Use of measured and interpolated cross- sections in hydraulic river modelling

چکیده
Recently, a benchmarking test study of several hydraulic river models has been undertaken by the authors ^. One of the tests being investigated was the performance of hydraulic river models in using measured and interpolated crosssections for unsteady flows. Details of the interpolation algorithm for obtaining interpolated cross-sections are described in the paper. It is shown that the appropriate use of the interpolated cross-sections can improve the performance and accuracy of hydraulic river models. Comparisons of results obtained by interpolating hydraulic parameters and interpolating geometric cross-sections have been made. It is demonstrated that the interpolation of cross-sections is superior to the interpolation of hydraulic parameters.

Some hydraulic characteristics of stream channels — depth, width, velocity, and suspended load — are measured quantitatively and vary with discharge as simple power functions at a given river cross section. Similar variations in relation to discharge exist among the cross sections along the length of a river under the condition that discharge at all points is equal in frequency of occurrence. T...

Introduction: As the main source of water and life for humans and other creatures, rivers may sometimes bring about destruction and irreparable damage. Therefore, it is necessary to study the hydraulic properties of the flow and the riverbed’s area to set a safe zone for human activities around it. On the other hand, constructions built along the river’s route such as bridges, weirs, superstruc...
