dc.description.abstractThe Mantaro River valley is located between the west and is a major agricultural region. The valley is constantly affected by floods which cause extensive crop losses. The objective of this study is to assess the floodplain hazard with maximum discharges and at different return periods - River Analysis System). The methodology perform construction of a detailed digital terrain model (DT the frequency analysis, the DTM and the river geometry based on Quickbird and GeoEye satellite imagery used for modeling. The results have allowed us to analyze the floodplain with return period of 1, 10, 25, 50, 100 years, with high accuracy, attributed primarily to the digital terrain model. The results provide the technical basis for an early warning system in the Mantaro Valley. Important information was provided by the valley residents about the flood zones for perform prevention and mitigation purposes.en
