Analysis of Piezometer and Relief-Well Data. Report Number 1: Data from Sardis Dam, Mississippi
Abstract
Data obtained from tests and observations of the extensive piezometer and relief-well systems at Sardis Dam, Mississippi, are analyzed in this report in furtherance of a Corps of Engineers program to study the performance of earth dams and foundations. The data derived from these studies are to be used to assist in solution of problems encountered in the design of future, similar structures. Subsurface conditions existing at Sardis Dam were conducive to dangerous hydrostatic heads in the vicinity of the downstream toe. Evidence of these conditions was noted by the emergence of seepage on the downstream slope and berm at comparatively low reservoir elevations. A relief-well system was installed as a remedial measure to insure the stability of the structure. This report includes analyses of conditions before and after the installation of the relief-well system. The study shows that the design of the system is satisfactory and that the possibility of dangerous hydrostatic pressure conditions at maximum reservoir elevations has been eliminated.
