The literature currently includes several studies regarding the solution of dewatering optimization problems. Aguado et al. proposed a method for designing a dewatering system for a site. Their simulation model consists of the finite difference solution of the governing PDE, which is embedded as a constraint in a linear-programming-based optimization model.
