MIKE by DHI Software for truly integrated catchment scale modelling

  1. 1. © DHI Traditional approaches to flood risk management in the UK have focussed primarily on the physics of flood water inundation from rainfall, rivers and the sea. An understanding of the processes involved is critical in defining the level of flood risk and in establishing an appropriate level of defence. However, the effects of both natural catchment characteristics and upstream intervention on downstream communities must also be considered. Indeed, in many cases, the response of flood waters in the existing natural environment can, and should, be used to inform catchment scale design and mitigation planning. We believe that accurate modelling of flood risk and natural management options is essential to the decision-making processes that can deliver flood resilient communities. DHI was 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 the wider aspects of natural flood management to be taken into consideration. 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! 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.

  2. 2. 2 MIKE SHE excels at:  Integrated catchment hydrology  Conjunctive use of surface water and groundwater  Irrigation and drought management  Wetland management and restoration  Environmental river flows  Floodplain management  Groundwater induced flooding  Land use and climate change  Nutrient fate and management  Groundwater remediation  Integrated mine water management With MIKE SHE you can investigate individual processes of the hydrological cycle in detail and tailor the integrated model to your needs by selecting the relevant level of detail for each of the processes included in your model. MIKE SHE includes 2D overland flow capabilities and full riverine hydrodynamics (with MIKE 11). It thereby delivers a powerful 1D-2D flood modelling tool, where evapotranspiration, infiltration and groundwater are relevant. For detailed groundwater-surface water interaction studies (including water quality), MIKE SHE includes 3D, finite difference groundwater flow, which discharges groundwater drainage directly to surface water. An unrivalled dynamic coupling of MIKE SHE 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. MIKE HYDRO BASIN—INTEGRATED RIVER BASIN PLANNING MIKE HYDRO Basin 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, national and local river basin level. A comprehensive, yet easy to use, product for those who solve water allocation problems at all scales. A learning tool for investigating options and making informed decisions. Typical MIKE HYDRO Basin applications:  Integrated water resources management (IWRM) studies  Solve multi-sector water allocation problems  Improve reservoir and hydropower operations  Conduct transparent water resources assessments  Evaluate irrigation scheme performance and crop yield With MIKE HYDRO Basin you can:  Create a unique overview of basin data  Work efficiently and create results  Establish transparency in your work  Develop inspiring stakeholder workshops  Overcome organisational barriers MIKE BY DHI DELEGATE PACK - CIWEM 2014 © DHI ASSESSING THE IMPACTS OF RURAL LAND MANAGEMENT CHANGE ON FLOODING AND FLOOD RISK (THE CATCHMENT APPROACH) MIKE SHE is a very powerful tool for assessing the effects of natural flood management schemes in the UK. The software has been used extensively for modelling wetland restoration in upland areas in different parts of the world. The effects of tree planting, water meadows, and other riparian planting can be described by land use changes in the model and the impacts on evapotranspiration, unsaturated flow and surface runoff examined. It is also possible to describe the detention of water in the floodplain (for example, as a result of tree planting, landscaping and so on). The effects of cutting off drains, and altering surface flow routes, can be modelled using the MIKE SHE 2D Overland Flow module. Channel restoration and green bank protection can be handled by coupling with MIKE 11. Natural flood management has many benefits (habitat creation, nature conservation, pollution mitigation and so on). It is of particular interest in rural rapid response catchments, where it is not always possible to provide flood defences. AQUA REPUBLICA Aqua Republica is a DHI and UNEP-DHI project that focuses on the development and promotion of a not-for-profit serious game in collaboration with a number of partners. The aim of the project is to promote sustainable water resources management by sharing knowledge, to raise awareness and build capacity in some of the most critical issues in water resources management through serious gaming, where participants can experience making decisions in managing a catchment in an interactive and engaging way, and in doing so learn about the connectivity and importance of water resources, as well as the need for careful management. While the world of Aqua Republica is fictitious, the challenges of sustainably managing a limited supply of water resources in a situation of growing demand between multiple users and uses are very much based on real life scenarios.
  3. 3. 3 MIKE FLOOD MIKE FLOOD is the most complete toolbox available for flood modelling. It includes a wide selection of 1D and 2D flood simulation engines, enabling you to model virtually any flood problem. Whether it involves rivers, floodplains, floods in streets, drainage networks, coastal areas, dam, levee and dike breaches or any combination of these – MIKE FLOOD provides results. 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:  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  Integrated urban drainage, river and coastal flood modelling MIKE FLOOD features: 1D Engines 1D river network – based on DHI’s classic hydrodynamic engine for rivers and open channels. 1D sewer network – 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. It is now available with parallel processing. Flexible Mesh (FM) – maximum flexibility for tailoring grid resolution within the model. The FM engine supports parallel processing. 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 and 2D engines can be coupled to provide fully dynamic and integrated modelling to investigate complex problems. MIKE FLOOD features a fully dynamic and integrated modelling approach for coupling Riverine, Urban and 2D Overland models depending on your project requirements. 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 CS (Catchment Systems) 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. 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. The flexibility of the combined 1D-2D engines provides numerous opportunities for analysing complex issues such as:  river conveyance problems due to improper maintenance of the vegetation  limited flood storage capacity  infrastructures crossing the river/floodplain  operation of hydraulic structures and reservoirs  dam breaks or levee breaches  changes in land use 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. MIKE FLOOD offers the possibility to investigate the effects of coastal protection, such as dikes/polders and tidal gates or other operational structures in delta areas. MIKE BY DHI DELEGATE PACK - CIWEM 2014 © DHI / Photos: iStock © Mike Bentley CARM CARM is a Decision Support System built around our MIKE CUSTOMISED by DHI and MIKE by DHI software. CARM integrates our fully hydrodynamic models, which reproduce key catchment and river processes, with real-time measurements for the entire catchment system. This information can then be used to make catchment based decisions (for example, around the timing and magnitude dam releases) to optimise water use within a catchment.
  4. 4. 4 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. MORPHOLOGY The primary long-term factors affecting river hydrodynamics and flood risk are climate change and urbanisation. However, the consideration of other factors may also be critical. Morphological change for example, is too often limited to the consideration of scour or silting at structures, and to the development of river maintenance schemes. For broad scale sediment transport studies, MIKE 11 may be sufficient. However, the MIKE 21 Flexible Mesh series is preferred for detailed design of flood defences or other structures, bank stability assessments and assessments of the effectiveness and impact of erosion control measures (hard or soft engineered) on river health and future habitats (for instance, fish spawning grounds). More advanced morphological modelling – including planform change – is possible using MIKE 21C (Curvilinear Grid). GROUND WATER AND PORUS MEDIA FEFLOW is our state-of-the-art integrated groundwater software package. It us used for the modelling of fluid flow, transport of dissolved constituents and heat transport processes in the subsurface. 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 modeling of contaminations from abandoned mines and for the simulation of geothermic energy systems.
