摘要
小浪底水文站位于小浪底水利枢纽大坝下游4km处,下距西霞院反调节水库12km。两座水库的日常运用对小浪底水文站的测报工作影响较大,特别是西霞院水库的回水影响达到小浪底水文站测验断面以上,在高水位运用下,壅水影响严重。本文对西霞院水库各级水位对水文测报精度的影响进行初步分析。
The Xiaolangdi Hydrological Station is located 4km downstream of the Xiaolangdi Dam and 12km down stream from Xixiayuan Reservoir. Daily operation of the two reservoirs has a great influence on the Xiaolangdi Hydrological Station. Especially the backwater effect of Xixiayuan Reservoir reaches above the test section of Xiaolangdi Hydrological Station. Under high water level operation, Yongshui has a serious impact. This paper made a preliminary analysis of the influence of water level at different levels of xixiayuan reservoir on the accuracy of hydrological observation.
