Abstract
As a kind of vital water resources exploitation mode, riverside pumping has the important advantage of maintaining the stability of water supply and purifying surface water quality. It is of great significance to estimate the pumpage from a riverside well for the sustainable utilization of water resources in the area. In this article, the method of image and Girinskii's potential function are used to derive the pumpage. A case study in the Jamusi City shows that the pumpage from a riverside well varies from 9000 to 15000 m3/d. The sensitivity of factors (h0, K, Smax and rw.) is analysed, indicating that the influence degree from large to small is h0, K, Smax, and rw. Besides, h0, K, Smax are far greater than rw. It is hoped that this paper can provide some theoretical reference for the rational utilization of groundwater in the areas near the rivers.
