The water crisis is harmful effects on human life. Also one of the most problems in the human society is water resources management. In this study, site selection of most suitable areas for artificial recharge using Boolean model. Criteria used to select the most suitable area for artificial recharge included: infiltration, slope, aquifer thickness, aquifer quality.  The layers were produced an...

this paper has focused on the application of hydro- geochemical techniques in conceptualizing of groundwater and to estimate recharge/discharge and the renewability of aquifer in hashtgerd watershed, iran. at first, the aquifer boundary was defined based on data of existing wells and basin morphologic conditions. estimation of recharge rate at different depth intervals by using tracer mass bala...

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...

A Monte Carlo-based approach to assess uncertainty in recharge areas shows that incorporation of atmospheric tracer observations (in this case, tritium concentration) and prior information on model parameters leads to more precise predictions of recharge areas. Variance-covariance matrices, from model calibration and calculation of sensitivities, were used to generate parameter sets that accoun...

Water and nutrient availability for crop production are critical issues in (semi)arid regions. Unsaturated-zone Cl tracer data and nutrient (NO3 and PO4) concentrations were used to quantify recharge rates using the Cl mass balance approach and nutrient availability in the Thar Desert, Rajasthan, India. Soil cores were collected in dune/interdune settings in the arid Thar Desert (near Jaisalmer...

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...

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...

The Kumamoto area, Kyushu, Japan has 1,041km in area and about 1milion in population. This area is a greatest area in Japan which depends on groundwater for all of drinking water. Quantity of this local groundwater use is about 200MCM during the year. It is understood that the main recharging area of groundwater exist in the rice field zone which have high infiltrate height ahead of 100mm/ day ...
