Abstract:
The WASP5
hydrodynamics model DYNHYD5 is an update of DYNHYD4 (Ambrose et.al
1988), which was an enhancement of the Potomac Estuary hydrodynamic model
DYNHYD2 (Roesch et al. 1979) derived from the original Dynamic Estuary Model
(Feigner and Harris, 1970). DYNHYD5 solves the 1-dimensional equations of
continuity and momentum for a branching or channel-junction (link-node),
computational network. Driven by variable upstream flows and downstream
heads, simulations typically proceed at 1 to 5-minutes intervals. The
resulting unsteady hydrodynamics are averaged over large time intervals
and stored for later use by the water quality program.
