Water lain deposits may exhibit anisotropy on the horizontal plain (X,Y if looking down from above). Groundwater Hydraulics. Daene C. McKinney. Summary. Confined Aquifer Flow. Continuity Equation.

Aquifers. ~ Any underground layer of rock or sediment that holds water.. ~ They can range in size from a small underground patch of permeable material to an area the size of several states.. Aquifers. By: Lauren Cameron. Introduction. Partially penetrating wells:. aquifer is so thick that a fully penetrating well is impractical. Increase velocity close to well and the affect is inversely related to distance from well (unless the aquifer has obvious anisotropy). Groundwater Hydraulics. Daene C. McKinney. 1.
