TP – 1104 An Introduction to Design of Groundwater Relief Wells for Professional Engineers

Description

Pressure relief wells as used in this manual refer to vertically installed wells consisting of a well screen surrounded by a filter material designed to prevent inwash of foundation materials into the well.Pressure relief wells have also been used extensively beneath the stilling basins of spillways, outlet structures, and other hydraulic structures. In addition, wells have been employed to control excess hydrostatic pressures in outlet channels including areas immediately downstream of navigation locks. Often wells incorporated in structures have been located so that they discharge through collector pipes and manholes which are not readily accessible to cleaning and maintenance unless the structures are dewatered.
