Description
The rainfall intercepted by an isolated olive tree was measured in a traditional olive-grove/ pasture system with a sparse canopy cover. Results from a two-year period of observations are presented. The data are then used to test models of the interception process in this type of agricultural system. Modelling was performed at the single tree level using the sparse-forest version of the Gash analytical model combined with two other methodologies: the wet bulb approach, to estimate the evaporation rate from the wet canopies of individual olive trees, and a newly developed procedure to estimate the canopy structure parameters. Good model performance was achieved at the storm level with model simulations within 1.5% of the observed value, clearly within the expected error of interception loss measurements. info:eu-repo/semantics/publishedVersion
