Simulated drawdown for selected well fields in the Ohio River alluvial aquifer

January 1, 1994

Drawdown due to pumping was simulated for three sites in the alluvial aquifer adjacent to the Ohio River by digital modeling techniques. Two well-field arrangements were used at each site. The initial well-field arrangement at each site consisted of three wells located in a line parallel to the Ohio River. The simulated wells were 350 feet (107m) apart and 500 feet (152m) from the river. Pumping was simulated at a rate of 1,500 gal min-1 (5,678 1 min-1) for 256 days. The second well-field arrangement allowed comparison of drawdown between the initial well-field arrangement and (a) wells located 350 feet (107m) nearer the river, (b) additional wells, located between the initial well field and the bedrock valley wall and (c) wells located on a line perpendicular to the river rather than parallel to the river. A verification procedure for the digital model based on observed aquifer response to a flood on the Ohio River is included as an appendix.
