![]() ![]() In some areas light detection and ranging (LIDAR) data provided by water agencies could be used. Topographic agencies contributed digital elevation models at several resolutions. The data came from several subnational, national, and European agencies. For vector data these issues are relatively easy to handle however, projecting raster digital elevation models and even scanned topographic maps proved to be a time-consuming effort. In total, six different coordinate systems had to be integrated into a single reference system. The type of data needed was soon defined, but data availability, quality, model, format, scale, and coordinate systems varied greatly. Data RequirementsĪn important issue in the study was the data on which the hydrologic and economic models were to be based. The bound version of the atlas and a CD-ROM version with 41 double maps were published in March 2002. ![]() The maps should also depict the monetary values potentially at risk during an extreme flood event.Ī team of hydrologists, economists, and GIS experts was commissioned to carry out the study and produce maps at a scale of 1:100,000 to be published as an atlas. Improving awareness through the preparation of hazard and risk mapsīefore any technical measures were taken, the committee commissioned a study to produce maps showing the extent and the inundation depths of a 10-year flood, a 100-year flood, and an extreme event.Reducing extreme flood stages up to 70 cm by 2020.Reducing damage risks up to 25 percent by 2020.The action plan mentions four targets that should contribute to that objective: It was agreed to reduce damage risks by 25 percent within a 25-year period. In 1998 the ICPR enacted the Action Plan on Flood Defense. The Rhine countries are organized in a multilateral committee, the International Committee for the Protection of the Rhine (ICPR), based in Koblenz, Germany. It was recognized, though, by all affected countries that the level of safety provided by this system may not be sufficient for extreme events when floodwater levels exceed the levee height or when levees fail. Recent devastating floods in the 1990s caused considerable damage and are well remembered by the responsible agencies as well as the local population.Īn extensive system of levees in France, Germany, and the Netherlands, built and maintained during the last few decades, provides for a certain level of protection. A long historical record of flooding is documented in the archives. From its source in the Swiss Alps the Rhine flows through Lake Constance and defines the border between France and Germany before it finally flows into the Dutch North Sea. Approximately 10.5 million people live within the wider flood prone areas, which have undergone a tremendous man-made change. Many important industrial production sites are concentrated along the river course, among them a lot of facilities producing hazardous chemicals. In addition, water from Belgium, Italy, and Luxembourg flows to the Rhine. Its borders are shared by no less than five countries-Austria, France, Germany, the Netherlands, and Switzerland. The river Rhine has been one of Europe's most important waterways for centuries. Inundation depth map-shades of blue show depth classes, green and red lines show the 10- and 100-year flood extent (taken from Atlas 2001: Atlas der Überschwemmungsgefährdung und möglichen Schäden bei Extremhochwasser am Rehin, modified). © 2020 FloodMap.Through Five European Countries-A Long River With a Long History of Flooding Rhine Flood Hazard Mitigated With the Help of GIS Notes:Before using this Flood Map application, please note that for various technical or non technical reasons the application is not guaranteed free of bugs or inaccuracies. Negative elevation means depth below sea level.ĭata Sources: Mazpzen, TNM, SRTM, GMTED, ETOPO1 The elevation layered on the map is in meters and is from sea level. By setting negative elevation, Bathymetry study is also possible.We also think that it can help in planning irrigation system and water management.It can help to perform elevation analysis of an area for any purpose like city/town planning, new construction etc.Global Warmin and Sea Levele Rise are the effects of Climate Change.Effect of sea level rise or sea level change can be seen on the map.It can also provide floodplain map and floodline map for streams and rivers.Heidelberg, Germany Flood Map can help to locate places at higher levels to escape from floods or in flood rescue/flood relief operation.Heidelberg, Germany Flood Map may help to provide flood alert/flood warning if flood water level at certain point is rising.Heidelberg, Germany Flood Map may be useful to some extent for flood risk assessment or in flood management, flood control etc. ![]()
