Abstract

The subject of the paper is the selection of the number and location of rainguage stations among existing ones, which will be part of real-time data collection system, for the computation of mean areal precipitation and for use as input of real-time flow forecasting models. The weighted average method developed by National Weather Service was used to compute MAP. Two different searching methods were used to find local optimal solutions as a function of the number of rainguages. An operational rainfall-runoff model was used to determine the optimal location and number of stations for flow prediction.

본 연구의 목적은 실시간 자료수집 시스템의 일환으로서 어떤 유역에 존재하는 기존의 강우관측지점으로로부터 유역평균강우량을 산정할 때나 이를 강우-유출 모형의 입력치로 사용할 때 필요한 강우관측지점의 수와 위치를 선정하는 방법을 제시하였다. 유역평균강우량 산정방법은 미국 국립기상청이 제안한 가중치방법을 사용하였다. 강우관측지점 수에 따른 국부적인 최적위치선정은 서로 다른 두가지 방법으로 추적되었다. 유량예측을 위한 강우관측지점의 최적위치와 수를 결정하기 위하여 실제 실무에서 적용하고 있는 강우-유출 모형을 사용하였다.
