Abstract
유역에 대한 Horton의 차수비를 이용하여 Nash 모델의 매개변수를 지형학적 응답모델로 나타내었다.

응답함수의 최적화는 불완전 감마함수와 Rosso가 유도한 희귀방정식을 이용하였다.

본 방법의 적용성을 검토하기 위해 평창강 유역과 위천유역에 대한 실측치를 이용하였으며, 수문응답에 대한 재현성을 모멘트법과 비교하엿다.

분석결과 본 방법의 첨두유량, 도달시간, 그리고 수문곡선에 대한 재현정도가 비교적 높았으며, 미계측 유역의 유출해석이나 유역의 상사성 해석에 대해 중요한 수단을 제공할 것으로 판단되었다.
The phisical parameters of the Nash model were represented by a geomorphological response model using Horton's order ratio of a basin.

for the optimization of the response function, incomplete gamma function and Rosso's regression equation were used.

The application of this method was tested on some observed flood datas of

Pyungchang river basin and Wi stream basin, and predictions of hydrologic response wuch as the peak flow, time to peak and the hydrographs were compared with that of the Moment method.

The results show that the proposed method can be used for the runoff analysis of an ungauged basin and the analysis of hydrologic similarity.
