Abstract
[Resumen] En una pequeña cuenca bajo explotación de dehesa se investiga la generación de
escorrentía superficial a distintas escalas. Ello incluye experimentos con lluvia simulada en microparcelas, mediciones del flujo superficial en eventos en 17 parcelas abiertas y una parcela. cerrada, y la producción de caudal de la cuenca y una subcuenca. Los coeficientes de escorrentía de las escalas consideradas se agrupan en dos conjuntos: valores bajos para la cuenca y subcuenca, y valores altos a escala de pedón y ladera. Los resultados demuestran que gran parte de la escorrentía producida en las vertientes se infiltra después en las zonas coluviales y fondos de valle. Además indican la importancia de estudiar varias escalas para
entender los procesos hidrológicos que operan en cuencas.
[Abstract] In a small catchment under the so-called dehesa landuse system, the production of surface runoff is investigated at different scales. This includes experiments with simulated rainfal1 at micro-plots, event-based measurements of overland flow at 17 open plots and 1 closed plot, and discharge production of the catchment and subcatchment. The runoff coefficients of the considered scales form two groups, with low values for the catchment and sub-catchment and high values for the microplots and hillslope plots. The results show that large part of runoff produced at the slopes is infiltrated afterwards at colluvial sites and the valley floors.Furthemore, they indicate the importance of studying at various scales in order to understand the hydrological processes operating in catchments
