Abstract
The objective of this research is to analyze the risk of flooding in the Pumahuasi - Huamancoto sector, district of Daniel Alomía Robles, department of Huánuco. Floods are a devastating event that causes serious consequences for people, affecting the productive zone, the urban and natural area, the environmental impact is direct since the flooded area is difficult to recover, it also affects the fauna because they are displaced from their habitat which leads to migration; the social impact is given because the affected inhabitants may choose to stay in place and rebuild their homes, experiencing a financial burden; the economic impact is that these events affect the district since the productive chain is broken. To determine the risk, geotechnological tools were used such as: HEC-RAS, for hydraulic modeling; ArcGIS, a well known Geographic Information System for the processing and representation of flood risk. As a result, it is shown that, in flood risk mapping, the predominant unit is high risk. The vulnerability analysis, developed based on the established methodology, indicates that there are crop lands with very high, high and medium levels of vulnerability to the occurrence of river flooding.
