Optimal dewatering of an excavation site by using the

Önder Değirmenci (2000) developed a management model which integrates the simulation and optimization approaches for dewatering an excavation site Their model simulates the flow process by means of a response matrix which is developed by using the outputs of the MODFLOW model The safety of the mine, slope, and dewatering wells is considered in the dewatering optimization and is partially realized in the groundwater optimization model by combining seepage discharge into an objective function and setting a constraint condition, a simple but effective treatment;Groundwater dewatering optimization in the Shengli Effective dewatering and environmental program poised to have a significant impact on the feasibility of saprolite mining operations It is therefore necessary to strike a balance between an effective dewatering program and sound environmental policy Using assessments such as rainfall, climate studies, groundwater flow, and aquifer characterizations, the Separi coal dewatering program Designs for dewatering and optimization Open
