Abstract: The use of the specified time interval (STI) numerical schemes has been popular in applying the method of characteristics (MOC) to unsteady open‐channel flow problems. Studies and analyses of several variants of the STI ...

Abstract: Unsteady flows in movable‐bed open channels can be described by a set of three partial differential equations: the equations of continuity and motion for sediment‐laden flow and the equation of continuity for sediment. It ...

Abstract: For unsteady open‐channel flows having N interacting unknown variables, a system of

Abstract: The friction-slope term in the unsteady open-channel flow equations is examined using two numerical models based on different formulations of the governing equations and employing different solution methods. The purposes ...
