Nacharam and its surroundings, located inside the city of Hyderabad in Telangana State, India, is vulnerable to water-borne diseases; therefore, the present research works on concentrations of dissolved hexavalent chromium (57-263 mgL-1), lead (34-65 mgL-1), cadmium (2.3-22.4 mgL-1), and nickel (from below detection limit to 6.5 mgL-1) in different surface water and groundwater bodies of this a...

Responses of wetland carbon cycling to environmental changes, particularly changes in water table depth, which are the key determinants to control the ecological and biogeochemical functions of wetlands, are highly non-linear and complex due to the dynamic interactions of several physical and biological processes. Several field experiments have found that wetland productivities have a significa...
a field study was conducted to evaluate the possibility of using water table control techniques in the semi arid region of iran with special attention to its salinity management. the wtm consisted of three subirrigation treatments with water table controls set at 0.3, 0.5 and 0.7 m from the soil surface and a free drainage (fd) treatment. the electrical conductivity (ec) of water was 1.5 ds/m. ...
groundwater drought denotes the condition and hazard during a prolonged meteorological drought when groundwater resources decline and become unavailable or inaccessible for human use. the aim of this study is to identify the influencial factors on groundwater drought in hamadan- bahar watershed,iran, to understand the forcing mechanisms. the standardised precipitation index (spi) has been used ...
