Speaker : Sreejith Pulloor Kuttanikkad Abstract: Modeling, Simulation and Optimization in Practice: An application from Ground Water Engineering In this talk, I would like to give a brief account of how modeling simulation and optimzation plays a big role in real world engineering problems and in particular I would describe an application from ground water engineering namely groundwater problem associated with open-pit mining activities. Opencast mines operating in an area with dominant groundwater features may face hydrology related problems such as heaving and bursting of the mine floor due to excessive uplift pressure. A proper groundwater control system has to be implemented to solve such problems. But the groundwater control system, which include dewatering and depressurization wells may also create impacts on the local groundwater flows. Therefore, an optimization-based development of groundwater control system is required to ensure that local and regional hydrological impacts are within acceptable limits. Groundwater engineers involved in such open pit mining activities extensively make use of numerical modeling of such complex systems to simulate the different groundwater scenarious and to assist in developing optimal pumping plans. The talk is not intended to give every details of modeling, simulation and optimization of the given problem, but to introduce the very interesting and challenging problem to the audience and address how in practice the problem is being solved using the techniques of modeling, simulation and optimization.
