The DIROM (Daily Irrigation Reservoir Operation Model) was modified to estimate amounts of water release from reservoirs, considering customaryirrigation water management practices, such as water supply for puddling and transplanting paddy rice from seeding beds and mid-season drainage. Theapplicability of the modified model was investigated by simulating amounts of water release from three study reservoirs: Hwamae, Ogi, and DoyaReservoirs. In terms of annual amounts of water release, the relative errors between the observed and simulated values in 2012 and 2013 ranged -26.20 %to 10.28 % and 4.90 % to 30.06 %, respectively; in case of reservoir water levels, the RMSE values ranged 0.45 m to 1.34 m and 0.40 m to 1.27 m,respectively. Also, it was revealed that the model provided better simulation results for monthly water releases than the original model. In addition, themodel presented better performance in simulating 10-day amounts of water release from April to June. However, the model had still significant errors inthe simulation results from July to September because the reservoirs were practically operated to adapt to water management circumstances. Finally, it isconcluded that the modified DIROM can estimate the amounts of water release from reservoirs, reflecting irrigation water management customs inpaddy-field districts. To achieve higher prediction accuracy of the model, it is necessary to incorporate practical reservoir operation rules into the model.
