| Abstract:
The California Department of Water Resources and the University of California recently developed a weather generator application program “SIMETAW” to simulate weather data from climatic records and to estimate reference evapotranspiration (ETo) and crop evapotranspiration with the simulated data. In addition, simulated daily rainfall, soil water holding characteristics, effective rooting depths, and ETc are used to determine effective rainfall and to generate hypothetical irrigation schedules to estimate the seasonal and annual evapotranspiration of applied water (ETaw), where ETaw is the net amount of irrigation water needed to produce a crop. In this paper, we will discuss how the simulation model determines ETaw. | |
