An integrated curriculum, which draws material from different areas to teach students about design and problem-solving, offers civil engineering educators an option for accommodating new topics without increasing the number of courses. Freshman engin

Exact integral solutions for the horizontal, unsteady flow of two viscous, incompressible fluids are derived. Both one-dimensional and radial displacements are calculated with full consideration of capillary drive and for arbitrary capillary-hydrauli

One of the most common methods of artificial recharge to the ground water is from basins. In this paper, seven analytical solutions that describe artificial recharge from basins are presented. Most of these solutions are derived by directly solving t

The effect of capillarity on the transient response of the water table to recharge was evaluated by a numerical and a porous media model. The numerical model was developed to simulate the growth and spread of ground-water mounds taking into considera

A numerical model was developed to simulate the behavior of two-phase immiscible fluids in ground-water systems for specific application to hydrocarbon spills and leaks. The model is a two-dimensional areal flow model using the finite-element method.

Analytical solutions, accounting for the reduction in storage capacity caused by in-transit water, are presented for the growth of groundwater mounds in an unconfined aquifer in response to uniform deep percolation from a rectangular and circular rec

The three-phase fluid distribution caused by a petroleum spill in an unconfined aquifer was investigated experimentally. The experiment consisted of introducing oil at the top of a vertical column of soil containing water and measuring the soil and w

The study of ground-water contamination in the Severence Basin showed that the primary source of this contamination was the high evapotranspiration rate combined with the low degree of ground-water and surface water outflow from the basin. This condi

An analytical solution accounting for the reduction in storage capacity caused by in-transit water is presented for the growth of groundwater mounds in an unconfined aquifer in response to uniform deep percolation from a strip of infinite length but
