Abstract
A method is described for modelling the distribution of velocity acros s a river cross-section in a straight reach in uniform, steady flow. T he method uses a finite element model based on a simplified Navier-Sto kes equation and a mixing length hypothesis. The model is applied to a representative river reach and a comparison is made with velocity gau gings in the reach. Good agreement is shown where flow conditions matc h the assumptions on which the model is based.
