Abstract
Integrated nearshore currents composed of longshore and circulation currents were tested against the continuity of water mass equation (Galvin and Eagleson, 1965), for a dissipative, barred transect of Guyana's Batchelor's Adventure beach. Although there were considerable variations in beach energy conditions during the study period, good agreement (r$\sp2$ =.536) between observed current velocity and those predicted by the model was established. Considerations of daily wave conditions and especially topographical parameters provided accurate estimates of the flow velocity where currents were being forced alongshore. In addition, the current distribution displayed considerable spatial heterogeneity probably because of varying wave, water and topographical parameters. Bimodal, coast-normal distributions were present, and greatest velocities were observed closest to the breaker zone. Spectral analysis of the current flow indicated that considerable white noise was present in the series. However, the existence of spectral energy peaks at or near the incident wave frequency were satisfactorily demonstrated.Dept. of Geography.
