Full Equations Utilities (FEQUTL) Model for the Approximation of Hydraulic Characteristics of Open Channels and Control Structures During Unsteady Flow
The hydraulic characteristics of open channels are divided between the description of the shape, size, and frictional resistance effects associated with the channel boundaries and the losses associated with abrupt expansions and contractions. Short channels, which allow high flows to bypass hydraulic structures in the stream, such as bridges and culverts, pose special problems that are discussed in this section. The description of the shape, size, and frictional resistance effects of channel boundaries are basic concepts and considered first in this section.
