La medición de la infiltración de los suelos de la alta cuenca del Guadalquivir, Tarija, Bolivia

Abstract

Usually two considerations are defined to determine the elements of a water balance model. The first consideration includes the spatial limit conditions and the second the period of time. Both influence the reliability of the model and its results. The Model is also influenced by the availability of hydrometeorological data, the objectives of the study and hydrological abstractions that establish the degree of precipitation reduction. One of them is the infiltration that determines the amount of water that enters the soil and how much it drains superficially.

The lack of infiltration data is a problem to develop a water balance model in the upper basin of the Guadalquivir river in Tarija, Bolivia; the region is considered semi-arid and with short storms. The soils in the basin are shallow above the highly contorted bedrock in the surrounding hills and mountains, with deep lacustrine soils and glacial deposits.

This work studies the case of the upper basin of the Guadalquivir river. Describe the preliminary steps and the results in the development of infiltration data in a short period of time. These data will serve as the basis for hydrological and cartographic studies of the area.
