Print on Demand. This book explores the historic and ecological use of engineered logjams to protect riverbanks from erosion. Engineered logjams—a form of river engineering—emulate natural logjams that have historically created stable and biologically productive structures in river systems. Historically, the technology has been used to prevent damage to roads and bridges. The author presents conceptual designs and engineering cost estimates for a case study in Alaska. They also provide guidelines for designing and constructing these structures in a way that not only protects riverbanks but also enhances aquatic habitat. By presenting environmental and economic benefits, this book establishes engineered logjams as a viable alternative to traditional river engineering practices. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

This technical memorandum summarizes an assessment of the applicability of engineered logjam technology to protect the Dyea town site along the western bank of the Taiya River from continuing erosion. The site is located in Klondike Gold Rush National Historical Park.
Channel migration of the lower Taiya River threatens the historic town site of Dyea, located in southeastern Alaska about 10 miles northwest of Skagway (figure l). The Taiya River in the Dyea vicinity has been migrating to the west since the 19603 (inglis and Pranger Bank erosion has destroyed approximately 50 percent of the Dyea town site at its northern end. The Klondike Gold Rush National Historical Park would like to protect the cultural resources of Dyea without adversely affecting the natural resources of the Taiya River. The National Park Service (nps) is investigating engineered logjam technology as a potential strategy to stabilize the eroding river bank and cease the ongoing loss of land at the Dyea town site. Traditional bank protection such as rock revetments can limit erosion when correctly applied but have negative environmental impacts and alters the natural and historic character of the river which the nps would like to preserve. This technology has the advantage of protecting both cultural and natural resources when properly applied in appropriate settings.
This technical memorandum describes engineered logjam technology, provides a brief geomorphic assessment of the lower Taiya River, determines the feasibility of an engineered logjam bank protection strategy at Dyea, and provides conceptual designs and engineering cost estimates for such a strategy.
