Mobilization of environmentally hazardous elements from loparite ore tailings when exposed to various leaching agents was studied in laboratory conditions. Leaching pollutants fresh atmospheric precipitation and the processes interaction mature dust particles (-0.071 mm) with soil water were examined. It found that both cases, there is an intensive decomposition minerals making up conversion he...

The main purpose of the study is determination of the pollutants hazard potential as well as environmental vulnerability of Qarah Su River. First the most significant pollutant sources in the Qarah Su river watershed were identified and then accordingly the pollution hazard potential rate was calculated in Universal Ranking System Model setting. Then, by generalizing the algebraic sum of the re...

Flash flood has been increasing in the Khartoum area, Sudan due to geographical conditions and climatic change as heavy rainfall and high temperature, therefore the present work tried to estimate the sensitivity of flash flood. The present work proposes an advanced technique of flood sensitivity mapping using the method of analytical hierarchy process. Ten factors as elevation, slope, distance ...
