Protocolo para medir la infiltración in subcuencas del Rincón de la Vittoria y del monte de la Alta Cuenca del Guadalquivir

Abstract

Hydrological abstractions such as infiltration, percolation, evaporation, transpiration and interception are fundamental parameters in the process of simulation and modeling of the water balance in a basin. These parameters allow us to analyze and determine the degree of reduction experienced by precipitation from the atmosphere to reach the earth's surface and eventually become runoff. However, the degree of knowledge of these abstractions is the product of a research process that will reduce the uncertainty that accompanies the results of all hydrological modeling.

This work describes the experimental protocol developed for the sub-basins of the Vittoria corner and the mountain stream belonging to the upper Guadalquivir river basin in Tarija, Bolivia. The main objective of the protocol is to obtain the infiltration parameters and soil types that make up the study areas. Minidisc infiltrometers were used to collect data in the field at more than 200 points distributed in the experimental sub-basins. The results have allowed to describe, characterize and elaborate soil maps and hydraulic characteristics such as infiltration that will be used in the modeling of the water balance of the upper Guadalquivir basin
