RAINFALL INTERCEPTION BY A PINUS-SYLVESTRIS FOREST PATCH OVERGROWN INA MEDITERRANEAN MOUNTAINOUS ABANDONED AREA .2. ASSESSMENT OF THE APPLICABILITY OF GASHS ANALYTICAL MODEL

A set of 147 rainstorms each exceeding 1 mm bulk rainfall was used to validate the Gash analytical model of rainfall interception in a Pinus sylvestris forest patch overgrown in an abandoned Mediterranean mount ain area. The results seems to indicate that the Gash analytical model is sufficiently robust to be applicable in Mediterranean mountain con ditions for obtaining long-term total interception losses, and that pr ediction errors are in the same range as those obtained in earlier val idations of the model. In contrast, there is a marked difference betwe en observed and predicted values comparing individual events. (C) 1997 Elsevier Science B.V.
