Abstract:

This document provides guidelines for identifying stream instability problems at highway stream crossings. It is a dual unit update of the second edition published in 1995. 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 summarized. Quantitative techniques for channel stability analysis, including degradation analysis, are provided, and channel restoration concepts are introduced. In addition to minor editorial revisions, the following substantive changes have been made in this revised edition of HEC-20: corrected definition of density of water, ρ, (p. xi); revised definition of grain roughness ks, for gravel and coarse bed material (p. 6.15) and corrected multiplier for kinematic viscosity in Appendix A (Table A.7).
