Intended Audience and Benefit
This course is intended for structural engineers, geotechnical engineers, environmental engineers, hydrologic\hydraulic engineers, geo-hydrologists, municipal engineers, project managers, and any persons working in civil engineering field or anyone with an interest in Design, Construction, and Maintenance of Relief Wells.
Course Introduction
Maintenance relief wells are constructed to relieve the subsurface hydrostatic pressures which may develop within the pervious foundations of dams, levees, and hydraulic structures. Relief wells function as artificial springs to reduce pressures to safe values.
Relief wells consist of a well screen, a riser pipe that is surrounded by a filter material designed to prevent the infiltration of soil fines into the well.
