Flood Control Structures Research Program: Open-Channel Velocity Prediction Using STREMR Model.

Abstract

The STREMR two dimensional depth-averaged model is compared to observed data from three trapezoidal channel bends, one straight trapezoidal channel, and one natural channel bend having an erodible bed. STREMR was selected because it includes an empirical correction for secondary currents. Without the secondary correction activated, STREMR did poorly in channel bends. With the secondary correction activated, the model did well on the channel bottom and on the lower half of the side slope. Predicted velocities were greater than observed velocities on the upper half of the side slope. The secondary correction in natural channels is needed but less significant than in trapezoidal channels because natural channel bathymetry plays a significant role in defining velocity distribution.
