Rancocas Creek Surficial Aquifer Study
Science Center Objects
Hydrology of the unconfined aquifer system, Rancocas Creek area: Rancocas, Crosswicks, Assunpink, Assiscunk, Blacks, and Crafts Creek Basins, New Jersey
Groundwater budget (1986-95)
Water use data (1995)
Land Surface System
P + Ras = Qdr + ET + Ws + Rn
Groundwater System
Rn + Rag = Wg + L + Qg
Where: Qg = Qb - Ras + Ws
List of Budget Components (in inches per year)
- Precipitation (P) = 47.3
- Direct Runoff (Qdr) = 6.38
- Base Flow (Qb) = 12.73
- Evapotranspiration (ET) = 25.9
- Leakage (L) = 0.5155
- Consumptive Water Use from surface-water withdraws (Ws) = 0.22
- Consumptive Water Use from unconfined groundwater withdraws (Wg) = 0.056
- Artificial recharge to the surface-water system (Ras) = 0.83
- Artificial recharge to the unconfined groundwater system (Rag) = 0.1
- Natural recharge to the aquifer (Rn) = 14.1
- Groundwater discharge (Qg) = 12.1
