Abstract
The objectives of the chapter are the identification of flash flood causes, their negative effects on environmental factors, and to study of modeling with advanced hydroinformatic tools. The authors analyzed the following models: DUFLOW, developed by the International Institute for Hydraulic and Environmental Engineering, Delft, The Rijkswaterstaat (Public Works Department), Tidal Water Division, The Hague, The Delft University of Technology The Netherlands; Hydrologic Engineering Center's Hydrological Modeling System runoff model, developed for the U.S. Army Corps of Engineers; Water Erosion Prediction Project, developed by USDA Forest Service, Agricultural Research Service, Natural Resources Conservation Service, Department of Interior's Bureau of Land Management, and Geological Survey from USA and MIKE11 by DHI, developed by Danish Hydraulic Institute, rainfall-runoff module. The authors conducted case studies of these models on different small hydrographic basins, located in west Romania, in the Banat region. Some possible measures to reduce the negative effects of flash floods are listed.
