Review on thursday after reviewing quiz 3, and then friday we(cid:495)ll do a more comprehensive review; what(cid:495)s the exam format etc. Runoff (renewable flow: amount & timing of runoff will change according to changes in temp, and precipitation regimes. Groundwater: reduced rates of infiltration overall. Recharge depends on the timing and rates of precipitation inputs to soils, and the rates of evapotranspiration. High intensity storms lead to less recharge than a constant sprinkle. High rates of evapotranspiration reduce percolation to groundwater: greater stress on groundwater because of more intense storms and more evapotranspiration. Effect on sea level (direct effects: melting of ice on land (glaciers an ice sheets, warming causes sea water to expand; Changes in precipitation and temperature lead to changes in runoff and water availability.
