Análisis de riesgo de inundación con modelo bidimensional de la quebrada “Caupicho”

Abstract

In this article, the process of developing a flood risk map is outlined. The process begins with on-site recognition of areas affected by the overflow of the "Caupicho" stream, caused by significant precipitation events, based on the testimony of local residents. This is followed by the topographic survey of the analyzed stream and the surrounding areas. Once this information is digitized, a hydrological study is conducted to determine representative hydrographs for precipitation events. Simultaneously, the terrain characteristics (MDT) are entered into the IBER computational package to represent the computational domain, which will later allow us to generate a mesh that fits the digital terrain model (MDT). Subsequently, simulations are conducted to calibrate the model, comparing it with the depths of the channel observed on-site. Next, the flood risk map is generated, considering the depth and velocity, which are results obtained from the model.
