Climate change is expected to increase stream temperatures and the projected warming may alter the spatial extent of habitat for cold-water fish and other aquatic taxa. Recent studies have proposed that stream thermal sensitivities, derived from short-term air temperature variations, can be employed to infer future stream warming due to longterm climate change. However, this approach does not c...

Ground water is the major source of freshwater on the earth. Groundwater containing dissolved ions beyond the permissible limit is harmful and not suitable for domestic use. Fluoride beyond desirable amounts (0.6 to 1.5mg/l) in groundwater is a major problem in many parts of the world. The fluorides belong to the halogen group of minerals and are natural constituents of the environment. Fluorid...

The water quality of the Nant Tanllwyth stream in the Plynlimon region of mid-Wales is related to the key hydrobiogeological controls and the effects of conifer harvesting based on an analysis of rain, cloud, stream and groundwater measurements. The results show the normal patterns of stream water quality response to hydrology. Thus, there is a high damping of atmospheric inputs due to storage ...

Forests are critical water supply regions that increasingly threatened by natural and anthropogenic disturbance. Evaluation of runoff-generating processes within harvested undisturbed headwater catchments provides insight into disturbance impacts on quality drinking treatability. In this study, an extensive hydrologic dataset collected at the experimental Turkey Lakes Watershed (TLW) located Ca...

this research was conducted in order to study the effect of climate and geology factors on groundwater sources in mahvelat plain. in order to study the groundwater quality and quantity considering groundwater resources including wells and qanats; using groundwater surface, electric conduction (ec) and the total density solution (tds), the maps of groundwater surface fluctuation and quality para...
