Analog-model studies of the effects of recharge wells along the Houston Ship Channel on potentiometric surfaces of the Chicot and Evangeline aquifers, Houston, Texas

Because of increasing concern about the continuing decline of water levels in the Houston area, an electric analog model was used to determine the effects on the potentiometric surfaces resulting from recharging water through wells along the Houston Ship Channel into the two major aquifers, the Chicot and Evangeline.

The model conditions simulated for this study are too complex to be described in detail. The upper model layer simulated the hydrologic conditions in the lower unit of the Chicot aquifer undifferentiated. The simulation included clay compaction and vertical leakage as well as transmissivity and storage. The lower model layer simulated the hydrologic conditions in the Evangeline aquifer which underlies the Chicot aquifer.
