Land Surface System

P = Qd + ET + R

Groundwater System

R = Qbf + L' + W

List of Budget Components (in inches per year)

  • Precipitation (P) = 41.9
  • Direct runoff (Qd) = 2.90
  • Base flow (Qb) = 16.40
  • Evapotranspiration (ET) = 22.4
  • Leakage out of an aquifer through a confining unit (L’) = 0.13
  • Withdrawal (W) = 0.66
  • Recharge to the water-table aquifer from the land surface (R) =  10.35
