Abstract

"The computer program, MODFLOW, was used to simulate the performance of the U.S. Army Corps of Engineers - St. Louis District levee system from Alton to Gale, Illinois. The gravel pack hydraulic conductivity of these relief wells was found to decrease at an average rate of 0.375 feet per second/feet per second/year. This rate was based on the assumption that the initial hydraulic conductivity of the gravel pack was 1.6 x 10⁻⁴ feet per second. An equation was developed to convert specific capacity (data obtained during a pumping test) to specific flow (data obtained during a high-water event).

A procedure was developed to predict flow within the levee system during high-water events. Two types of analysis can be applied to the procedure. A present-day analysis predicts the efficiency of a relief well in its current, existing condition. A future-date analysis predicts the efficiency of a relief well at some future time. The results of either analysis could be used to predict pore pressures and uplift gradients within the levee system"--Abstract, page iv.
