Large in-stream wood studies: a call for common metrics


Ellen E. Wohl, Daniel A. Cenderelli, Kathleen A. Dwire, Sandra E. Ryan-Burkett, Michael K. Young, Kurt D. Fausch

During the past decade, research on large in-stream wood has expanded beyond North America's Pacific Northwest to diverse environments and has shifted toward increasingly holistic perspectives that incorporate processes of wood recruitment, retention, and loss at scales from channel segments to entire watersheds. Syntheses of this rapidly expanding literature can be facilitated by agreement on primary variables and methods of measurement. In this paper we address these issues by listing the variables that....

References for Channel Incision and Headcut Mitigaton


Compiled by Gabrielle David

This bibliography contains various publications on channel incision and headcut mitigation techniques. The bibliography is based on an initial literature review of peer-reviewed journals, government documents, books, and grey literature on channel incision and headcut mitigation. Particular attention was paid to those documents that focused on 1) applying a geomorphic approach to developing techniques for the rehabilitation of incised channels and 2) mitigation techniques used to stabilize headcuts. This bibliography is a work-in-progress and will be updated periodically...

Comparison of Three Pebble Count Protocols (EMAP, PIBO, and SFT) in Two Mountain Gravel-Bed Streams

Kristin Bunte, Steven R. Abt, John P. Potyondy, and Kurt W. Swingle

Although the term ‘‘pebble count’’ is in widespread use, there is no standardized methodology used for the field application of this procedure. Each pebble count analysis is the product of several methodological choices, any of which are capable of influencing the final result. Because there are virtually countless variations on pebble count protocols, the question of how their results differ when applied to the same study reach is becoming increasingly important. This study compared three pebble count protocols...

 

Theory, methods and tools for determining environmental flows for riparian vegetation: riparian vegetation-flow response guilds (137 KB / 20 pages)

David M. Merritt, Michael L. Scott, N. Leroy Poff, Gregor T. Auble and David A. Lytle

Theory, methods and tools for determining environmental flows for riparian vegetation: riparian vegetation-flow response guilds". The first paragraph in the summary is " Riparian vegetation composition, structure and abundance are governed to a large degree by river flow regime and flow-mediated fluvial processes. Streamflow regime exerts selective pressures on ...

RMRS-GTR-226: Sediment transport primer: estimating bed-material transport in gravel-bed rivers (1440 KB/84 pages)

Peter Wilcock, John Pitlick, and Yantao Cui

This document provides background information on sediment transport dynamics and is a supplement to the BAGS (Bedload Assessment in Gravel-bedded Streams) program so that the user can more effectively apply the model and interpret the bed load transport estimates. Additionally, the document provides information to help the user of BAGS define relevant and proper sediment transport problems, select appropriate model input data, interpret and apply the model output results in a useful and reliable fashion, and examine sources of error.

Homogenization of regional river dynamcs by dams and global biodiversity implications (2020 KB / 6 pages)

N. LeRoy Poff, Julian D. Olden, David M. Merritt, and David M. Pepin

Global biodiversity in river and riparian ecosystems is generated and maintained by geographic variation in stream processes and fluvial disturbance regimes, which largely reflect regional differences in climate and geology. Extensive construction of dams...

A Geomorphic Perspective on Things to Think About Before
Starting a Gravel Augmentation Project

Kristin Bunte, John Potyondy, and Dan Cenderelli

Gravel augmentation for the purpose of spawning habitat improvement has been carried out episodically by various government agencies since the 1960’s, and renewed interest in gravel augmentation was generated during the relicensing of numerous hydroelectric projects in the 1990’s. From a scientific and engineering perspective, not much ...

 

State-of-the-Science Review: Gravel Mitigation and Augmentation Below Hydroelectric Dams: A Geomorphological Perspective (2595 KB / 144 pages)

Kristin Bunte

In many salmon-bearing Pacific coast gravel-bed rivers, closure of hydroelectric dams cut off gravel supply to streambeds below. Gravel mining and changes in the post-dam flow regime further disturbed the streams, leaving them in a geomorphologically and biologically dysfunctional state. Habitat for spawning and other salmon life stages ...

 

Hydrologic Regimes and Riparian Forests: A Structured Population Model for Cottonwood (99KB / 11 pages)

David A. Lytle and David M. Merritt

Riparian cottonwood (Populus deltoides) forests form the one of the most extensive deciduous forest ecosystems in arid regions of the western United States. However, cottonwood populations are threatened by flow alteration and channel degradation caused by dams, water diversions, and groundwater pumping. We developed a ...

 

RMRS-GTR-128: Quantifying Channel Maintenance Instream Flows: an approach for gravel-bed streams in the Western United States (1420 KB/42 pages)

Larry J. Schmidt and John P. Potyondy

This paper discusses one approach for quantifying channel maintenance instream flow necessary to achieve the Forest Service Organic Act purpose of securing favorable conditions of water flows. The approach is appropriate for quantifying channel maintenance flows on perennial, unregulated, snowmelt-dominated, gravel-bed streams with alluvial reaches. The approach identifies the minimum essential regime of streamflows necessary for the channel and its floodplain to...
