IHACRES 모형을 이용한 평창강 유역 내 관측 유량자료의 평가 = Evaluation of Stream Flow Data Observed in the Pyungchang River Basin Using the IHACRES Model

다국어 초록 (Multilingual Abstract)

This study evaluated the runoff data collected at 12 stream gauge stations of the Chungjoo dam basin using the IHACRES model. Especially, the geomorphology-related parameters of the IHACRES model could be quantified base on the regionalization technique, which have also been applied many stream gauge stations of the Chungjoo dam basin. Summarizing the results is as follows. (1) The climate-related parameters of the IHACRES model , , and are found to be estimated and used uniformly over the basin. (2) The geomorphology-related parameters of the IHACRES model , , and are found to be estimated by considering the geomorphological parameters like the basin area, channel length, channel slope, basin slope through the regionalization based on the regression analysis. (3) Using the climate-related parameters applied uniformly over the basin and the geomorphology-related parameters estimated based on the regionalization procedure for each stream gauge station, a total of 12 stream gauge stations have been evaluated with their stream flow measurements. As results, the Sanganmi and Youngwal 1 stream gauge stations have been found to make high quality flow data, but Youngwal, Baekokpo, and Panwoon stations low quality flow data. On the whole, 12 stream gauge stations considered show large differences with their data quality, so a plan for securing more consistent data quality should be prepared imminently.

본 연구에서는 IHACRES 모형을 이용하여 충주댐 유역 내 12개 지점에 대한 관측유량자료에 대한 평가를 수행하였다. 특히, IHACRES 모형의 매개변수 중 지형특성 관련 매개변수를 지역화 기법을 이용하여 정량화하고, 이를 대상유역인 충주댐 유역의 여러 수위 관측지점에 적용하는 과정을 함께 수행하였다. 본 연구의 결과를 정리하면 다음과 같다. (1) IHACRES 모형의 매개변수 중 기후특성을 반영하는 매개변수인 , , 는 유역 전체에 동일하게 결정하여 사용할 수 있음을 확인하였다. (2) IHACRES 모형의 지형특성 매개변수인 , , 는 지형특성인자인 유역면적, 유로연장, 하천경사, 유역경사와의 회귀분석을 통한 지역화를 통해 적절히 추정할 수 있음을 확인하였다. (3) 유역에 대해 일관되게 적용된 기후특성 매개변수와 지역화 과정을 통해 추정된 지형특성 매개변수를 이용하여 충주댐 유역 내 12개 수위관측지점에 대한 관측유량을 평가하였다. 그 결과 상안미, 영월 1 지점의 유량 자료가 상대적으로 정도가 높은 것으로 확인되었고, 영월, 백옥포, 판운 지점의 경우는 유출자료의 품질이 상대적으로 낮은 것으로 파악되었다. 전체적으로 보면 고려된 12개 지점의 관측품질에 많은 차이가 확인되며, 따라서 보다 일관된 관측품질의 확보를 위한 방안의 마련이 시급함을 판단할 수 있었다.
