Abstract

A soil moisture measuring method of hillslope for Korean watershed is developed to configure spatial-temporal distribution of soil moisture. Intensive surveying of topography had been performed to make a digital elevation model(DEM). Flow distribution algorithms were applied and a measurement system was established to maximize representative features of spatial variation. Soil moisture contribution mechanisms of rainfall-runoff process have been derived. Measurements were performed at the right side hillslope of Buprunsa located at the Sulmachun watershed. A Multiplex system has been operated and spatial-temporal soil moisture data have been acquired. Relatively high correlation relationship between flow distribution algorithm and measurement data can be found on the condition of high humidity.

국내산지사면의 토양수분 시공간적 분포상황을 파악하기 위한 토양수분 측정법이 개발되었다. 대상유역을 정밀측정하여 수치고도모형을 구성한 다음 흐름분배 알고리즘을 적용하고 공간적 변화의 대표성을 최대화하기 위한 측정체계를 구축하였다. 토양수분이 강우-유출형성과정에 기여하는 기작을 표현하는 유도과정도 전개되었다. 측정은 설마천 유역의 법륜사 우측사면에서 수행되었다. 다중 측정망의 운영을 통하여 시공간적으로 변화하는 토양수분 자료를 획득하였다. 습한 조건에서 토양수분이 토양수분 추정 알고리즘과 비교적 높은 상관도를 보여주었다.
