A study investigated physicochemical parameters in environmental matrices along the river Cerica waters. A corre- lation between the actual level of pollution of this river and its impact on the Drini i Bardhë River was determined. The extent of its pollution, was conducted following the identification of pollution sources, which consequently allowing to determine the necessary steps for their isolation...
Poor water quality in Pettipalam Colony in Thalassery, Kannur District, Kerala is the source of many health issues among the colony residents. Soil and water contamination due to the accumulation of waste is another serious issue that adversely affects the health of the inhabitants in the area. There is a compelling need for the village inhabitants to appropriately monitor the water bodies and take...
This paper investigated the spatial-temporal variations and pollution source of surface water quality by analyzing the data from 8 water quality monitoring stations along the middle and lower reaches of the Min River between 2003 and 2008. The results showed that surface water quality was worse in the middle reaches of the Min River than that in the lower reaches and its tributary. Seasonal and spatial...
Groundwater was monitored to investigate its hydrochemical variation and possible influencing factors from April, 2007 to May, 2009 at the inlet (D1) and outlet (S2) of Qingmuguan subterranean river in Chongqing, China. The response of the subterranean river discharge to rainfall events was very fast and dramatic, as the water level rising suddenly and dropping sharply with rainfall amount in the...
The remote sensing technology could identify the surface features by getting their reflectance spectral characteristics. Because of the different surface properties, nature and content of suspended solids, the characteristics of water bottom and depth of different water bodies, the reflectance spectral characteristics which were received from the transducer showed differences between each other. The...
Eutrophication is a worldwide pollution problem, when the point source pollution is efficiently controlled, pollution load from non-point source has the increasing proportion in the total load. Xiangxi River is selected as the research demonstration area to conduct preliminary study on non-point source pollution for frequent water bloom. Non-point source pollution factors are analyzed in Xiangxi River...
After water storage of Laohutan reservoir, nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH3-N) are the main pollutants. In the first month of water collection, the vertical distribution of TN, TP and NH3-N concentrations is increased distinctly from the surface layer to the bottom layer. It shows that the reservoir water quality is affected by pollutants released from submersed soil...
In Beijing, Wetlands have been playing a crucial role in conserving municipal freshwater and retaining biodiversity. The classification system of Beijing wetland has been set up. The interpretation keys of six main wetland types in Beijing, including River, Reservoir, City Lake, Artificial Canal, Pound and Paddy Field, were built up using TM/ETM+ multi-spectral pseudo-color composition images as the...
