Current meter time series recorded simultaneously at three study sites along
the Atlantic Intracoastal Waterway (AIW) are used to characterize tidal and nontidal flow in
the northern sub-basin of Florida's Indian River Lagoon near Sebastian Inlet. The semi-diurnal
M2 constituent dominates all other tidal constituents with amplitudes decreasing from 11.0 cm
s⁻¹ near the inlet to 7.6 cm s⁻¹ 13 km north. The relative importance of the tidal variance in
the current meter records decreases from 49% to 33% of the total over the same distance. The
propagation of the M2 tidal wave is 5.5 km hr-1, based on phase angle and distance relationships
between two of the study sites. Net along-channel flow is to the south, or towards the
inlet, ranging between 0.5 and 2.1 cm s⁻¹ in this section of the AIW during the 42-day study.
Low-frequency motions at all three sites are inversely related to wind stress.
