  • Summary

    Relationships relating channel width, depth, and cross-section as well as discharge to drainage basin area are regional relationships, because they are developed at the basin scale. These relationships constitute regional hydraulic geometry, which is utilized in stream assessments, evaluating channel characteristics, identifying field indicators of bankfull discharge, and delineation of regional boundaries, hydrologic regions, and ecoregions. This chapter presents these regional relationships.

  • Summary

    Hydraulic geometry is a quantitative description of the variation of river characteristics with variation in discharge and sediment load. It is impacted by climate, geology, and human interference. Hydraulic geometry relations have been expressed in power form and have been derived using a multitude of hypotheses. These relations play a fundamental role in the design of alluvial canals, river training works, and watershed management. The objective of this chapter is to introduce preliminary concepts that are deemed important for understanding different aspects of hydraulic geometry.
