Morphometry as a support for the study of floods in a western Mexican basin.

Abstract

The watershed have ideal characteristics to carry out environmental planning of the territory. The most important technique for the quantitative analysis of these characteristics is morphometry since it provides a response to the hydrological regime and reflects the topographic, geological and edaphological properties of the watershed. In this work, the morphometry of a watershed was determined to quantify the degree of vulnerability to flooding through physiographic and geomorphological parameters and through the hydrographic network. The results indicate that it is a watershed of intermediate to small size, due to its slightly widened shape it has a low probability of presenting intense and simultaneous rainfall, adding to this, the watershed presents a Kcvalue of 1.76 which indicates that the watershed is incapable to concentrate large volumes of water; This presents a drainage with a moderate level, which means that it is a watershed with a medium response to a precipitation event.
