Effect of Well Distribution on Dewatering Design for Regular and Irregular Wells Using MATLAB Software

Abstract

The groundwater control is one of the initial geotechnical procedures performed on the site; therefore, before beginning any excavation, it is required to study site condition and hydrological state. Using MATLAB software created a program to design a dewatering system named DDS2021 to control the groundwater level before construction .it's presented the distribution of wells for the regular and irregular areas and presented the graphical shape of the water table drawdown induced by water extraction for all wells. Dupuit’s assumption is the base for representing the dewatering curve. It may be possible to achieve the required lowering for the groundwater in the proposed pit by using a few wells pumped with high flow rates or a more significant number of wells with low flow rates. Similarly, varying the well locations surrounding (or within) the excavation may result in significantly different drawdowns in the area study. This search studied the effect of the regular and irregular distribution pattern wells on the lowering of groundwater levels for both regular and irregular areas.
