Episodic And Continuous Recharge Estimation From High-Resolution Well Records, Timothy Eaton

Publications and Research

Water table fluctuation (WTF) methods are a primary and well-established way to determine groundwater recharge based on the direct response of the water table to precipitation input. An emerging complexity of recharge is whether it occurs as an episodic and transient process, or a continuous steady-state process, however most studies have not focused on these short-term vs long-term timescales, in part because of a lack of data resolution. Here, high-resolution (subhourly) precipitation and water level data are analyzed for wells in the suburbs of New York City using two contrasting WTF approaches, with a common mathematical basis, that are suited …
