ESTADO DEL ARTE DE MODELOS HIDROLÓGICOS E IDONEIDAD EN CUENCAS CON ESCASA INFORMACION

Abstract

In order to better understand and interpret the hydrologic cycle for a watershed, it is pertinent to first comprehend its spatial and temporal basin response. A hydrologic model aims to simulate the various rainfall-runoff processes and its production of flows. Presently, there is a wide variety of models based on the different hypothesis that include, among others, the physical and morphometric characteristics of the basin, as well as the availability of hydrologic information.

This work reviews and evaluates the state of the art of grouped and semi-distributed hydrologic models suitable for the Guadalquivir River Basin, in Tarija, Bolivia. An important challenge of this region that could condition the applicability of the models is the limited availability of hydro-meteorological and physical information. Among the 'grouped' models are the Témez and HBV, and among the semi-distributed models are the SACRAMENTO, WEAP, and HEC-HMS. The analysis of the bases of each model will be useful to determine in which situations it is convenient to use one or the other.
