Abstract
A soil moisture measuring method for a hillslope of Korean watershed was developed to configure spatial-temporal distribution of soil moisture. Intensive surveying of topography had been performed to make a refined digital elevation model(DEM) and the hydrological interpretation from flow distribution algorithm was incorporated through reverse surveying. Moreover, A long term measurement system was established to maximize representative features of spatial variation of soil moisture and operated from October 19 to 21, 2003. TDR(Time Domain Reflectometry) with a multiplex monitoring system has been operated for accurate measurements. Measurements were performed at the right side hillslope of Buprunsa located at the sulmachun watershed. The data of temporal and spatial soil moisture variation by rainfall event were collected and the variations of soil moisture were well captured.
국내산지사면의 토양수분 시공간적 분포상황을 파악하기 위한 토양수분 측정법을 개발하였다. 대상유역을 정밀 측량하여 수치고도모형을 구성한 다음 흐름분배 알고리즘을 적용하였고 역측량을 통한 내상 유역의 흐름분배 알고리즘의 유의성을 판단하였다. 이를 통한 공간적 변화의 대표성을 최대화하기 위한 장기 모니터링 시스템을 구축하고, 10월 19일부터 21일까지 연속적인 모니터링을 실시하져다. 토양수분의 정확한 측정을 위해 TDR(Time Domain Reflectometry)를 이용하였다. 측정은 설마천 유역의 범륜사 우측사면에서 수행되었다. 강우사상에 의한 시공간적 토양수분의 변화 자료를 획득하였고, 강우사상에 의한 토양수분의 변화를 확보할 수 있었다.
