Establishment of Wusong Datum System for Hydrologic Monitoring in Three Gorges Reservoir Area
摘要
Abstract
Considering the flat water-surface-profile area of Three Gorgers Reservoir (TGR) is highly close to the quasi-geoid, we carried out studies on calculations to correct the hydrologic benchmarks in the TGR area to the Wusong Datum system and tried to establish a conversion relation between the Wusong datum system and the 85 datum system. Based on large amount of water level measurements, using linear fitting method, we had refined the Wusong datum data of the hydrologic benchmarks in the upstream flat water-surface-profile area of The TGR and obtained some useful conclusions.关键词
