- 1reservoir vs fluxreservoir: size of something(mass or volume)(2,000gal)
flux is flow of a quantity into of out of reservoir(i.e. 6gal/hr) - 2% evaporated from ocean returns to ocean385/425
- 3hydrologic cycle
- 4how much evaporated water from land returns to land111/71(136%(36% comes from ocean))
returns via ground flow to ocean to even it out - 5how much water on earth is in the ocean96.5% in ocean
- 6major sources of freshwaterfreshwater(2.5%) glaciers(68.7%), groundwater(30%) surface(1.2%)
- 7water usage in worldagriculture(70%), municipal(11%), industrial(19%)
- 8how much irrigation water do NC used per day vs california~1000(NC) 15000-19000(california)
- 9which countries use over 75% of their sustainable watermiddle east area mostly
- 10top of groundwaterwater table
- 11how is groundwater replenishedpercolation(rainfall)
- 12how much groundwater extracted in US/person~100,000gal/year
- 13how is groundwater found in earthin fractured rock, soil, and gravel
- 14where are streams and lakes replenished in humid areasb
- 15climate change impact on groundwaterhigher temps mean greater evapotranspiration, more water needed for ag, water in aquifers reduced
could have more precipitation
temp of oceans less increase in temp than land(take longer to warm up) - 16RCP 6.0 graphlook on slides
NC percip increase 0-10% in 2100 - 17circulation cell diagram
- 18palmer drought severity indexmeasurement of dryness based on recent precip and temp
4 = extremely wet
-4 = extreme drought
0 = near normal - 19which 2 states had severe or extreme drought for more than 20% of 1895-1995Colorado and Wyoming
- 20when was dustbowl palmer index in kansas and nebraska1930s -4 palmer index in most of the midwest
- 21permafrostsoil remains below 0C for 2 or more years(can be below surface doesn't have to be frozen always at surface too
- 22where in us most permafrostalaska(around 85% of soil) extends as much as 2000 ft below surface
- 23name of 3 layrs of soil containing permafrostactive layer, permafrost, talik
plants can be found in active layer - 24organic soil in permafrost vs world50% in permafrost if melts would release CO2 and CH4
