主 题:Manas River Basin water balance numerical simulation reservoir regulating groundwater
摘 要:Reservoir regulation and storage is the main approach to alleviate the water pressure caused by the uneven spatial and temporal distribution of surface water resources in arid areas of northwest *** the regulation and storage of the reservoir affect the conditions of recharge and discharge of groundwater,the process of regional surface-groundwater transformation tends to be *** Manas River basin that lies on the northern slope of Tianshan Mountain in Northwest China was taken in this study as a case.A numerical model of groundwater in basin plain area was established,and the influence of reservoir regulation on groundwater level was *** results showed that the total recharge of groundwater in the study area was 75.539 million m3,the total discharge of groundwater was 82.66 million m3,and the groundwater in the study area was in a negative equilibrium state,with a difference of-69.27 million *** water balance method was used to verify the *** total recharge of groundwater was 74.34 million m3,the total discharge of groundwater was 80.726 million m3,and the calculation result of the numerical simulation of the supplementary displacement was 63.82 million m3,basically consistent with the calculation result of the water balance *** reservoir storage method has obvious changes to the groundwater level around the *** simulation results of groundwater numerical model showed that when the reservoir was in normal operation,the leakage of the reservoir was 27.35 million m3;when the reservoir was operated at low water level,the leakage of the reservoir was the smallest,13.47 million *** reservoir has the largest amount of leakage of 41.85 million m3 when operated at water storage *** the reservoir was operated at the lowest water level,the groundwater level around the reservoir was declining compare to the normal operating water *** maximum drop of the groundwater observation well was 2.1 m,and the maxi
