Calibración hidrológica de radares meteorológicos

Abstract

In recent years, the use of distributed models between rain and runoff by means of a geographic information system (GIS) tool has increased. However, the use of this tool in Mexico to describe the characteristics of a river basin with great detail has not been seriously considered, since the spatial density of rain gauges is not very high. This paper discusses the sensibility of several calibration methods for realistic estimates of rainfall using data from a radar located in a hill in conjunction with the Mexico City rain gauge network. These data are used as input in a distributed model. Results for the Mexico basin serve to establish a methodology that can be applied in other regions with scarce or no rain gauge instrumentation for flood forecast and prevention in high risk zones.
