The performance of present hydrological observation system under heavy rainfall is often questioned. Newly developed equipment used in remote hydrological observation internationally give further problems on their integration with present system. Therefore, there is a need for inspection/calibration techniques for all hydrological observation system. To improve the dependability and accuracy of hydrological system, data processing and field operation standard are two most important issues. Water Resources Agency commissioned a project ”The preliminary study of calibration techniques and establishing calibration environment for hydrologic measuring instruments under the characteristics of Taiwan.“ Suggested to develop the improvement of the hydrological measuring quality of calibration techniques under heavy rainfall, including inspection and calibration of rain gauge, remote sensing surface radar velocimeter in 2012. For extending the former project, Water Resources Agency plan a two-years project, and the first-year project in 2013 completed initially the development and building calibration environment of the rain gauge under heavy rainfall, the calibration techniques of remote sensing surface radar velocimeter, hydrological observation instrument operation/instrument calibration technology seminar and to assess the WRA other hydrological instruments calibration demand. Our team will focus on hydrological observation instruments under heavy rainfall, propose standard operating procedure and management systems on site, and improve the quality and reliability of hydrological observation under heavy rainfall significantly.強降雨水文觀測檢驗校正Heavy RainfallHydrologic ObservationInspection and Calibration
