The concept of decentralized flood protection measures is based on the idea of localization and usage of the capability of headwater areas of a flooded catchment to retard runoff as early as possible and at several places at the same time by means of flood detention basins with minimum environmental impact. Flood protection management is discussed on a project planning level. A system of multipurpose flood protection self-regulated dams with flood detention basins is analyzed as the measures for mitigation of flood events. The method to justify a site selection of self-regulated flood dam and other parameters of the dams, providing minimization of impact on the environment have been developed. Some results of the method application in GIS environment to prove there robustness are presented. (C) 2016 The Authors. Published by Elsevier Ltd.
