Diseño experimental con lluvia simulada para el estudio de los cambios en la erosión del suelo durante la tormenta

Abstract

[ES] Se presenta el diseño de una experiencia realizada en campo con lluvia simulada para el estudio de los cambios que se producen durante la tormenta en ciertas propiedades superficiales (rugosidad y resistencia mecánica) y físicas (densidad aparente, conductividad hidráulica saturada, porosidad) del suelo. La experiencia se desarrolla en una zona agrícola semiárida del Sureste peninsular (Murcia), en parcelas experimentales de 4 m2 sobre dos tipos de suelos de diferente litología: coluvios calizos del Cuaternario y margas del Terciario. Los cambios en las propiedades estudiadas durante la tormenta fueron más evidentes en los suelos margosos que en los suelos desarrollados sobre coluvios calizos. Las relaciones entre estos cambios con la energía cinética de la lluvia fueron también más significativas en los suelos de margas. Los resultados indicaron que el diseño experimental fue válido para el estudio de los cambios en las propiedades de la superficie y del suelo durante la tormenta.ntif

[EN] The experimental design developed to study the changes within storm in some surface (roughness and shear strength) and physical soil properties (bulk density, saturated hydraulic conductivity and porosity) is presented in this paper. The experience was carried out with a rainfall simulator on experimental plots (4m2) in an agricultural area located in South East of Spain. Two soils with different lithology were selected: Tertiary marls and Cuaternary colluvial deposits. The results indicated that the experimental design and rainfall simulator were successful to study the changes occurred in the soil during the rainfall and kinetic energy was found to be the best indicator of the changes produced during the storm, especially on marly soils.

Este trabajo se ha realizado en el marco del Proyecto «Modelling Within Storm Erosion Dynamic» (ENV4-CT97- 0687) financiado por la Comunidad Económica Europea.
