Abstract EN
Based on the results of the width of channel regulation on the field observations and indoor experiments, a new model of the width of channel regulation on hydraulic geometry relation was proposed and its coefficients were determined in theory in terms of the principle of dimensional analysis and multiple linear regression method in this paper.
Considering the action of channel width, average flow velocity, average water depth and the slope of bed river, the median grain size D50 was introduced.
Through field data were verified well, and flow gradient formulas and hydraulic formulas results were compared with more consistent ones, and it was shown that this model could better reflect relatively stable riverbed.
Moreover, the established expression not only was simple and explicit, but also better laid a good theoretical basis for waterway project design.
Last, taking the waterway regulation project which was from Shaoguan to Qingyuan for calculation, the results showed that new calculation method was feasible and it could be a useful reference for the design of waterway regulation.
