Urban growth and land use change models are an important and innovative tool that support planning and development of sustainable urban areas. The data requirements for parameterization, calibration and validation of urban models are intense due to the complexity of the models and their objectives. In this study several urban land use change models are evaluated and their demands on spatial dat...
Application of gepraphic information system and image processing in evaluation of surface runoff of a watershed in recent years has increased greatly. In the study , the runoff curve number map was prepared using geographic information system (GIS)and Landsat Sattelite Images (ETM+)for two watersheds of Mansourabad in southern Khorasan province and Navroud in Gilan province based on the facto...
The topical problem of oil pollution monitoring in water areas is considered in the paper. Recently, the solution to this problem has been found by the complex use of space and land data within geoinformation systems. Thus, the data obtained from remote sensing of Earth (RSE) satellites supplement the data obtained from traditional land-based and aviation sources. Features of application of bot...
While considerable attention has been paid to the land application of sewage sludges and composted sewage sludges in the U.S. during the last twenty years, land application of municipal solid waste (MSW) composts has received comparatively little attention.

Poultry litter contains many trace elements such as As, Cu, and Zn, and its land application may lead to the accumulation of these elements in soils, especially near the soil surface. The objectives of this study were to determine the total amount of trace elements and evaluate the effect of litter granulation and various litter to water extraction ratios on water extractable trace elements in ...
The majority of U.S. sewage sludges are disposed by application to land for use as a soil amendment. Class B sludges, containing a complex mix of chemical and biological contaminants, comprise the majority. Residents near land application sites report illness. Symptoms of more than 328 people involved in 39 incidents in 15 states are described. Investigation and tracking of the incidents by age...
