groundwater quality in nour coastal plain in mazandaran province of iran is assessed by measuring physicochemical parameters including total dissolved solid, electrical conductivity, ph, total hardness, major cation and anion compositions and nitrate pollution. for this purpose, fifty groundwater samples were collected in july 2012. the hydrochemical types, ca–hco3 and mg–hco3 dominate in all s...

Full coupling of physical processes, natural numerical coupling, and parsimonious but accurate data coupling are three key steps in efficient and accurate simulation of distributed hydrologic states in watersheds. Here we present a physically-based, spatially distributed hydrologic model (called PIHM) that utilizes all the three coupling strategies. Interception, snow melt, transpiration, evapo...

Contaminant hydrology is the study of processes that affect both ground and surface water pollution. It draws on the principles of hydrology and chemistry. Contaminant hydrology and water quality research seeks to understand the role of soil properties and hydrologic processes on ground and surface water pollution and develop strategies to mitigate their impacts. Research is done at all scales ...

Abstract Endorheic basin brines are of economic significance as sources boron, iodine, magnesium, potassium, sodium sulfate, carbonate, and tungsten, they a major source the critical metal lithium. Although evaporation is primary hypersalinization driver for evaporative water bodies, recent investigations have proposed more novel mechanisms some subsurface brine. This investigation explores sha...

Chlorides commonly precipitate during the evaporation of surface water or groundwater and during volcanic outgassing. Spectrally distinct surface deposits consistent with chloride-bearing materials have been identified and mapped using data from the 2001 Mars Odyssey Thermal Emission Imaging System. These deposits are found throughout regions of low albedo in the southern highlands of Mars. Geo...

The Tabu catchment, a typical-desertified steppe in China, was selected as the study area to qualitatively analyze interaction between surface water (SW) and groundwater (GW), an integration of hydrochemical analysis isotopic techniques applied. results show that ion contents SW GW increased from upstream downstream, evolutions were both controlled by rock weathering influenced evaporation. δD–...

The article presents the research results devoted to water-saving irrigation technology on steep slopes and clarifies elements of techniques at contour discrete in south Uzbekistan. muddy water for drip gardens has been developed. implementation intensive resulted a 20-60% reduction consumption arable land, up 50% mineral fertilizers 30% fuel lubricants. Also, groundwater level does not rise du...
