Tripp Winters . Anisotropy is a common feature in water laid sedimentary deposits (fluvial, . clastic. lake, deltaic and glacial outwash). . 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.

Characteristics of Aquifers. t. ests and tests in well fields. •Aquifers may be pumped at variable discharge rates either deliberately or due to characteristics of the pump. . •Aquifers can be pumped step-wise (always pumped but pumping rates vary) or may be pumped intermittently (not always pumped and pumping rates can vary). .
