국내 중산간 이수취약 농업지역의 대체용수확보를 위한 강우-유출량 추정 연구

Abstract

Advanced research is being conducted to develop rainfall-runoff based alternative agricultural water systems for mid-mountain upland farming areas, where stable water supply remains a persistent challenge. This study aims to evaluate the practical applicability of the system by identifying irrigation-vulnerable upland farming areas across the country and estimating daily rainfall-runoff in those areas to assess the feasibility of system implementation. Irrigation-vulnerable upland farming areas cover a total of 3,534.4 ha, comprising 939 agricultural sites. Among these, Gangwon-do was found to have the largest number of sites (237). Even when applying an elevation criterion based on 100 m intervals, the rate of area reduction remained relatively low. Additionally, the average runoff in the target areas was estimated at 1.99 mm/day per unit watershed area and 15.71 mm/day per unit irrigated field area. This study provides baseline data for prioritizing the implementation of alternative agricultural water systems. Future research should assess the applicability of these systems in changing agricultural environments by estimating future water availability under climate scenarios.
