US Department of the Interior Simulation of Tidal Flow and Circulation Patterns in the Loxahatchee River Estuary, Southeastern FloridaWater-Resources Investigations Report 87-4201 Gary M. Russell and Carl R. Goodwin ABSTRACT Results of a two-dimensional,
vertically averaged, computer simulation model of the Loxahatchee River
estuary show that under typical low freshwater inflow and vertically well-mixed
conditions, water circulation is dominated by freshwater inflow rather than
by tidal influence. The model can simulate tidal flow and circulation in
the Loxahatchee River estuary under typical low freshwater inflow and vertically
well-mixed conditions but is limited, however, to low-flow and well-mixed
conditions. Computed patterns of residual water transport show a consistent
seaward flow from the northwest fork through the central embayment and out
Jupiter Inlet to the Atlantic Ocean. A large residual seaward flow was computed
from the north Intracoastal Waterway to the inlet channel. Although the
tide produces large flood and ebb flows in the estuary, tide-induced residual
transport rates are low in comparison with freshwater-- induced residual
transport. Model investigations of partly mixed or stratified conditions
in the estuary need to await development of systems capable of simulating
three-dimensional flow patterns.
