15.3 The Hydrologic Cycle A confined aquifer is bounded on top and bottom by layers impermeable to water. Water in these aquifers is stored under high pressure and recharged by rain and surface water from a geologic recharge zone. An impervious confining layer is called an aquiclude. A ...
Concurrent declines in the potentiometric surfaces of unconfined aquifers and underlying confined aquifers are frequently assumed to be due to leakage of water from the former to latter, especially where the confined aquifer is much more heavily exploited and the hydraulic gradient is downward. It has...

A confined aquifer is bounded top and bottom by impermeable formations. However, in some areas, where the confined aquifer is subject to recharge, it is basically a phreatic aquifer. Sign in to download full-size image Figure 1. Schematics of phreatic and confined aquifers. There are several ...
Groundwater outburst has an impartible relationship with geological structures such as water-conducting faults, which are widely distributed in north China. In order to study the seepage property and mechanism of water outburst from the faults above a confined aquifer in the coal mining, the simulat...
