چکیده مقاله
A typical problem in computational hydraulics is to transfer information i e , pressure and velocity field from one river cross section to another In hydraulic routing, the governing equations can be considered to be a combination of continuity and momentum equations for which its numerical solution requires a huge amount of data, e g , river longitudinal and lateral cross sections Unfortunately, these data are lacking in practical situations and their preparation calls for extensive human and financial resources Furthermore, these valuable data are subjected to variation due to erosion and sedimentation processes The basic question is to see if Saint Venant equations can be simplified to a form which does not require river cross section In the current literature, it is argued that diffusion wave has this characteristic In light of this, it is further claimed that parameter s incorporated into Saint Venant equations are of local and distributed nature while that of diffusion wave are of global and lumped characteristic Thus, the purpose of the current paper is to explore the extent to which this claim is valid Upon its validation, the diffusion wave routing can be effectively utilized to transfer the stage/discharge hydrographs to the required section
