Abstract

~~Sufficient resolution of measured flow data under different hydraulic conditions is of prime importance to develop an understanding of river processes and to enable accurate numerical modelling. The objectives of this study were to obtain and assess a wide range of hydrometric and hydrodynamic data of the Red River in Winnipeg under varying flow conditions. Basic geometric parameters, water surface profile, dimensionless numbers (Froude, Reynolds, and entropy parameter), the stage-discharge rating curve, boundary friction through the use of three different coefficients, roughness height, and local and reach scale hydraulic shear stress were determined using the field data. An acoustic Doppler current profiler was used to collect spatial and temporal data along 10 km of the Red River between the South Perimeter Bridge and Fort Gary Bridge over a 2 year period.  High resolution water surface elevations at the reach extremes were also collected. These comprehensive results provide a better understanding and suitable knowledge for modeling of the complicated phenomenon occurring on the Red.
