South Boulder Creek, in Boulder, Colorado, USA, is currently at the centre of a local floodplain controversy. Due diligence research for a major land acquisition in the South Boulder Creek watershed by the University of Colorado identified potential flooding in an area known as the West Valley that were not identified in the regulatory Flood Insurance Rate Map (FIRM). Because the West Valley was not identified as being in the 100-year floodplain, it was developed without flood protection measures. With the discovery of flood prone areas that were not identified in previous studies, public confidence in the regulatory floodplain was lost. |
| Saving lives in Songhua, China | ^ |
53.5 million People live in the Songhua River Basin area which covers an area of 557,000 km2. The area is frequently exposed to severe flooding and this has a serious impact on the population and their livelihood. Recent major flooding occurred in 1991, 1994, 1998 and 2003. Furthermore the major provincial capitals of Harbin and Jilin are often hit severely by the flood and the oil-fields near Qiquar are regularly threatened too.
DHI Water & Environment, Mott Macdonald (UK) and the Institute of Water Resources and Hydropower Research in China have been awarded a major contract by the Songliao Water Resources Commission (SWRC) to develop a state-of-the-art flood management system for the Songhua River Basin.
The system will provide easy access to all relevant flood information including historical and real-time data, modelling results, damage assessment information, scenario analysis, reservoir management and optimisation and information selected for dissemination of flood warnings.
The modelling components in the system are built around the well known MIKE 11 and MIKE FLOOD engines, utilising MIKE FLOOD WATCH for real-time forecasting of water levels at many locations including cities of Jilin and Harbin. The forecasting system will also include the operation of the major reservoirs in the catchment.
An important component in the project is the comprehensive training program, where the local flood management engineering staff is trained in advanced modelling and decision-support technologies.
Holistic flood management where a large number of influencing factors may be evaluated and measured against each other well before they are implemented will not only preserve property, but also has the potential to save lives.

| Decision Support System controls the Three Gorges Dam | ^ |
Twelve of the planned 32 hydropower units are now in operation and all other structures have been completed, including the 67 spillway gates, ship locks and the sediment and debris gates.
An inflow forecasting system for the dam has now been developed by DHI Water & Environment in cooperation with the Yangtze River Commission. This system will provide decision support for the operation of the dam, so that the power production can be maintained while ensuring sufficient storage to control river water levels downstream and avoid flooding.
The inflow forecasting system for the Three Gorges Dam is linked to a network of real-time rainfall and river stations providing data every 15 minutes to a central database. The forecasting process is controlled by the real-time decision support system MIKE FLOOD WATCH, which runs automatically at regular intervals. Based on this forecasts and recommended gate operations are issued.
By the end of 2006 the level of the reservoir will be raised and again in 2009 once the dam and all power units have been completed. The flood retention volume will at that time be significant. This water can be released whenever the forecasting system predicts a major inflow event. As a result the dam can be used as a buffer which can prevent or at least reduce the risk of floods, which for centuries has been a threat to the huge population along the Yangtze River.

City of Ballerup, Denmark, Integrates Urban Water Modelling and GIS |
^ |
Ballerup is a suburb to Copenhagen, the capital of Denmark. The population is 47,000 and the area is approximately 6,000 acres. The City is responsible for a sewer network consisting of 120 miles of pipes, a storm drainage network with more than 100 miles of pipes and a water distribution network, which includes 200 miles of pipes.
Two important tools used in the planning and management of the water and collection systems are GIS and simulation models. Until recently, these tools were more or less isolated islands with data transfer taking place through cumbersome file transfers.
Simulation Models
Simulation models for water, storm water and waste water are extensively used for analysis of operational problems such as flooding, sewer overflows, etc. Models are also crucial tools for planners, who need to identify future bottlenecks and find the most cost effective solutions to ensure adequate capacity of the infrastructure, when new areas are urbanized. Simulation models need information about the physical properties of the pipe network - pipe sizes, materials, hydraulic structures, pumps, valves, etc. Such information is typically managed in an asset management system, which is frequently another isolated island in the IT systems of the city or utility.
GIS connects the Islands
The open architecture of ArcGIS makes it an ideal connectivity tool for the many applications that are used in the management of data related to urban water infrastructure. Using the Geodatabase as the central data repository, the different types of applications can easily exchange data and combine information that originates from separate applications. The new modelling tool MIKE URBAN makes full use of this openness.
Modelling and GIS
MIKE URBAN is a comprehensive tool-set for modelling of urban water distribution and collection systems. It is unique by being fully integrated with ESRI ArcGIS components, which means that all the management and display of spatial data takes place in a GIS environment, which is immediately recognizable by ArcGIS users. The GIS components are fully integrated with a wide range of numerical simulation engines for water and collection system networks.
Connecting the IT Islands
MIKE URBAN uses the Geodatabase as repository for all network related data. The data model is open and documented and the data can be accessed and even managed through other GIS applications. At the same time, MIKE URBAN can obviously use whatever other relevant data that the user may be storing in her GIS system, e.g. land use data, aerial photographs, digital elevation data, etc as background information for the modelling.
Powerful Visualization
Visualization of the pipe networks is made easy with the facilities available in 3D Analyst. Quality assurance is always a major part of the model building process and visualizing the network is a big time-saving technique.
MIKE URBAN combines the traditional GIS visualization techniques with powerful dynamic result visualization based on DHI’s MIKE Objects components. The resulting animations of flows and water levels are essential for the interpretation, comparison and presentation of the simulation results.
Simulating Climate Change
In addition to the traditional uses of modelling, Ballerup also uses models in order to prepare for the potential consequences of climate change. In Denmark, it is expected that rainfalls will become more intense in the coming decades and this may of course lead to increased flooding in the urban areas. MIKE URBAN includes long term simulation tools, which are well suited for the analysis of the effects of changes in rainfall patterns in terms of statistical quantification of a range of possible scenarios.
2D Flood Simulations
In addition, MIKE URBAN can be linked with a 2D overland flow model, which is capable of simulating the detailed flow pattern above the ground. This may in many cases be the only way to get a realistic impression of the likely flooding scenarios. The overland flow model receives overflows from the underground network, routes the water dynamically and allows it to re-enter the drainage network when and where the capacity is available.
The results from the 2D simulations can of course also be visualized dynamically within the GIS environment.

"..the MIKE system proved to be extremely user-friendly and efficient ....providing more time to consider the science"
This enthusiastic endorsement was made by Oliver Jones at the recent DHI Software User Group Meeting (UGM) in the UK. Oliver is working toward his PhD at the University College London (UCL) and has, in the course of his studies, been using many different modelling tools. His collaboration with DHI and use of their technology has enabled him to focus much more on the scientific applications rather than monotonous modelling tasks - read full story at http://www.dhisoftware.com/general/News/FM_UKwaters/index.html

Watershed Models – MIKE SHE |
The recently published book Watershed Models, 2005 (Eds. V.P. Singh & D.K. Frevert, CRC Press. ISBN: 0849336090) includes a full chapter on the MIKE SHE model. This chapter includes an up-to-date description of the MIKE SHE as well as a comprehensive list of different applications. These applications range from river basin management and groundwater modelling to the analysis of the effects of land-use change and anthropogenic effects.
