Abstract

Rice yields at the Sangker river basin in western Cambodia are simulated by a coupled model of the distributed hydrological model WEB-DHM and the rice growth model SIMRIW-rainfed. The results are validated by in-situ statistical data and FAOSTAT. Then, future rice yields are also simulated by using GCMs outputs. In addition, a simple irrigation model is introduced into the coupled model. By using this model, rice yields in consideration of climate change and irrigation are assessed.<br>In this study, effectiveness of irrigation in this river basin is shown for both of the present and future climates. The results showed that, by constructing irrigation facilities, a stable rice yield can be obtained even if no yield is obtained at rain-fed paddy fields. Also, this study showed that a variation of future rainfall pattern will affect a variation of rice yield.
