Abstract

In this study, we tried to present a method for calculating the amount of regression using a watershed modeling method that can simulate the hydrological mechanism of water balance analysis and agricultural water based on watershed unit. Using the soil water assessment tool (SWAT), a watershed water balance analysis was conducted considering the simulation of paddy fields for the Manbongcheon Standard Basin (97.34 km2), which is a representative agricultural area of the Yeongsan river basin. Before evaluating return flow, the SWAT was calibrated and validated using the daily streamflow observation data at Naju streamflow gauge station (NJ). The coefficient of determination (R2), Nash-Sutcliffe Efficiency (NSE), Root-Mean-Square Error (RMSE) of NJ were 0.73, 0.70, 0.64 mm/day. Based on the calibration results for three years (2015-2017), the quick return flow and the return rate compared to the water supply amount for the irrigation period (April 1 to September 30) were calculated, and the average return flow rate was 53.4%. The proposed method of this study may be used as foundation data to optimal agricultural water supply plan for rational watershed management.

본 연구에서는 유역단위의 물수지 분석과 농업용수의 수문학적 매커니즘을 모의 할 수 있는 유역 모델링 방법을 이용하여 회귀수량 산정기법을 제시하고자 하였다. SWAT 모델을 이용하여 영산강수계 대표적인 농업지역인 만봉천 표준유역 (97.34 km2)에 대해 담수 논 모의가 고려된 유역물수지 분석을 실시하였다. 회귀수량 산정에 앞서, 나주 유량관측소의 일 유량 자료를 이용하여 SWAT을 검·보정하였다. R2, Nash-Sutcliffe Efficiency (NSE), Root-Mean-Square Error (RMSE)는 각각 0.73, 0.70, 0.64 mm/day으로 분석되었다. 3년 동안(2015~2017) 모의 결과를 토대로 관개기간(4/1~9/30)에 대한 신속 회귀수량과 공급량 대비 회귀율을 산정하였고, 평균 53.4%로 분석되었다. 본 연구에서 제시한 유역 회귀수량 모델링 기법은 향후 합리적인 유역물관리를 위한 최적 농업용수 공급방안에 대한 기초자료 구축에 활용될 수 있다.
