Land Surface System

P = Q_dr + ET + W_s + R

Groundwater System

R = Q_b + L + W_g

List of Budget Components (in inches per year)

Budgets for the Toms River Basin and Metedeconk River Basin were calculated seperately in the report.

Toms River

• Precipitation (P) = 46.4
• Direct Runoff (Q_dr) = 3.4
• Base Flow (Q_b) = 18
• Evapotranspiration (ET) = 23.5
• Leakage (L) = 0.002
• Consumptive Water Use from surface-water withdraws (W_s) = 0.13
• Consumptive Water Use from unconfined groundwater withdraws (W_g) = 1.4
• Recharge to the aquifer (R) = 19.4 

Metedeconk

• Precipitation (P) = 45.9
• Direct Runoff (Q_dr) = 7
• Base Flow (Q_b) = 15
• Evapotranspiration (ET) = 23.0
• Leakage (L) = 0.00044
• Consumptive Water Use from surface-water withdraws (W_s) = 0.44
• Consumptive Water Use from unconfined groundwater withdraws (W_g) = 0.45
• Recharge to the aquifer (R) = 15
