ity in the Glassboro, NJ area (Fig. 1). The Darcian method was used to estimate groundwater recharge Point estimates of groundwater recharge at 48 sediment-coring from water-retention parameters and unsaturated hylocations vary substantially ( 18.5–1840 cm yr 1) in a 930-km2 area of southern New Jersey. Darcian estimates of steady, long-term recharge draulic conductivity on the basis of sedimen...

Floods are of great concern as the global climate changes, and investigations of flood water infiltration and groundwater recharge are important for water resource management worldwide, especially under conditions of global climate changes. However, information on the relationship between the flood water and groundwater recharge is limited. The objective of this study was to determine the relat...

In the project RIVERTWIN climate, hydrologic, groundwater and water quality models are integrated in order to evaluate river basin management plans established for the implementation of the EU Water Framework Directive. In such integrated models, which try to simulate all relevant processes in a river basin realistically, modelling of the water balance plays a key role. Therefore the integratio...

Flooding’s impact on shallow groundwater is not well investigated. In this study, we analyzed changes in the depth and quality of a regional shallow aquifer in the 10.9 × 104 km2 Sanjiang Plain, Northeast China, following a large flood in the summer of 2013. Pre(2008–2012) and post-flood records on groundwater table depth and groundwater chemistry were gathered from 20 wells across the region. ...

The great majority of Southern African aquifers depend on rainfall for their recharge. The accurate estimation of recharge remains one of the biggest challenges for groundwater investigators. Accurate recharge estimations are needed for proper groundwater management as this governs the estimation of sustainable exploitation. Current estimates of recharge to aquifers range between 0.2 and 3% of ...

Mean groundwater levels of a multi-layered coastal leaky aquifer system are considered. The system consists of an unconfined aquifer, a confined aquifer and a semi-permeable layer between them. Both exact asymptotic solutions and approximate perturbation solutions are derived for multi-sinusoidal-component sea tide. At inland places far from the coastline, the perturbation solutions show a good...

Problem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the Makeng area have been deve...

This study investigates the feasibility of management of aquifer recharge (MAR) in Lebanon by designing well barriers to remove seawater intrusion from the fractured carbonate aquifers. Groundwater flow and saltwater/freshwater 50% sharp interface have been modeled along the coastal area using the Ghyben-Herzberg theory. The groundwater flow simulations have been supported by field transmissivi...

An assessment is made on the current groundwater use and further development potential in the hard to reach (HtR) areas of Bangladesh following a combination of secondary literature review and synthesis of primary information gathered from the fields. Also, primary analyses of groundwater quality, levels, recharge and use were done using secondary data. The findings reveal that the hydrogeology...
