A genetic algorithm is used to select the location and timing of sampling events. A Kalman filter is used in the algorithm to obtain the best estimate of the concentration field. The use of a Kalman filter requires an initial estimate of the concentration field. This is achieved as the output of a groundwater flow and transport simulation model. One input to the simulator, observations of the hydraulic conductivity field, are generated using a Latin-hypercube sampling (Lhs) technique. The use of this Lhs technique reduces the number of times one solves a groundwater flow and transport problem in a Monte Carlo approach. The combination of all of these technologies provides an efficient groundwater sampling network design. The proposed methodology is applied to a field problem. Results show the methodology is applicable and cost-effective. They also suggest that better estimates are achieved if sampled field data are utilized in an interactive sampling-network design strategy.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202312714\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786202312714","offer_id":40149980381277,"sku":"9786202312714","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7a274e1c-deaf-4cb0-bcbc-208ea3a08fed.jpg?v=1774509662","url":"https:\/\/shop.autorenwelt.de\/products\/optimal-design-of-groundwater-quality-monitoring-network-von-yingqi-zhang","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
