COMPUTATIONAL-REACH LENGTH FOR PRISMATIC CHANNELS. TECHNICAL NOTE

This note presents a methodology for the selection of reach length in unsteady, one-dimensional models of open channel flow. Using computational experiments, the authors determined an appropriate reach length for 425 combinations of channel and flow parameters. For each combination of parameters, they refined the finite difference grid until numerical error was reduced to 1.0% of a high resolution solution. They generated a set of dimensionless parameters and used regression analysis to relate channel and flood properties to an appropriate computational reach length.
