To effectively implement the integrated water management policy outlined in the National Water Management Act, it is essential to analyze agriculturalwater supply and demand at both basin and water district levels. Currently, agricultural water is primarily distributed through open canal systems andcontrolled by floodgates, yet the utilization-to-supply ratio remains at a mere 48%. In the case of agricultural water, when analyzing water balancethrough existing national basin water resource models (K-WEAP, K-MODISM), distortion of supply and regression occurs due to calculation ofregression rate based on the concept of net water consumption. In addition, by simplifying the complex and diverse agricultural water supply systemwithin the basin into a single virtual reservoir, it is difficult to analyze the surplus or shortage of agricultural water for each field within the basin. There are limitations in reflecting the characteristics and actual sites of rural water areas, such as inconsistencies with river and reservoir supply prioritysites. This study focuses on the development of a model aimed at improving the deficiencies of current water balance analysis methods. The developedmodel aims to provide standardized water balance analysis nationwide, with initial application to the Anseo standard watershed. Utilizing data from 32facilities within the standard watershed, the study conducted water balance analysis through watershed linkage, highlighting differences andimprovements compared to existing methods.
