<br/><br/> Deep wells dewatering systems are usually used in case of deep excavation under groundwater table levelVertical cutoff walls may be used to increase the efficiency of the dewatering system , to reduce the negative effect of the dewatering process on adjacent structures , and / or to serve as a side support systemHowever , the dewatering system composed of deep wells and partially penetrating cutoff walls , and penetrate unconfined aquifer is considered a complex system , which cannot be designed using equilibrium formulas
