Abstract:

A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and extend below the potential channel-bed scour. The computer model simulates sediment transport and associated river channel changes which, in a curved reach, is also affected by the spiral motion or secondary currents. The bank protection for the Rillito River was designed based upon the simulated pattern of channel-bed scour. Variable toe elevations for the banks were used to provide an effective protection.
