Introduction
to Engineered Log Jam Technology and Applications for Erosion
Control and Fish Habitat
Course
ID: HYD-501
September 18 - 22, 2006, 8:30 A.M. to 5:00 P.M. (5 Days)
Quileute Ocean-Side Resort
*Note: Participants will meet in Seattle at NWETC Headquarters (directions link above) for a short lecture then load vans and travel to the Olympic Peninsula. We will be staying in cabins on the beach, attending lectures, and going on field trips throughout the week. Registration includes transportation, all meals, and accommodations - each participant will have their own room.
Course Description: Engineered log jam (ELJ) technology offers an important tool for restoring fluvial ecosystems and solving traditional river management problems such as bank protection, debris retention, and grade control. This class will provide an overview of the principles, potential applications, and limitations of ELJ technology; spending approximately half the time in the field examining both natural and engineered log jams. The class will begin with a description of the characteristics and processes of natural wood accumulation and end with examples of how ELJ structures have performed, and an overview of design elements and costs.

*Several field trips will be taken during the week, including hikes to natural log jams, constructed valley jams, and the world's largest ELJ project on the Hoh River.
Participants will finish with an understanding of the following:
Intended Audience: Managers in public work restoration such as transportation, surface water, flood protection, watershed management, and river professionals seeking a solid understanding of potential applications of ELJ technology applications.
Prerequisites: Experience in river management / restoration is required. Working knowledge of fluvial geomorphology, engineering mechanics, and open channel flow is helpful but not required.
