Factors Affecting Areas Contributing Recharge to Wells in Shallow Aquifers

摘要

Hypothetical experiments were undertaken to show the complexities in thedelineation of areas contributing recharge to wells. Four different cases are examined to demonstrate the effect of different conceptualized aquifer frameworks on deterministically calculated areas contributing recharge. The main conclusion drawn from the experiments is that, in order to understand the cause and effect relations that affect the quality of water derived from wells, the importance and nature of the variability in the ground-water-flow system must be considered and accounted for in any efforts to protect the water supply.
