Abstract

"Every year the United States Anny Corps of Engineers (COE) is faced with the need to rehabilitate aging levee relief wells located along the major rivers and their tributaries in this country. Many of these wells where installed in the late 1950's and 1960's and are in need of some degree of rehabilitation. This is a costly and time-consuming process in which the COE has to decide which wells are in the most need of rehabilitation. This is, at best, an art with no real scientific method or procedures used to decide which wells to rehabilitate, and in what order.

A methodology is needed to determine the most economic and critical time to rehabilitate any given relief well such that the integrity of the levee and the safety of persons and property behind these levees are not compromised In doing so, the resources of the COE are utilized in a more effective, economic, and beneficial manner. Wells that are still providing the needed service are left alone until the time comes when they no longer provide the level of safety required.

The methodology developed in this study encompasses the use of computer software to model the subsurface flow behavior at a levee section. These computer programs include an underseepage software package (Visual MOD FLOW or SEEP/W) combined with a slope stability package (UTEXAS3, SLOPE/W, or PCSTABL). Using this software combination, a methodology was developed in which the COB can more effectively determine rehabilitation needs of relief wells"--Abstract, page iii.
