  1. CP Water Balance and Physical Hydrology 1/26/2012

  2. Fluxes of water

  3. Water flux between NWT and CP Preliminary ET flux results: WY2010: NWT=0.66 m ET/P=0.83 CP=0.67 m ET/P=? WY2011: NWT: 0.55 m ET/P=0.62 CP: 0.69 m ET/P=0.54 Pcp=128 cm? Pnwt=88 cm Pnwt=80 cm

  4. Timing of Response

  5. Daily dynamic storage of water • Bied culvert: • Starting storage=175 mm • Ending storage=148 mm • Max dV=300mm • Bear Creek • Starting storage=200 mm • Ending storage=240 mm • Max dV=300 mm Discharge exceeds storage Threshold in the beaver ponds Growing-season Storage release Snow season storage release Discharge exceeds P (water previously in the Catchment is being released)

  6. Sources of water to the stream

  7. Partitioning of E and T • MWL

  8. Future research question hypothesis • Can we quantify vaporization from snow and evaporation from soil in the total ET response? • Do these compensating factors (snow sublimation and soil evaporation) explain the magnitudes of ET flux observed in healthy and dead stands? • How do hillslope storage processes lead to downslope excess water and potentially higher ET?
