Groundwater & Wetlands. Water gain within a watershed is the balance of precipitation and evapotranspiration. Groundwater: Subsuface water below the water table , which is the depth where soil becomes water saturated (i.e. all pore spaces are water filled).By jonathanross

Running Water & Groundwater. Chapter 6. Mr. Litaker. The Water Cycle. Water constantly moves from the oceans to the atmosphere to the solid Earth and throughout the biosphere. Why? * Because water can change b/w a solid, liquid, and a gas. Look at Figure 1 on page 158
Surface water / Groundwater Interaction. Conjunctive use and conjunctive management. Key Issues for GW-SW Interaction. Physical / Chemical Interaction – water balance / quality implications System Dimensions: time / flow rate factors River basin / aquifer boundaries Allocation issues

Water Cycle and Groundwater. Chapter 9. Draw a picture below of what you remember of the water cycle:. Now examine page 185 in the workbook and add on any new terms to your diagram above (or draw a new one below).
Surface Water and Groundwater. Fusion Text: Pages 30-38. Where on the Earth is fresh water found?. On the Earth’s Surface ( Surface Water ) Beneath the Earth’s surface ( Groundwater ). On the Earth’s Surface ( Surface Water ) Streams, Rivers, and Lakes.

Running Water and Groundwater. Oceans – 97 % Glaciers/ice – 2 % Freshwater - < 1 % Water cycle = the continuous circulation of earth’s water supply It is powered by the sun. Evaporation = liquid to gas Condensation = gas to liquid (forms clouds)
Water Use and Groundwater. Supply is Dwindling, Demand is increasing. population growth industrial development expansion of irrigated agriculture. Industry uses 20-25 percent of available freshwater. Irrigation for crops uses 65- 70 percent of fresh supplies.
