[1] The hydrology and geochemistry of groundwater in tropical island aquifers, such as on Barbados, are significantly influenced by tropical climatic conditions. Recharge to these aquifers is the product of regional and local climate patterns that control rainfall. Oxygen isotopes can be used to estimate the amount and timing of recharge on these islands because seasonal fluctuations of rainwat...

This study applies a production function approach to value the groundwater recharge function of the Hadejia-Nguru wetlands in northern Nigeria. The groundwater recharge function supports dry season agricultural production which is dependent on groundwater abstraction for irrigation. Using survey data this paper first carries out an economic valuation of agricultural production, per hectare of i...

Artificial groundwater recharge is a process by which the groundwater reservoir is augmented at a rate exceeding the augmentation rate under natural conditions of replenishment. In some parts of India, due to over-exploitation of groundwater, decline in groundwater levels resulting in shortage of supply of water, and intrusion of saline water in coastal areas have been observed. In such areas, ...

Groundwater recharge is essential to groundwater resources availability to economy and society development in semiarid areas. Chloride mass balance method to assess groundwater recharge have been review and was employed to quantify groundwater recharge in North Okanagan which is a semiarid mountainous terrain, southern interior British Columbian, Canada. Chloride concentration in precipitation ...

Over-exploitation of coastal aquifers causes seawater intrusion and eventually contamination of groundwater wells in many parts of the world. Artificial recharge of treated wastewater can be used to avoid or control seawater intrusion. A common characteristic of many coastal areas in Southern Europe is that most of the annual water demand, and hence the amount of water that can be used for arti...

This study tests the representativeness of groundwater recharge estimates through the chloride mass balance (CMB) method in a tropical environment. The representativeness of recharge estimates using this methodology is tested using evaporation estimates from isotope data, the general spatial distribution of the potential field, and the topographical variations in the area. This study suggests t...

Sustainable groundwater production from karst aquifers is primarily dictated by its recharge rate. Therefore, it is essential to accurately quantify annual groundwater recharge in order to limit overexploitation and to evaluate artificial methods for groundwater enrichment. Infiltration during erratic flood events in karst basins may substantially contribute to aquifer recharge. However, the co...

The present research work was undertaken to estimate the ground water recharge in Shankergarh block, Allahabad (India) during the year 2008. The data set used consisted of satellite derived rainfall and actual evapotranspiration and SCS-CN model estimated runoff values. The monthly values of the different components of water balance equation were estimated and subsequently the ground water rech...

Artificial recharge can be an effective method to raise the groundwater table and to resolve the groundwater crisis in Sefid dasht plain. The most important step to successful accomplishment of artificial recharge is locating suitable areas for artificial recharge. Hence this research carried out with purpose of determining suitable areas for artificial recharge in Sefid dasht plain. Slope, sur...

Water is the main option of any development, so having an accurate management of groundwater is necessary. This study has been done in Damghan sedimentary plain in Iran, which is located in northwest of Semnan Province. The main objective of this research was to estimate the rate and right site of recharge in Damghan plain to prevent the aquifer from decreasing the water table. For this purpose...
