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...
Agricultural water resource, main body of regional water resources, was affected by multiple factors (e.g. landform, climate, precipitation and water system). Based on the investigation of water resources in the upper reaches of Minjiang, in order to scientifically manage and utilize agricultural water resource in this region, some feasible measures of sustainable exploitation were as follow: 1) expedite...
Growing switch-grass in a riparian buffer zone can be one of future best management practices in water resource protection. Switch-grass requires no fertilizers and less land and water. It was recently found to be a good source of biomass. In this study, Soil and Water Assessment Tool (SWAT) model was applied to a watershed to examine the effectiveness of buffer zones of switch-grass in reducing pollutants...
The main purpose of the research is to study the influence on shallow ground water by heavy metal in polluted river. In the lab-scale experiment polluted rivers were simulated by domestic sewage, and three kinds of natural sand were chosen as infiltration medium, it was found that Cr(VI) penetrated on the 13th day and then had a removal ratio of 77-99% in coarse sand, over 91% and 96% in two kinds...
Hydrological and water quality simulation faces big challenge because of intensive human activities in the Zhangweinan Canal sub-watershed of the Hai River basin. The Soil & Water Assessment Tools (SWAT) modeling system was established depended on various of spatial and attribute data of this watershed, and parameters for hydrological, water quality and evapotranspiration (ET) simulation were...
The development and significance of the best management practice for controlling urban runoff quality are reviewed briefly. Several regular BMP types, together with their functions, removal efficiency of target pollutants, runoff volume control, design considerations, community acceptance and construction characteristics, etc. are described. The fuzzy hierarchy recognition model and computation procedures...
The present conditions, causes of sandification and its impacts on the ecological functions of Xianghai wetlands have been studied. Results indicate that human irrational exploitation is the key cause of the sandification of the wetland. The ecological functions of the wetlands, for instance, in flood control, pollution filter, water purification, aquatic productivity, and habitat provision for a...
Clean drinking water plays a very important role in the health of a community. Providing safe drinking water to the people has been a major challenge for Romanian Government in order to achieve the goal of accession into the EU by 2007. The main purpose of this research was to investigate the chemical contamination of groundwater in a rural region from Cluj County, Romania. Samples of water from twenty...
