THE DESIGN OF A "ROLLING" GROUNDWATER CONTROL SYSTEM

A "rolling" dewatering system is defined as two parallel lines of wells installed at a range to match the movement of the centre of construction for which dewatering is required. As the centre of construction moves forward the first wells installed are gradually shut down as they become more distant from the centre of dewatering. This kind of dewatering installation is useful for construction of sewers, canals, tunnels, etc., where a high water table exists. A program is written for the hand-held programmable t15 calculator, which predicts the performance of such dewatering installations. It is shown that, depending on the diffusivity (t/s) of the aquifer, spacing between wells can be gradually increased as time progresses and economies in dewatering costs can be made. Criteria are developed to a dewatering system required for the construction of a canal in Bangladesh. (Author/TRRL)
