Abstract
The effluent from drains in a saline water aquifer, being recharged with fresh water, consists of a mixture of salt and fresh -water. A Hele-Shaw model study was conducted to determine the rate of quality change of drain effluent for various conditions of drain spacing, thickness of aquifer, permeability , and recharge rate. Three aquifer conditions were studied: 1. A uniform aquifer, 2. A 13 layered aquifer (top layer 12 times as permeable as the bottom), 3. A layered aquifer (bottom layer 6 times as permeable as the top). Results are presented in the form of dimensionless chars, containing the variables drain spacing, thickness of aquifer, permeability, recharge rate, and effective porosity. The concentration of the effluent at any time was found to be: 1. inversely related to the recharge rate, 2. directly related to the drain spacing only for very small values of the spacing, 3. directly related to the thickness of the aquifer, 4. inversely-related to the permeability.
