it is well known that, contaminant transportation is a major problem in coastal zones and has to be faced when coastal structures are being planned. sea pollution not only causes environmental damage, but also impacts quality and population of sea resources. oil is the most important pollutant, pollutants emanating from industries, ships, drilling and exploration in the seabed, ship sewage, tox...

air pollution is one of the major threats to environment in the present time. increase in degree of urbanization is a major cause of this air pollution. due to urbanization, vehicular activities are continuously increasing at a tremendous rate. mobile or vehicular pollution is predominantly degrading the air quality worldwide. thus, air quality management is necessary for dealing with this seve...

background: the air dispersion models are widely used to evaluate and predict the pollutants emissions from air pollution sources such as incinerators. this study attempts to predict the heavy metal pollutants dispersion emitted by an incineration plant impacting its surrounding area. methods: several scenarios of emission rates coupled with the meteorological conditions were investigated using...

The integration of high dimensional geo-visualization, geo-data management, geo-process modeling and computation, geospatial analysis, and geo-collaboration is a trend in GIScience. The technical platform that matches the trend forms a new framework unlike that of GIS and is conceptualized in this paper as a collaborative virtual geographic environment (CVGE). This paper focuses on two key issu...

The current study assesses critical condition of oil dispassion, considering the unsaturated soil condition dispersity behavior for oil dispersion. The numerical model is used as a finite element method to model the oil spill pollution with two different saturated and unsaturated soil conditions chosen and their pollution dispersion results compared. Extracted results from numerical model show ...

The prime aim of this research is to support decision making, e.g., air quality impact analysis, human health assessment, through spatially modelling traffic-induced air pollution dispersion in urban areas at street level. Based on the information needed in decision making, a framework for a street level air quality decision support system is established, which is composed of basically three pa...

Dispersion of air pollution depends upon various factors including weather conditions, topography and local situation, causing large variation, even in small areas. In addition to mathematical dispersion models and interpolation methods, remote sensing can improve mapping of the spatial distribution of urban air pollution, although no dedicated sensors exist. We used aerosol optical thickness, ...

the agricultural non-point source pollution shows some special features such as dispersion, randomness, fuzziness and cumulative compared with industry and other point source pollution. Owing to lacking complete and systematic data on agricultural sources of pollution in the long-term, Agricultural non-point source pollution load of the new method "IS (Investigation-Statistics) estimation metho...
