Large Woody Debris Structures for Sand-Bed Channels

Journal of Hydraulic Engineering, 2004
Described is a method for channel erosion control and habitat rehabilitation featuring intermittent placement of structures made of large woody debris. This method is expressly tailored to address severe problems typical of incised channels with little sediment coarser than sand.

Effect of Large Woody Debris Structures on Stream Hydraulics

Wetlands Engineering & River Restoration 2001, 2001
Large woody debris structures hold promise as cost -effective stream corridor rehabilitation measures. Effectiveness of these structures placed in incised, rapidly eroding, sand -bed channels is governed by the effects of the structures on the velocity field at the toe of eroding banks.

Windthrow and recruitment of large woody debris in riparian stands

Forest Ecology and Management, 2010
Abstract To document the impacts of windthrow in riparian leave strips and identify the components needed for small stream large woody debris (LWD) recruitment modeling, we monitored nine small streams at a temperate rainforest site in coastal British Columbia.

The Role of Large Woody Debris in Beach‐Dune Interaction

Journal of Geophysical Research: Earth Surface, 2019
AbstractCoastal foredune evolution involves complex processes and controls that result from the interaction of aeolian and nearshore dynamics. No studies to date have quantified and examined the role of large woody debris (LWD) as a modulator of sediment delivery across the backshore and as a control on foredune development and maintenance.

Anchoring Methods for Large Woody Debris Structures

2003, Las Vegas, NV July 27-30, 2003, 2003
Proper anchoring of LWD structures is essential to the success of a bioengineering project. This paper covers three of the more common anchoring methods used, which include driven soil anchors, screw-in soil anchors, and cabling to boulders or bedrock. Also covered is a method for estimating the pullout capacity required of the anchor and connecting

Large Woody Debris Structures for Incised Channel Rehabilitation

Building Partnerships, 2000
Described is a project intended to restore habitats along 2 km of a sand bed stream severely damaged by channel incision. Structural measures are limited to placement of large woody debris and planting switchgrasses and woody vegetation. Assessment of pre-project channel stability and design of large woody debris structures are described. If successful,

THE RESIDENCE TIME OF LARGE WOODY DEBRIS IN THE QUEETS RIVER, WASHINGTON, USA

Ecological Applications, 2001
Instream large woody debris (LWD) provides several critical functions in riverine ecosystems, including sediment and nutrient retention, salmonid habitat enhancement, and stable colonization sites for incipient floodplain vegetation. In this study, the size and species composition of LWD in the Queets River, Washington, USA, were examined and compared ...

Distorted Froude‐scaled flume analysis of large woody debris

Earth Surface Processes and Landforms, 2001
AbstractThis paper presents the results of a movable‐boundary, distorted, Froude‐scaled hydraulic model based on Abiaca Creek, a sand‐bedded channel in northern Mississippi. The model was used to examine the geomorphic and hydraulic impact of simplified large woody debris (LWD) elements.

Environmental Hydraulics of Large Woody Debris in Streams and Rivers

Journal of Environmental Engineering, 1995
Although awareness of the habitat value of large woody debris in streams has promoted a more environmentally sensitive approach to its management, present guidelines are largely intuitive and do not contain advice for conducting quantitative hydraulic investigations.

Applying geostatistics to quantify distributions of large woody debris in streams

Computers & Geosciences, 1999
Abstract Large woody debris (LWD) strongly influences morphology and aquatic habitat in streams within forested watersheds. Previous studies have used data to describe spatial distributions of LWD in qualitative terms. We used high-resolution spatial data collected from a forested stream in western Oregon to conduct three geostatistical analyses. The
