FLOOD RISK MANAGEMENT FOR SETTING PRIORITIES IN DECISION MAKING

摘要

Risk management as a tool for decision making has found more and more acceptance among scientists, and even for planners of flood protection systems. However, a shortcoming of this approach is that at present it only considers risk cost as management tool. It is at present the basis for most risk based approaches, which start with hazard maps, which can be prepared, in conjunction with Digital Terrain Models (DGMs) and geographical information system, if the necessary basic hydrological and topographical data are available. In fact, in many areas and in many countries it has become good practice to develop maps based on flood areas for different exceedance probabilities, with flood zoning as a preferred information for preparing the public for floods.
