Land Surface System

P + Ras = Qdr + ET + Ws + Rns

Groundwater System

Rng + Rag + Ri = Wg + L + Qb

Qg = Qb - Ras + Ws

Ri = Rng - Rns

List of Budget Components (in inches per year)

  • Precipitation (P) = 44.7
  • Direct Runoff (Qdr) = 3.9
  • Base Flow (Qb) = 15.9
  • Evapotranspiration (ET) = 23.4
  • Leakage (L) = 0.22
  • Groundwater discharge (Qg) = 25.1
  • Consumptive Water Use from surface-water withdraws (Ws) = 0.019
  • Consumptive Water Use from unconfined groundwater withdraws (Wg) = 0.404
  • Artificial recharge to the surface-water system (Ras) = 0.114
  • Artificial recharge to the unconfined groundwater system (Rag) = 0.125
  • Natural recharge to the aquifer (Rns) = 17.5
  • Natural groundwater recharge to the aquifer (Rng) = 25.6
  • Groundwater inflow (Ri) = 8.1
