Aquifer Heterogeneity and Anisotropy: Confined, unconfined, and hybrid confined/unconfined domains. Confined interface, and unconfined interface aquifers for fresh/salt interfaces. Anisotropy in the horizontal may very in ratio and direction from one domain to the next.

Review this model, download it, and play with it to learn how to apply AnAqSim to dewatering problems. This is a model of a complex dewatering system that includes a partially-penetrating circular sheet pile barrier, three shallow wells pumping inside the barrier, and a shallow recharge trench outside the barrier, where the discharge of the wells is put back into the aquifer. The aquifer is unconfined and sandy, with about 120 ft of saturated thickness. The system will allow excavation 10 ft below the ambient water table within the barrier to install a tank. The figure at right shows a map of the system elements. The sheet pile wall is 63 ft in diameter and it penetrates 30 ft below the water table. The pumping wells are screened in the upper 20 ft of saturated thickness and are 6 inches in diameter. The recharge trench introduces water into the uppermost part of the saturated zone and is 116 ft long.
