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 Mitigation

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

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 ...

Homogenization of regional river dynamics by dams and global biodiversity implications

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...

State-of-the-Science Review: Gravel Mitigation and Augmentation Below Hydroelectric Dams: A Geomorphological Perspective

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

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 ...

2004 STREAM Strategic Planning Workshop Summary

John Potyondy, Program Manager

The STREAM Strategic Planning Workshop was held on March 30-31, 2004 in Fort Collins, Colorado. The primary objective of the workshop was to review the National Stream Systems Technology Center (STREAM) work plan and charter with the intent of looking ahead at nationally significant emerging issues and evaluate opportunities for STREAM to address and provide relevant technology to meet anticipated needs.

Workshop on the Multiple Influences of Riparian Ecosystems on Fires in Western Forest Landscapes - Summary Report

J. Boone Kauffman

This report summarizes discussions from "The Workshop on Multiples Influences of Riparian/Stream Ecosystems on Fires In Western Forest Landscapes" sponsored by the Stream Systems Technology Center and held at the Center for the Management of Information, University of Arizona, Tucson AZ, March 13-15, 2001. A diverse group of 30 federal scientists, fire and natural resource mangers, and university professors convened to discuss the functional role of riparian/stream zones as they affect fire on western forest landscapes.

Still No Water for the Woods

Lois G. Witte

This paper examines the federal government's track record in securing instream flows and protecting aquatic resources on federally reserved lands in the West, using lands administered by the Forest Service as an example.

A Bank-Operated Traveling Block Cableway for Stream Discharge and Sediment Measurements

James J. Paradiso (General Technical Report RMRS-GTR-RM-000. 1999)

File: Cableway.zip (1.2 KB)

This publication describes the construction and use of a cableway system. Included are figures describing parts and dimensions, installation methods, and field operation. The system provides a low-cost, safe alternative to cable cars or operation from bridges during high runoff.

This zip file only needs to be downloaded by anyone wishing to construct a traveling block cableway as described in RMRS-GTR-44. The zip file contains a full-sized set of scaled AutoCAD plans (*.dwg format) and standard graphics files (*.tif format) as described in Appendix B of the publication. File notation corresponds to the figures in the publication (e.g. file "cable04.tif" refers to Figure 4). AutoCAD software is needed to look at the *.dwg files.
