Introduction
localized erosion or aggradation of sediment in specific locations can be quickly remedied and the problem
will go away. Before this assumption can be made, it is wise to consider the impact on the entire system
through comprehensive evaluation and analysis. This manual will provide general guidance for system-wide
channel rehabilitation by introducing basic fundamentals of geomorphology and channel processes, along
with fundamental engineering design methods for performing background evaluations, conducting field data
investigations, evaluating channel stability, and producing stable channel designs.
1.2
SCOPE
Considerable information has been published on methods to stabilize channels and banks. The
intent of this manual is to provide a systematic basin-wide approach to channel rehabilitation, with emphasis
on the basic information and procedures needed to perform an analysis and preliminary design of the
channel rehabilitation project. Specific alternative designs for structures, and bank stabilization techniques
are not presented. References are provided in the text to give the reader a source of information for
detailed design. The project design process presented herein represents an attempt to provide the user with
guidance for addressing the impacts of channel modification projects.
