Onshore Entrapment of Seawater in Coastal Aquifers by Rapid Coastline Progradation Open
We hypothesize that brackish groundwater within unconfined aquifers located in active river deltas may have resulted from rapid shoreline progradation during the Holocene. To explore this hypothesis, we develop a coupled model of variable‐…

Hydrologic windows into the crystalline basement and their controls on groundwater flow patterns across the Paradox Basin, western USA Open
Conceptual models of sedimentary basin groundwater flow systems typically assume that the crystalline basement acts as an impermeable boundary and can be neglected. In this study, we use hydrologic models constrained by isotopic and geoche…
