Effect of Surface Water Level Fluctuations on the Performance of Near-Bank Managed Aquifer Recharge from Injection Wells

Managed aquifer recharge operations are often conducted in near-bank areas to regulate water resources or reduce seawater intrusion. Yet little is known about the influence of surface level fluctuations at different temporal scales on MAR performance. A generalized conceptual model was developed based an investigation site Western China as a basis simulate response table, artificially recharged lens (formed by water), groundwater flow paths and average travel times (which important control how quickly contaminants flushed out aquifers), discharge during fluctuation. The results showed fluctuating table under fluctuations. peak values increment induced artificial decreased with increase period amplitude fluctuation, but trough increases that. penetration depth into leads decreasing which follows power law. dynamic changes morphology thinner lens. mixing zone ambient could be found area, expected lead modifications geochemical conditions aquifer. longer fluctuation time, larger shorter time. decrease it amplitude.
