河床下切对东江岭下站水文测报的影响分析

Influential Analysis of Riverbed Undercutting to Lingxia Hydrological Station on Dongjiang River

通过岭下水文站的长期观测资料,分析了测验河段因河道采砂等人为因素导致河床大幅下切对水文要素的影响,提出应对河床不断下切情况下的水文测报、整编的措施。

Based on the long-term observation data of Lingxia Hydrologic Station, this paper analyzes the influence of the deep cut of riverbed caused by artificial factors, such as sand excavation, on the hydrological factors in the test reach, the measures of hydrological forecasting and reorganization under the condition of continuous riverbed cutting are put forward.
