Abstract

In British Columbia (BC), Canada, and Washington State, USA, anchored Large Woody Debris (LWD) have been extensively used with the specific aim of reducing erosion and limiting wave run-up. Despite its frequent usage, there is currently limited peer-reviewed literature on the design or efficacy of coastal protection using LWD. This paper presents the results of the first systematic research project on this topic, which involved (1) extensive field investigations of existing anchored LWD projects, and (2) large-scale experimental wave modeling of simulated LWD on a gravel beach. The full paper will present an overview of the study methodology, field investigation and experimental modeling results, and provide initial design guidance for the use of coastal protection using anchored LWD.
