Design of Dewatering Systems - 3 PDH

Course Description

This course discusses design of a watering and pressure relief or groundwater control system.  To do this first requires determination of the type of groundwater flow (artesian, gravity, or combined) to be expected and of the type of system that will be required. Also, a complete picture of the groundwater and the subsurface condition is necessary. Then the number, size, spacing, and penetration of wellpoints or wells and the rate at which the water must be removed to achieve the required groundwater lowering or pressure relief must be determined.
