| Popis: | Recently, the well-known Princeton Transport Code (PTC), a groundwater flow and contaminant transport simulator, has been coupled with the ALgorithm of Pattern EXtraction (ALOPEX), a real-time stochastic optimization method, to provide a freshwater pumping management tool for coastal aquifers, aiming in preventing saltwater intrusion. In our previous work (Proceedings of INASE/CSCC-WHH 2015, Recent Advances in Environmental and Earth Sciences and Economics, pp 329–334, 2015), the PTC-ALOPEX approach was used in studying the saltwater contamination problem for the coastal aquifer at Hersonissos, Crete. Extending these results, in the present study the PTC-ALOPEX approach is equipped with a nodal safety strategy that effectively controls saltwater front’s advancement inside the aquifer. In cooperation with an appropriate penalty system, the performance of PTC-ALOPEX algorithm is studied considering several pumping and weather condition scenarios. This study also establishes pumping/well scenarios that ensure the needed volume of fresh water to the local community without risking saltwater contamination. |
