Websummer. By using permeable surfaces, which allows percipitation to trickle through, for driveways, patios, parking areas and roads, the effects of development on water quality, erosion and groundwater levels can be reduced. Permeable surfaces are typically used for low-traffic, low-load areas, such as pathways and patios whereas permeable WebGroundwater Movement Students explore how porosity and permeability of different sediments affect the way water flows through Earth's layers. Students use interactive computational models to explore the underground flow and deposition of water and determine the best places to access the water in a sustainable manner.
