Land Surface System

P + Ras = Qdr + ET + Ws + Rn

Groundwater System

Rn + Rag = Wg + L + Qb

List of Budget Components (in inches per year)

  • Precipitation (P) = 45.4
  • Direct Runoff (Qdr) = 6.3
  • Base Flow (Qb) = 13
  • Evapotranspiration (ET) = 26
  • Leakage and flow to unconfined aquifers (L) = 0.007
  • Consumptive Water Use from surface-water withdraws (Ws) = 0.107
  • Consumptive Water Use from unconfined groundwater withdraws (Wg) = 0.136
  • Artificial recharge to the surface-water system (Ras) = 0.035
  • Artificial recharge to the groundwater system (Rag) = 0.112
  • Natural recharge to the aquifer (Rn) = 13.03
