Abstract

A methodology to resolve a TOPMODEL problem has been suggested, which is associated with the spatial distribution of soil moisture behaviour in a runoff mechanism. A procedure to integrate the spatial information of saturation deficit in the TOPMODEL reflects the connectivity of saturated area in a watershed. The developed algorithm includes an improved basis in tracing the runoff path without increasing the number of parameters. The performance of the developed algorithm has been tested to an upland subwatershed, namely Dongok, which is the IHP watershed located at Wichon, Korea. Comparing with the original statistical version of the TOPMODEL, it has been found that the suggested algorithm can relax an overestimation of peak rate in the runoff simulation.

본 연구는 토양수분의 공간적 분포를 고려하는 과정에서 TOPMODEL이 가지고 있는 구조상의 문제를 해결하는 방안을 제시한다. 포화초과유출을 모의하는 기존 TOPMODEL은 유출모의시 유역내 포화부분의 공간적인 정보를 반영하는 과정에 있어 포화면적의 연결성을 고려한 유출 알고리즘의 개발로 발전되었다. 개발된 알고리즘은 TOPMODEL의 매개변수를 증기시키지 않고 개선된 유출경로 추적의 근거를 제시함으로써 모형의 합리성과 적용성을 제고시켰다. 본 연구에서 개발된 포화면적 연결모형과 기본적인 통계적 입력모형형태의 TOPMODEL을 국제수문개발계획 대상유역인 위천유역내의 동곡소유역에 적용한 결과 본 연구에서 개발된 포화면적 연결모형이 다른 두 모형에서 발생하는 모의시 과도첨두유량계산의 문제를 해결할 수 있었다.
