Document Summary

Water balance for a system with storage. Water balance equation for a defined hydrologic system: Inflow - outflow = change in storage. Conservation of mass (for time period t): flow pathways and storage components. The hydrological continuity equation for any system is: I - q = ds / dt. Sink: flux in > flux out = accumulation. Source: flux out > flux in = loss. (p + q in + gw in ) - (q out + et + gw out ) = s s + s sm + s g. Conceptually very simple accounting of water in and water out of the catchment or control. The difficulty comes in unequivocally measuring or estimating the components. Accurately balancing the water budget is not trivial. For any hydrological system, a water budget can be developed to account for various. Net amount of gain or loss of water in a system during a given time period.
