Base Flow Recession Analysis for Streamflow and Spring Flow
… groundwater head, spring pool altitude, and net recharge into the existing Torricelli model. The results show that the effective springshed area has continuously declined since 1988. The net recharge has declined since the 1970s with a significant drop in 2002. Subsequent to 2002, the net …

Hydrogeology and Simulated Water Budget of the Rio Cobre and Rio Minho-Milk River Basins, Jamaica, West Indies
… of the White Limestone aquifer are reasonable. Recharge to the area occurs as net recharge in addition to upland subsurface inflow across the general head boundary in the northern part of the study area. Comparisons of calculated and observed values of head indicate that simulated groundwater …

Groundwater vulnerability assessment for nitrate pollution in the Salinas Valley using a modified DRASTIC model
… vulnerability that incorporates depth to water, net recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity. In order to modify the DRASTIC model to assess nitrate contamination specifically, a land use parameter was incorporated into the model. The …

Surface-water groundwater interaction and arsenic mobilization in south and southeast Asia
… In particular, the influence of surface water recharge on arsenic contamination remains unresolved. To address this issue we studied the hydrogeology and geochemistry of two arsenic contaminated sites: one site in Vietnam and another site in Bangladesh. Our field site in Vietnam is located …

The use of remote sensing and GIS for water resources management in large semi-arid regions: A case study of the Lake Chad Basin, Africa.
… significant differences in the estimations of recharge and discharge phenomena of the Quaternary aquifer. Another scientific issue is the presence across the Quaternary aquifer of large piezometric depressions (Eberschweiler, 1992; FAO-Schroeter and Gear, 1973; Greigert, 1979; Schneider, 1969; …
