A flow-simulation model of the tidal Potomac River
Raymond W. Schaffranek
1987, Water Supply Paper 2234-D
A one-dimensional model capable of simulating flow in a network of interconnected channels has been applied to the tidal Potomac River including its major tributaries and embayments between Washington, D.C., and Indian Head, Md. The model can be used to compute water-surface elevations and flow discharges at any of 66...
