Description :
The suitability of 5 sediment transport capacity functions was evaluated for overland flow conditions using graphical and statistical analysis. The results show that the application of these functions is limited to the range of hydraulic and sediment conditions for which each was formulated. To improve predictions of transport capacity under overland flow conditions, especially at low flow intensities, a new function, based on the unit stream power concept, was derived using experimental data.
