dc.description.abstractThe zone between the ground surface and the top of the groundwater is called the unsaturated zone. The flow in the unsaturated zone interests researchers who wish to understand the movement of both fluid and contaminants from the ground surface to the water table. Problems such as assessing the groundwater pollution hazards of sanitary landfills or feedlots, estimating the results of air injection for secondary recovery of capillary water, and planning artificial recharge by surface spreading require accurate knowledge of the flow in the unsaturated zone. This research dealing with mathematical modeling of pressure changes in the unsaturated zone can provide necessary information for solving these problems.
