Relaciones agua-suelo-vegetación.-Modificación de la distribución temporal y espacial de la precipitación por una cubierta arbórea de Pinus pinaster

Abstract

ABSTRACT Throughfall and stemflow volume generation was measured over 1 year period in a Pinus pinaster stand 9 years old. Throughfall was measured using 8 collectors in a fixed position connected to a tipping bucket rainfall gauge in a representative 10 x 10 m plot of the forest and stemflow was measured in three trees using a rubber ring around the trunk connected to a tipping bucket rainfall gauge. The two tipping bucket rainfall gauges was connected to a datalogger programmed to record data every 5 minutes. Of the 938.2 mm of total rainfall observed during the year-long period, stemflow accounted for 4 %, throughfall 72.7 % and there was a interception loss of 23.3 %. Throughfall intensity observed was 9.1% lower than rainfall intensity.
