Anticipating the potential for and recognizing the existence of channel instabilities is a critical aspect of locating and designing highways in river environments. Channel instabilities include oscillations in channel-bed elevation, variations in river orientation and location, and major river migrations or meanders. Factors affecting river stability have been classified as natural or accelerated. Natural instabilities result from changes in hydrometerology whereas accelerated erosion is usually a result of man's activiites within the watershed. Identifying channel instabilities requires an understanding of the geomorphic processes occurring within the watershed in question and an awareness of all activities that affect it. A thorough analysis of the stability of the river system should include consideration of past changes in the system and changes in progress, as well as a geomorphic analysis to predict future changes.
