我区现有的地下水长期观测井和专用观测井多数都设在灌区内,并且有很多位于河流、渠道、排水沟道附近。利用河渠附近观测井的地下水位动态资料进行地下水非稳定流计算,可以达到以下目的: (1) 确定含水层水文地质参数,如渗透系数K,给水度μ等。 (2) 予报河渠影响下的地下水位变化,确定河渠排水沟影响范围。
The existing groundwater long-term observation wells and observation wells in most of our area are located in irrigation areas, and many are located near rivers, channels and drainage channels. The calculation of unsteady groundwater flow using the groundwater level observation data of observation wells near the river can achieve the following objectives: (1) Determine the hydrogeological parameters of the aquifer, such as the permeability coefficient K and the water supply μ. (2) Report the change of groundwater level under the influence of river channel and determine the influence range of channel drainage channel.
