We aim to find the time-dependent source term in the diffusion equation from the boundary measurement, which allows for the possibility of tracing back the source of pollutants in the environment. Bas...
In recent years, with the increasing world environmental pollution happening, sudden water pollution incident has become more and more frequently in China. It has posed a serious threat to water safet...
Researchers have uncovered previously hidden sources of ocean pollution along more than 20 percent of America’s coastlines.The study, published onlinAug. 4 in the journal Science, offers the fi...
In this paper, the one-dimension river quality system dynamics model was applied to the water quality simulation, and the conceptual GIS-SD frame was constructed. Based on the component GIS and system...
Water pollution caused by oil spills is a typical hazard scenario in which the understanding of object movement—here that of the oil spill—may be vital for risk minimization. Oil spills do not only p...
In order to evaluate the groundwater pollution, the application of statistical principal components analysis (PCA) was used as one useful tool. PCA was based on the physical– chemical data of groun...
This paper describes recent levels of surfactants measured in a coastal lagoon ecosystem highly stressed by human activites: the Orbetello lagoon (Southern Tuscany, Italy, Ramsar Site IT008). Signific...
Contamination of water reserves by biological, chemical, and radiologic agents may affect the health of millions of residents in the Iraq as well as many others throughout the world. Fatal outbreaks o...
Although modern European water policy follows a river basin approach where Member States have to cooperate in order to achieve a ‘good status’ of their water bodies, the obligations arising from the E...
Determination of the Effects of Water Pollution of Aquacultures using Neural Networks。
We analyzed the degree of pollution of the water in irrigation ponds in part of Kagawa prefecture and simulated the amount of nitrogen in water to evaluate the beneficial effect of dredging and excava...
An investigation of agricultural chemicals and chemical fertilizer used by golf links were carried out from June 1991 to May 1992. Immediately after or during the rainfall, sampling for drainage was s...
In 1972 Congress established the Federal Water Pollution Control Act in which the Environmental Protection Agency was given responsibility to “restore and maintain the chemical, physical, and biolo...
For the simulation of water movement and pollutant transport in the hydromorphic soil profile two numerical models SWATREZ and UNDYS were used. These models are based on water movement in porous mater...
