Floods Simulation on the Vedea River (Romania) Using Hydraulic Modeling and GIS Software: A Case Study

Extreme hydro-meteorological phenomena have become more frequent in recent years compared to the year 2000 Europe, including Romania. Flooding occurs from heavy rainfalls favored by natural and anthropogenic factors such as valley’s flat slope or settlements situated near river. Ţigăneşti Brânceni villages (from southern Romania) are no exception been affected floods many times. One of these events is that 2005, when flow reached 676 m3/s (a value 80 times higher than normal Vedea River) Brȃnceni. This paper aims present a simulation flood occurred during 3–6 July 2005 its impact on settlements, roads, land, using field observation (including some 2005), GIS software (ArcGIS), for simulations (HEC-RAS—Hydrologic Engineering Center River Analysis System), data Romanian National Institute Hydrology. Simulations were run HEC-RAS. The obtained flooded areas imported back into (Geographic Information System) used determine area covered water length roads. surface number buildings calculated different tools ArcMap. Results interpreted, commented on, with maps provided Water Administration. shows would be protected building levee along River. Significant losses can prevented, money saved.
