Analytical modeling of groundwater contamination under uncertainty

Groundwater contamination is considered to be one of the most significant ecological and health problems. The contaminant released from the source will move down-gradient of the groundwater flow and greatly affects the general environmental features of large regions and drinking water supply conditi...

description Groundwater contamination is considered to be one of the most significant ecological and health problems.
