Document Summary
Water table : a level below which the ground is saturated with water, and above which it fractured/dissolved limestone reasonably short period of time. example of aquiclude rock type: is not saturated (though moisture may be present) Fraction of a rock body consisting of void spaces (example: 20% porosity) Porosity present when the rock body is created. Porosity - created later by processes such as fracturing or dissolution. Of the saturated zone. water that falls on the land surface sinks through the unsaturated zone and becomes groundwater when it reaches the water table. material can transmit fluids. Confined aquifer: aquiclude layers. land surface without pumping. Along narrow zones of interconnected fractures exposed at the surface. Process by which groundwater exits an aquifer and enters a body of surface. Impervious cover (materials such as asphalt and concrete): water. Concentrates pollutants on top of the cover. Increases rate of runoff and worsens floods.
