In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. Traditionally called “mountain-front recharge” (MFR), this process has been treated by modelers of basins as a boundary condition. In general, mountain-front recharge estimates are based on the general precipitation characteristics of the mountain (as estimated, e.g., by the chloride mas...

Groundwater accessed by handpumps is the primary water supply for many people in Africa. This “Smart Water” project considers the study of a region of Kenya where there is significant demand for groundwater, especially among the poor. Some of the engineering aims of this project are to determine if data acquired from accelerometers mounted in hand-pumps can be used to perform three tasks: (i) e...

The fate of nitrogen entering Long Island Sound Embayments is dependent on both volume of submarine groundwater discharge (SGD) and geochemical transformations in the coastal aquifer. Previous work in Stony Brook Harbor revealed the importance of sediment composition in the subtidal and offshore areas of the harbor; SGD rate in the subtidal is higher than offshore areas, but experiences only 30...

Korea has been operating groundwater monitoring systems since 1996 as the Groundwater Act enacted in 1994 enforces nationwide monitoring. Currently, there are six main groundwater monitoring networks operated by different government ministries with different purposes: National Groundwater Monitoring Network (NGMN), Groundwater Quality Monitoring Network (GQMN), Seawater Intrusion Monitoring Net...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Interactions between groundwater and surface water play a critical role in the functioning of riparian ecosystems. In the context of sustainable river basin management it is crucial to understand and quantify exchange processes between gro...

FOREWORD The potential use of plants to remediate contaminated soil and groundwater has recently received a great deal of interest. EPA's Technology Innovation Office (TIO) provided a grant through the National Network for Environmental Management Studies (NNEMS) to assess the status of phytoremediation technologies to clean up shallow groundwater. This report was prepared by a graduate student...

In groundwater remediation, Groundwater Circulation Wells (GCW) are used as an alternative to typical Pump & Treat (P&T) methods. Extraction and injection are operated in a single well with multiple isolated screened intervals, which creates a three-dimensional flow pattern (circulation cell) in the aquifer. The utility of GCW pump test data can be increased using groundwater modelling to asses...
