| Abstract:
Soil surface resistance increase quickly during the first three days after irrigation or rain. By explicitly incorporating surface resistance in simple equations, daily total evaporation estimation of a drip-irrigated olive grove was significantly improved. This increase in soil surface resistance could explain why observed cumulative soil evaporation is higher in locations with lower irradiance. In these locations surface resistance increased more slowly during the first days after irrigation. | |
