Daily Review #2 6. What two factors affect groundwater? 7. How does the pumping out of water in a well effect the water table and why? 8. What is the Ogallala Aquifer and why is it important? 9. What do discharge and recharge mean? End

Surface Water Lakes, rivers, streams, etc. From precipitation Runoff Infiltration, eventually Watershed or Drainage Basin Divides Headwaters Colorado is a headwater state

Streams (Rivers) Definition Groundwater meets surface and runoff Flow downhill Carries sediment Faster water = larger sediment Agent of erosion Tributaries Creeks

Landforms made by Erosion Stream channel Meander Ox bow lakes

V-shaped valley Waterfalls Deltas Floodplain Good farmland

Daily Review #3 10. How do rivers and streams form? 11. Define watershed, delta, ox bow lake, floodplain and tributary and divide 12. Why is Colorado considered a headwater state? 13. When it rains in Parker, where does the water eventually end up? End

Water Pollution Types Sediment Nutrients/chemicals Pathogens Point Nonpoint Fertilizer Algal blooms Eutrophication Erosion

Fixing Pollution Clean Water Act (1972) Reduce, reuse, recycle Limit fertilizers Limit erosion Changes in agricultural practices Barriers during construction, mining, etc. Decrease usage

Ocean Issues Why is the ocean important? Ocean issues Trash dumping Sludge dumping Oil spills Excessive fertilizer use Coral bleaching

Desalinization Process Distillation Reverse osmosis Energy intensive

Urban Water Extraction Groundwater Decreased infiltration Surface water Water rights Distribution Treatment Filtering Biological agents Sludge disposal Reuse Use of grey water
