GEOL 100 Chapter Notes - Chapter 17: Losing Stream, Vadose Zone, Unconformity
Document Summary
17. 5 what is the relationship between surface water and. Surface water and groundwater are not isolated systems. How the water moves between surface and subsurface. If the surface material is permeable and the water table is deep enough that there is an unsaturated zone, surface water can soak into the subsurface and become groundwater. Groundwater recharge: percolation of water into the groundwater helps replenish water lost by wells, springs, or other parts of the system. When the water table intersects with the surface, groundwater can flow into the land, becoming surface water. A spring represents a place where groundwater flows out of the ground onto the surface. At most springs, the water table intersects the surface. Can occur in a variety of geologic settings. What causes groundwater to emerge as a spring: Faults serve as conduits for groundwater that feeds springs. Most faults are zones of intense fracturing (permeable)
