Groundwater control: design and practice (second edition)

When an excavation is made below the water table there is a risk that it will become unstable or flood unless measures are taken to control the groundwater in the surrounding soil. This publication provides information and guidance on dewatering methods used to control groundwater as part of the temporary works for construction projects. Subjects covered include potential effect of groundwater on construction works, groundwater control techniques, safety management and contractual matters, legal and environmental issues, site investigation requirements and design methods for groundwater control schemes. The guide explains the principles and gives practical information for the effective and safe design, installation and operation of such works.
