The objectives of this study were to develop a hydrologic simulation model to estimate surface drainage for irrigation districtsconsisting of paddy and protected cultivation, and to evaluate the applicability of the developed model. The model consists of threesub-models; agricultural supply, paddy block drainage, and protected cultivation runoff. The model simulates daily total drainage asthe sum of paddy field drainage, irrigation canal drainage, and protected cultivation runoff at the outlets of the irrigation districts.
The agricultural supply sub-model was formulated considering crop water requirement for growing seasons and agricultural watermanagement loss. Agricultural supply was calculated for use as input data for the paddy block sub-model. The paddy block drainagesub-model simulates paddy field drainage based on water balance, and irrigation canal drainage as a fraction of agricultural supply.
Protected cultivation runoff is calculated based on NRCS (Natural Resources Conservation Service) curve number method. The Idongreservoir irrigation district was selected for surface drainage monitoring and model verification. The parameters of model werecalibrated using a trial and error technique, and validated with the measured data from the study site. The model can be a usefultool to estimate surface drainage for irrigated districts consisting of paddy and protected cultivation.
