4. DESCRIPTION OF THE CHANNEL GEOMETRY
Channel geometry--the description of the size and shape of the channels in which water flows--is often given cursory treatment in modeling documentation although it forms the foundation of any analysis of open-channel hydraulics. The description of the hydraulic geometry should be consistent with the demands of the analysis and the requirements of the governing equations. Use of 1-D flow equations is assumed throughout the analysis; therefore, an extensive review of implications for the description of the channel geometry is of great benefit.
