Abstract

Stable operation of the dam and the river is directly related to the life and property of citizens, and hydrological observation data reliability is essential to the safety against disaster. Even though real-time data acquisition with high accuracy is needed for scientific and reliable water resources management, currently operating water gauges installed on the upper and down stream of dams or rivers are not easy to be calibrated or corrected on site to ensure higher reliability. K-water Institute has been operating an international accredited calibration laboratory for flows meters, rainfall and water gauges. Rainfall gauges are calibrated in the fixed standard room or on-site. However, due to the absence of on-site calibration procedure and system, on-site calibration for the water gauges are performed by an external agency. Therefore, a development of standard calibration procedure and system for on-site calibration of water gauges is needed to improve the reliability of observed hydrological data.

댐 및 하천의 안정적인 운영은 국민의 생명 및 재산과 직결되는 상황으로 수문관측 데이터 신뢰성 확보는 안전재난 대비에 필수 요소이며, 과학적이고 신뢰성 있는 수자원 관리를 위하여 수위 데이터에 대한 실시간 자료 확보와 신뢰성 있는 데이터가 필요하나, 현재 운영되고 있는 댐이나 하천 상하류의 수위계는 신뢰성 확보를 위하여 현장에서 검교정이나 보정 등이 쉽지 않은 실정이다. K-water연구원에서는 유량계, 우량계, 수위계에 대한 국제공인 교정기관으로 운영중에 있으며, 우량계는 표준교정실 및 현장교정시스템을 이용하여 표준실 및 현장교정을 하고 있으나, 수위계는 표준교정실에서 실내 교정만 수행하고, 현장교정은 현장교정 절차서 및 시스템의 부재로 현장 교정을 하지 못하는 실정이다. 따라서, 수위계를 현장에서 교정할 수 있는 표준교정절차서 및 시스템을 개발하여, 수문관측 데이터의 신뢰성을 향상시키고자 한다.
