the surrounding aquifer. This facilitates the modelling of infiltration to and leakage from pipes as well as the potential side effects of infiltration prevention. RIVERINE FLOODING MIKE FLOOD is an efficient and flexible tool for river flood modelling when investigating flood hazards and flood risk from rising water levels in the river/canal system and/or from high rainfall intensity in the catchment area. Flooding can be investigated on multiple scales. These range from large scale basin areas to local impacts in specific low lying flood prone areas along the river. When simulating river flooding, the combination of a 1D open channel model using MIKE 11 and a 2D overland flow model using MIKE 21 is typically preferred. MIKE 11 and MIKE 21 can be coupled either at specific points or distributed along entire river stretches on either side of the main river channel. COASTAL FLOODING MIKE FLOOD is ideal for efficient and accurate assessment of coastal flood risks, whether they are related to flooding of coastal cities and infrastructures, or to the inundation of reclaimed or low lying areas. GOING BEYOND HYDRODYNAMICS 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 risk management. These issues will still be the focus for many modelling applications in the future. However, in order to support wider EU Water Framework Directive objectives, there will be a need for more detailed studies – particularly water quality assessments. MIKE FLOOD now offers the option to simulate the transport and spreading of pollutants during a flood event. This is done via a fully dynamic coupling of the Advection Dispersion modules of MIKE 11, MIKE 21, and MIKE URBAN. MIKE BY DHI DELEGATE PACK - UDG AUTUMN 2014 © DHI / Photos: iStock © Mike Bentley WANT TO GO FASTER? Graphical Processing Unit (GPU) MIKE FLOOD and MIKE 21 FM HD are ‘GPU-card enabled’ which means that it is possible to use the graphics card on your PC to speed up simulations very significantly. The latest release supports both single and multiple GPU cards. High Performance Computer (HPC) MIKE 21 FM and MIKE 3 FM have been installed in HPC centres around the world. Running models on HPCs can speed up simulations even beyond the speed of the GPU version. Software as a Service (SaaS) If you need more PCs to run models, users with a valid service agreement can access, at preferential rates, more MIKE software and virtual PCs in the cloud through our MIKE by DHI SaaS portal. The portal can be used not only for modules you already own but also for modules you are considering buying or that you only need for a brief period of time. USING MIKE FLOOD AD TO MODEL POLLUTED FLOOD WATERS AND RIVERINE WATER QUALITY MIKE FLOOD now includes the option for a fully dynamic 1D-2D Advection Dispersion coupling, which increases the range of applications substantially. The new AD coupling in MIKE FLOOD enables users to simulate new interesting aspects such as: -  The impact on concentrations of river pollutant in case of a release from an urban Combined Sewer Overflow.  Floodplain contamination from polluted rivers.  Impact assessment on river quality from pollutant sources in flood prone areas during flood events. MIKE FLOOD AD can be further enhanced by ECOLab for advanced water quality simulations. ECOLAB ECO Lab is the complete numerical laboratory for water quality and ecological modelling. You can develop exactly the model you need and describe the processes you wish. No ecological problem is too simple or too complicated for ECO Lab:  Open Equation solver for coupled ordinary differential equations.  Designed for point descriptions of processes of chemistry, ecology, etc.  All equations, parameters contained in flexible, portable ECO Lab templates (use DHI supported templates or create your own).  Integrated with DHI’s hydrodynamic models: Currently MIKE 11, MIKE 21 (hence MIKE FLOOD), MIKE 3 & MIKE SHE.

WEST can be used for:  Evaluation of Design Options  Process Optimisation  Model Calibration  Development of Advanced Control Strategies  Monitoring of Plant Operation and Troubleshooting  Research and Development  Modelling Integrated Urban Water Systems GROUND WATER AND PORUS MEDIA FEFLOW is our state-of-the-art integrated groundwater software package. It is used for the modelling of fluid flow, transport of dissolved constituents and heat transport processes in the subsurface. FEFLOW could be used to simulate the regional groundwater flow in the capture zone of a water supply well. FEFLOW excels at groundwater-surface water interaction. However, FEFLOW is not only a powerful tool for groundwater modelling. It is also a very general simulation tool for a wide range of problems involving flow and transport of contaminants or heat in porous media. FEFLOW is also used extensively for the modelling of contaminants from abandoned mines and for the simulation of geothermic energy systems.

The Aarhus project was a forward-looking one and was a co-operation between Aarhus Municipality and Aarhus Water. The project consisted of three phases: analysis and design (2006-2007), implementation of infrastructure (2007-2012) and integrated model-based control and warning (2009-2013). At the analysis and design stage, the project aim was to forecast the water quality in the harbour and optimise the capacity of the drainage system and the wastewater treatment plants. At the implementation stage, 50 million EUR was invested in infrastructure (consisting of retention basins, disinfection at WWTP and basin and increased hydraulic capacity at WWTP) and an optimised control system (consisting of integrated real time modelling/ control of sewer system and WWTP and an early warning system). The project has delivered hygienic bathing water in Lake Braband and in the harbour and improved water quality in the River Aarhus. The bathing water forecast service provides the public with information on bathing water quality via an App and a web-based public warning system.
