Book excerpt: The analytical method presented herein, developed through the Flood Control Channels Research Program, is intended for use to estimate channel dimensions for preliminary design studies. It accounts for the movement of sediment and for varying roughness due to changing bed forms. It also attempts to account for the effects of bank roughness that can be significant in small channels and is essentially neglected in many approaches that assume wide channels. This analytical approach determines dependent design variables of width, slope, and depth from the independent variables of discharge, sediment inflow, and bed material composition. It is especially applicable to small streams because it accounts for transporting the bed material sediment discharge in the water above the bed, not the banks, and because it separates total hydraulic roughness into bed and bank components. A stability analysis can be done by first determining the bed material sediment load entering the project reach, and then analyzing the family of slope-width solutions that satisfy the resistance and sediment transport equations. The resulting stability curve provides many combinations of slope and base width, all of which will be stable for the prescribed channel design discharge. Combinations of width and slope that plot above the stability curve will result in degradation, and combinations below the curve will result in aggradation. The greater the distance from the curve, the more severe the instability. Alluvial streams, Sedimentation, Flood- control channels, Stability analysis, Sediment transport, Stable channels.

Book excerpt: This volume was written to describe how to carry out an analysis of a channel stability problem. Therefore it is rather general; only the last chapters describe problems of channel stability in the Yazoo River Basin. Detailed reports of the various research projects associated with this study of channel stability problems in the Yazoo River Basin are presented as Appendices. They are completely independent reports. The overall research program had five major objectives: (1) Determining the influence of grade control structures on channel stability; (2) Monitoring the performance of selected channel stabilization methods; (3) Evaluating the effects of geology, geomorphology, soils, land use, and climate on runoff and sediment production from major source areas; (4) Estimating the water and sediment production from a large, mixed-land-use watershed and the integrated effects on channel stability; and (5) Evaluating the relation between valley stratigraphy and channel morphology and their combined effects on channel stability.

Available in PDF, EPUB and Kindle. Book excerpt: Let the Water Do the Work is an important contribution to riparian restoration. By "thinking like a creek," one can harness the regenerative power of floods to reshape stream banks and rebuild floodplains along gullied stream channels. Induced Meandering is an artful blend of the natural sciences - geomorphology, hydrology and ecology - which govern channel forming processes. Induced Meandering directly challenges the dominant paradigm of river and creek stabilization by promoting the intentional erosion of selected banks while fostering deposition of eroded materials on an evolving floodplain. The river self-heals as the growth of native riparian vegetation accelerates the meandering process. Not all stream channel types are appropriate for Induced Meandering, yet the Induced Meandering philosophy of "going with the flow" can inform all stream restoration projects. Induced meandering strives to understand rivers as timeless entities governed by immutable rules serving their watersheds, setting their own timetables, and coping with their own realities as they carry mountains grain by grain to the sea. Anyone with an interest in natural resource management in these uncertain times should read this book and put these ideas to work.

Book excerpt: Since effective streambank protection measures are costly to install, a determined effort should be made to use vegetation because it is the most readily available material and is relatively inexpensive to obtain. Vegetation greatly reduces the hydraulic forces on the bank and provides other esthetic and environmental advantages over other methods of stabilization. This report describes a series of streambank vegetative studies located on the channels of Johnson, Goodwin and Peters Creek in Panola County near Batesville, Mississippi. On Johnson Creek, there are four sites; two of them use vegetation in conjunction with bank shaping and structural materials, the other two sites use vegetation in conjunction with structural devices without bank shaping. The site of Goodwin Creek uses vegetation in conjunction with bank shaping--with and without structural materials. The Peters Creek sites use woody vegetation in conjunction with structural devices without bank shaping. Criteria used in the design of the combined vegetative and structural projects are presented along with a detailed description of the project sites. Since these type studies require several years to evaluate, only preliminary results are presented and many of them are based on previous experience.

This book was released on 2015-03-01 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 500,000 bridges in the National Bridge Inventory (NBI) are built over streams. A large proportion of these bridges span alluvial streams that are continually adjusting their beds and banks. Many, especially those on more active streams, will experience problems with aggradation, degradation, bank erosion, and lateral channel shift during their useful life. The purpose of this document is to provide guidelines for identifying stream instability problems at highway stream crossings. Techniques for stream channel classification and reconnaissance, as well as rapid assessment methods for channel instability are summarized. Qualitative and quantitative geomorphic and engineering techniques useful in stream channel stability analysis are presented. This publication is an update of the third edition published in 2001. The HEC-20 manual covers geomorphic and hydraulic factors that affect stream stability and provides a step-by-step analysis procedure for evaluation of stream stability problems. Stream channel classification, stream reconnaissance techniques, and rapid assessment methods for channel stability are covered in detail. Quantitative techniques for channel stability analysis, including degradation analysis, are provided, and channel restoration concepts are introduced. Significant new material in this edition includes chapters on sediment transport concepts and channel stability in gravel bed streams, as well as expanded coverage of channel restoration concepts.
