초록

정확한 강수량의 측정은 댐 및 하천의 운영, 농어촌 및 산림녹화, 안전관리 등 사용분야가 광범위하며, 재난재해를 대비하고 강우발생시 경제적인 효과를 얻기 위해서 필요하다. 본 연구에서는 집수형 강수량계의 성능을 분석할 수 있는 통합검증시스템에 의한 강수량계 종류별 특성시험을 실시하였다. 전도형 강수량계는 0.0041 mm, 무게식 강수량계는 0.0045 mm, 표면장력식 강수량계는 0.0039 mm으로 불확도가 산출되었으며, 강수량계의 종류 및 특성에 따른 불확도는 크게 다르지 않음을 알 수 있었다. 이러한 특성시험을 통하여 강수량계 종류에 따른 기상관측 및 수문관측 데이터의 신뢰성을 확보하고자 하였다.

Precipitation has a wide range of applications, such as the management and operation of dams and rivers, supply of dranking water for urban and industrial complex, farming and fishing, forest greening, and safety management. In order to prepare for disasters and to obtain economical effects in case of flood damage, it is necessary to measure accurate precipitation. In this study, we carried out the characteristics tests for various types of rainfall gauge using integrated verification system, which can analyze the performance of collective type rainfall gauge. The uncertainty for tipping bucket rain gauge was 0.0041 mm, where weight type and surface tension type was 0.0045 mm and 0.0039 mm respectively. Therefore, the uncertainty according to the type and characteristics of the precipitation system is not significantly different. The uncertainty is also influenced greatly by the resolution.
