Abstract: Introduction: Foundation conditions in the vicinity of the outlet structures at Grenada Dam consist of pervious sand strata beneath impervious strata which underlie the bottom of the excavation for the above structures. Piezometers previously installed along the outlet works indicated that hydrostatic pressures in the sand strata approximately equal the stage in the Yalobusha River. Studies made by the Waterways Experiment Station disclosed that it would be necessary to reduce the hydrostatic pressures in the sand strata underlying the bottom of the excavation to safe values for all possible river stages during excavation and construction. A pressure relief system was designed for this purpose. The results of the above investigations including the design of the pressure-relief system are contained in the report "Design of Closure Section and Pressure-Relief System for Outlet Structure Excavation, Grenada Dam," Waterways Experiment Station, March 1951.
