  1. Water Balance Components

  2. http://www.srs.fs.usda.gov/gallery/images/5_rain_gauge.jpg

  3. DBHydro • State Plane Coordinates • High Accuracy Reference Network (HARN) • Refinement of NAD83

  4. DBHydroRainfall Stations • Approximately 600 stations

  5. Spatial Distribution of Average Rainfall http://sflwww.er.usgs.gov/sfrsf/rooms/hydrology/compete/obspatialmapx.jpg

  6. Voronoi/Thiessen Polygons

  7. Evaporation Pan www.photolib.noaa.gov/ historic/nws/wea01170.htm

  8. Pan Evaporation • Pan Coefficients: 0.58 – 0.78 (get hotter than lake) • Transpiration • Potential Evapotranspiration (water may not be in soil) • Thornwaite Equation

  11. Stage

  12. Stage Recorder http://gallatin.humboldt.edu/~brad/nws/assets/drum-recorder.jpg

  13. Stream Gauging • Measure velocity at 2/10 and 8/10 depth • Q = v*A • Rating curve: • Q vs. Stage http://www.co.jefferson.wa.us/naturalresources/Images/StreamGauging.jpg

  14. River Hydrograph http://cires.colorado.edu/lewis/epob4030/Figures/UseandProtectionofWaters/figures/ColoradoRiverHydrograph.gif

  16. Recurrence Interval • T = n+1 /m • T: recurrence interval • n: number of data • m: rank (highest to lowest) • P = 1/T • http://serc.carleton.edu/quantskills/methods/quantlit/RInt.html
