How does water move through Earth’s layers? Use the model templates to explore the differing permeabilities of different sediment types, drill wells into model landscapes, explore the difference between confined and unconfined aquifers, discover how water moves around gaining and losing streams, and explore the difference between rural and urban area aquifers. Create your own landscapes to test ideas about water movement and sustainability of wells. Use the graphs to measure the amount of water from each well and monitor the level of water in streams.
