Abstract In this research, the impact of human factors and climate change on groundwater level fluctuations affected by uncertainty within 27-year upcoming period (2018–2045) in Razan Plain is examined. To simulate aquifer performance, GMS model calibrated verified for two 18-month periods, respectively. forecast variables changes future time-frame, six CMIP5 models with three scenarios Rcp 2.6...

According to the characteristics of groundwater in arid area, this paper proposes DRAV model for groundwater vulnerability assessment, where D is groundwater depth, R is the net recharge of aquifer, A is the aquifer characteristics, and V is the lithology of vadose zone. As a case study, the paper assesses the vulnerability of pore phreatic water in Tarim Basin of Xinjiang, China by using the D...

Five periods of increased electrical conductivity have been found in the karst conduits supplying one of the largest first magnitude springs in Florida with water. Numerous well-developed conduit networks are distributed in the Woodville Karst Plain (WKP), Florida and connected to the Gulf of Mexico. A composite analysis of precipitation and electrical conductivity data provides strong evidence...

Groundwater resources along with surface-water meet the needs of urban, industrial, and agricultural sectors, therefore, their quality should be examined. Water indices are useful tools for aquifer management. In this research, groundwater Miandoab Plain in province West Azerbaijan, northwest Iran, purposes was investigated. For purpose, concentrations ions Mg2+, Ca2+, Na+, HCO3−, SO42−, Cl− pH...

The release of colloids to groundwater was investigated in situ in an ironoxyhydroxide-rich, sandy aquifer. Groundwater amended with various solutes was injected into and immediately withdrawn from the shallow aquifer. Turbidity and colloid composition were monitored in the retrieved injectate. The response of the aquifer material to the amendments generally mimicked that observed in an earlier...
