Wave Modeling for Jetty Rehabilitation at the Mouth of the Columbia River, Washington/Oregon, USA

Abstract

The U.S. Army Engineer District, Portland (NWP), maintains three rubble-mound jetties at the Mouth of the Columbia River (MCR) in support of the Federal navigation project. The north and south entrance jetties constrain the current to scour the navigation channel, stabilize the location of the channel and entrance, and provide wave protection to vessels transiting the MCR. A third jetty (Jetty A) inside the MCR serves primarily as a training structure for the navigation channel to direct the flow away from the foundation of the north jetty. The jetties have significantly degraded during the past several decades. A maintenance plan is being developed to manage the jetties at the MCR to best support the Federal navigation project.
