| Abstract | To prepare for agricultural droughts, the potential discharge to the water supply of irrigation facilities during drought periods is important. Using the MODSIM (Modified SIMYLD) model, water balance networks that consider irrigation facilities were designed for the Geum River Basin, and the potential discharge to the agricultural water supply of irrigation facilities were evaluated by running the model using data for 36 years (1967-2002). It was found that agricultural water deficiencies occurred during the drought years more than in the other years. The agricultural water deficiencies in 1994, 1995, and 2001, the representative drought years, were 745.8 million m, 661.1 million m, and 696.8 million m, respectively. The average potential discharge to the water supply of the sub-basin was 99.1 % in the cases of municipal and industrial water, and 84.4 % in the case of agricultural water. The potential discharge to the water supply in 1994, 1995, and 2001 were 74.8 %, 79.2 %, and 77.9 %, respectively, which are lower than those of the other years` sub-basin average. In the analysis of the contribution of each irrigation facility, the contributions of pumping stations and diversions were calculated as 32.5 %, and of culverts and wells, 4.0 %. During the drought periods, the pumping stations and diversions contributed to a certain level. |
