In order to study the ecological water environment in Erhai Lake, different monitoring sections were set to research the change of hydrodynamics and water quality. According to the measured data, MIKE21 Ecolab, the water quality simulation software developed by DHI, is applied to simulate the water quality in Erhai Lake. The hydrodynamics model coupled with water quality is established by MIKE2...

NJWRRI has funded research on topics ranging from pollutants in ground and surface waters to the behavior of estuarine fish to the ecology of wetlands. With funds provided by Congress and Rutgers University, the NJ Water Resources Research Institute supports a program of research each year which addresses a periodically-updated list of priority issues developed by the Advisory Council in consul...

Watersheds are recognized as the most effective management unit for the protection of water resources. For surface water supplies that use water from upstream watersheds, evaluating threats to water quality and implementing a watershed management plan are crucial for the maintenance of drinking water safe for humans. The aim of this article is to establish a risk assessment model that provides ...

This paper utilizes United States Geological Survey (USGS) data to investigate the influence of landscape structure on atmospheric circulations. The procedure to insert this data in the Regional Atmospheric Modeling System (RAMS) is described. Simulations are presented for a monthly simulation of summer weather in the United States, for case studies of cumulonimbus convection along a dryline in...

The main objectives of waters and aquatic environmental protection aim preventing the damage of all surface waters and progressive reduction of pollution, gradual cessation or elimination of evacuation and loss of pollutants in the surface waters, as preventing or eliminating the contribution of pollutants in underground waters and preventing the damage of their.Gratifying water requests, prote...

Municipal wastewater treatment plants consume much energy and manpower, are expensive to run, and generate sludge and treated wastewater whilst removing pollutants through specific treatment regimes. The sustainable development of the wastewater treatment industry is therefore challenging, and a comprehensive evaluation method is needed for assessing the sustainability of different wastewater t...

This inequality is especially critical for Asia, which has 60% of the world’s population but only 36% of the world’s water. Water quality in terms of pollutant loading also is not distributed equally and is related to the type of use and a country’s level of development (Figure 2). Developing countries often have less capacity to improve water quality and depend on lower-quality water for a var...

The Ogba River in southern Nigeria is an important water resource for its riparian communities. This study evaluates impact of anthropogenic influences on the Ogba River using water chemistry and macroinvertebrate data sets obtained over a period of 6 months between January and June 2012. Four stations, stations 1-4, characterised by various human activities were chosen along the river. Organic...

GOAL, SCOPE AND BACKGROUND Aquaculture activities are well known to be the major contributor to the increasing level of organic waste and toxic compound in the aquaculture industry. Along with the development of intensive aquaculture in China, concerns are evoked about the possible effects of ever-increasing aquaculture waste both on productivity inside the aquaculture system and on the ambient...

The Soil and Water Assessment Tool (SWAT) model has emerged as one of the most widely used water quality watershed- and river basin-scale models worldwide, applied extensively for a broad range of hydrologic and/or environmental problems. The international use of SWAT can be attributed to its flexibility in addressing water resource problems, extensive networking via dozens of training workshop...
