Rainfall interception by a Pinus sylvestris forest patch overgrown in a Mediterranean mountainous abandoned area .2. Assessment of the applicability of Gash's 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 mountain area. The results seems to indicate that the Gash analytical model is sufficiently robust to be applicable in Mediterranean mountain conditions for obtaining long-term total interception losses, and that prediction errors are in the same range as those obtained in earlier validations of the model. In contrast, there is a marked difference between observed and predicted values comparing individual events. (C) 1997 Elsevier Science B.V.
