Wave-Current Conditions and Navigation Safety at an Inlet Entrance

Abstract

The narrow jetty configuration of Tillamook Inlet functions to constrict tidal flow, increase current speed, and prevent sediment deposition. However, the interaction of strong currents with incoming ocean waves over the inlets ebb shoal can amplify and complicate the wave environment at the inlet entrance. In this study, the Coastal Modeling System (CMS) was used to investigate time- and space-varying wave and current conditions affecting boating operations at Tillamook Inlet and quantify the effects of physical processes. Wave simulations with refraction, shoaling, and breaking provide estimates of wave-related parameters of interest to the navigable region at Tillamook.
