Upstream soil and water conservation measures in catchments can have positive impact both upstream in terms of less erosion and higher crop yields, but also downstream by less sediment flow into reservoirs and increased groundwater recharge. Green Water Credits (GWC) schemes are being developed to encourage upstream farmers to invest in soil and water conservation practices which will positivel...

Soil and groundwater salinization are major problems for irrigated agriculture in many arid and semiarid areas of the world. Studies addressing such problems require accurate estimation of salt loadings from irrigated areas through the vadose zone to underlying groundwater. We studied Cl transport in the vadose zone at 45 locations in a field in the San Joaquin Valley, California, through a com...

[1] Magnitudes of terrestrial (fresh) and marine (saline) sources of submarine groundwater discharge (SGD) are estimated for a transect across Indian River Lagoon, Florida. Two independent techniques (seepage meters and pore water Cl concentrations) show terrestrial SGD decreases linearly to around 22 m offshore, and these techniques, together with a model based on the width of the outflow face...

Abstract Uchalli Lake (Ramsar site), with a surface area of 14.3 km2, is the largest lake Uchhali Wetlands Complex. Heavy inorganic pollution (metals and nutrients) load in had been reported by other researchers, but sources its effects on surrounding groundwater have never investigated. In present study, stable isotopes δ18O δ2H were applied to find out recharge groundwater. Additionally, δ15N...

This study conducts a detailed analysis of multiscale periodic features involved in the annual and seasonal precipitation signals at the typical coastal reclamation region in China by selecting the suitable continuous wavelet transform (CWT) and innovatively combining the improved Hilbert–Huang transform (HHT), and further deduces the precipitation trend and its impacts on the future soil hydro...

The solar steam process, akin to the natural water cycle, is considered to be an attractive approach to address water scarcity issues globally. However, water extraction from groundwater, for example, has not been demonstrated using these existing technologies. Additionally, there are major unaddressed challenges in extracting potable water from seawater including salt accumulation and long-ter...

The spatially distributed hydrologic model WetSpa is applied to the Torysa river basin (1,297 km) located in Slovakia. Daily hydrometeorological data from 1991 to 2000 are used as input to the model. The spatial characteristic of the basin are described by three base maps, i.e. DEM, landuse and soil type, in GIS form using 100 m cell size. Results of the simulations show a good agreement betwee...

Introduction: Relief inversion explains a wide range of sinuous and dendritic ridges on the martian surface as well as elevated craters [1]. The process occurs when former depressions become elevated because their fill is more resistant to erosion than the surrounding terrain. On Mars the most likely cementing agents for surface induration are iron oxides, opalline silica, sulfates and perhaps ...

groundwater can be used directly or indirectly and any decline in its quality or quantity maynegatively impact the environment. through groundwater valuation, people are made aware of the fact thatgroundwater is not free of charge and therefore the significance of groundwater preservation is established. in this study, groundwater quality preservation value has been estimated for the city of ya...
