Kinematic Routing Method

Kinematic Routing can be used to model the hydraulics of upstream tributar­ies and secondary river branches, where the main concern is to route water to the main river system. The Kinematic Routing method does not facilitate the use of structures at Kinematic Routing branches. Moreover, the method does not account for backwater effects.

Since the Kinematic Routing method is unconditionally stable, it facilitates the use of large time steps, which is important when running the model in parallel with the hydrological model, MIKE SHE.

At Kinematic Routing branches, it is possible to run the model without infor­mation on cross-sections. In turn, this indicates that Kinematic Routing branches can not be used to model a looped part of a river network. Employ­ment of Kinematic Routing branches requires that all branches located upstream of a Kinematic Routing branch are defined in the same way.
