This study investigates the potential impact that aquaculture can have on solute transport and saltwater intrusion in coastal settings. It is certainly an interesting read, and an interesting conceptual problem. Typically when we think of vertical saltwater intrusion it’s due to coastal inundation associated with temporary natural causes like storm surges. However, with shrimp pond aquaculture saline ponds are actually perched on top of agricultural soils, above a freshwater aquifer. In this study the authors have investigated several scenarios (varying pond water salinity, ponded water depth and farm/pond width) to see how it impacts a previously unrecognized/unstudied process contributing to groundwater salinization.
