Simplified Interception/Evaporation Model

It is known that at the event scale, evaporation losses of rainfall intercepted by canopy are a few millimeters, which often not much in comparison to other stocks water balance. Nevertheless, yearly number times filled and then depleted can be so large interception flux may become an important fraction rainfall. Many accurate models describe wet have been proposed. However, they require parameters difficult obtain, especially for large-scale applications. In this paper, simplified interception/evaporation model proposed, considers modified Merrian compute during spells, simple power-law equation dry spells. Thus, applied continuous simulation, according sub hourly data appropriate study both processes. shown derived linear storage model, also accounting antecedent stored volume, useful consider suggested approach. For faba bean cover crop, application procedure, providing reasonable results, performed discussed.
