Monitoring soil water content variability in the Cal Parisa basin (Alt Llobregat) with TDR. Experimental design and first results

Abstract

A small catchment on abandoned fields in the Pyrenees was monitored with the TDR method to evaluate the temporal and spatial variations of soil water content in relation with the hydrological response. The first results obtained over one year show a series of three periods of increasing wetness and three periods of decreasing wetness. Frequently saturated zones show high moisture values and stability over several rnonths, mesophile grassland zones show a wide and variable moisture range, and forested zones show the lowest soil moisture contents
