Floods and societyter levels of lakes, reservoirs, aquifers and estuaries. Experience demonstrates that flood dangers can be alleviated but can’t be completely eliminated. Coping with floods refers to all measures which society can undertake to alleviate impacts of floods. Three types of floods occur: natural floods,

Historical development of flood analysis methodswell as for the efforts to understand the laws that govern flood processes. At the same time, improvements in data measurement techniques and processing methods, also resulting from advances in related disciplines, have to be considered because they largely affect the evolution of hydrologic modelin

Hydrometeorological data collection networkso provide early warning of impending floods or for providing information on management of water control systems. Areas discussed include data requirements for major river floods; flash floods; snowmelt floods; and water management information. Collecting hydrometeorological data manually; using auto

Rainfall frequency analysis for flood designthe analysis of extremes at a single site, the contribution discusses the “pooling” of data from several sites and the derivation of depth-duration-frequency relationships. The treatment of spatial (i.e. intersite) and temporal (i.e. inter-duration) dependence is seen to be relevant to achieving con

Determination of flood characteristics by physically-based methodsclude single event models in which flow characteristics are estimated only during the flood event, and continuous event models in which flow characteristics are determined continuously during wet periods and dry periods.

Determination of flood characteristics using systematic, historical and paleoflood datacal data and paleoflood data in flood frequency analysis has been recognized. In this chapter, the basis and applications of historical and paleoflood data to increase the flood data base are reviewed along with a description of the methods of flood frequency analysis where systematic, historical, a

Regional flood estimation methodsative role played by spatial and sampling variability of the parameter estimate. At the first level, the flood distribution is identified and its shape parameters are estimated. Spatial variability is much smaller than sampling variability and the homogeneity hypothesis can be made. At the second le
