Filtering the signature of submerged large woody debris from bathymetry data

Journal of Hydrology, 2005
Modeling water velocities and depth for riverine aquatic habitat analysis requires fine-scale surveys of river bathymetry. The presence of submerged large woody debris (LWD) distorts the results of acoustic bathymetry surveys and subsequent modeling if the LWD data is not separated from the background river bathymetry.

Experimental provision of large woody debris in streams as a trout management technique

Aquatic Conservation: Marine and Freshwater Ecosystems, 2002
Abstract The natural stock of large woody debris (LWD) in the afforested Douglas River (Fermoy, Co. Cork) is very low relative to old‐growth forests, which seems to arise from deficiency both of supply and retention. Woody debris is important to the ecology and physical structure of forest streams, so its abundance is relevant to aquatic conservation ...

Quantity, controls and functions of large woody debris in Midwestern USA streams

River Research and Applications, 2006
AbstractLarge woody debris (LWD) can increase stream habitat heterogeneity by providing structure, altering flow patterns, enhancing sediment deposition, forming pools and retaining organic matter. In North America, the role of LWD has been studied extensively in streams of mature forests (e.g.

Dynamic aspects of large woody debris in river channels

2014
The research work has been dedicated to the analysis of some aspects of wood behavior and to the development of effective tools to perform hazard analysis in the perspective of a comprehensive approach to the hydraulic risk assessment. The dynamical processes of wood in river reaches: a) production and recruitment; b) entrainment and transport; c) halt

SIMULATING CATASTROPHIC AND INDIVIDUALISTIC LARGE WOODY DEBRIS RECRUITMENT FOR A SMALL RIPARIAN SYSTEM

Ecology, 2000
Surprisingly little research has been done to partition the contribution of catastrophic disturbance from that of small-scale individualistic mortality events on riparian large woody debris (LWD) recruitment. This study compared the impact of both processes on recruitment through simulation of several catastrophic disturbances (a spruce beetle outbreak,

Interest of large woody debris in fish habitat

1998
Large Woody Debris (LWD) are important physical structures within fish habitat. Their role for fish was largely demonstrated in the litterature for low order stream in North America characterized by Salmonids. Studies dealing with multispecies communities and large rivers are rare and need to be conducted.

Large woody debris influences vegetation zonation in an oligohaline tidal marsh

Estuaries and Coasts, 2007
The amount of large woody debris (LWD) in Pacific Northwest estuaries has declined dramatically since Euro-American settlement in the mid 19th century. Little is known about the ecological significance of estuarine LWD. This ignorance impairs protection and restoration of habitat critical to threatened Chinook salmon (Oncorhynchus tshawytscha), as well

Large woody debris fish habitat structure performance and ballasting requirements

2009
Many stream restoration efforts include placement of constructed large woody debris (LWD) habitat structures. These structures are installed in stable channels to rehabilitate summer habitat and critical overwintering refuges in streams, thus attenuating stresses on the aquatic ecosystem until logged riparian areas naturally supply mature windfalls ...

Large CO2 removal potential of woody debris preservation in managed forests

Limiting climate warming to 1.5 °C requires reductions in greenhouse gas emissions and CO2 removal. While various CO2 removal strategies have been explored to achieve global net-zero greenhouse gas emissions and account for legacy emissions, additional exploration is warranted to examine more durable, scalable and sustainable approaches to achieve ...
