Derivations of the general form of fluvial resistance and sediment load relations are presented. The relations are sufficiently general to encompass the various specific dimensionally homogeneous relations that appear in the literature. An outline of the number and type of constraints necessary to specify solution sets for problems in equilibrium flow is presented. It is shown that any pair of resistance and load relations uniquely specifies depth-discharge and sediment transport rating curves at given slopes and bed particle Reynolds numbers. Such a format allows for direct graphical calculation of such parameters as slope, discharge, load, etc., from appropriate input information. Several examples of load and resistance relations presented in the generalized format are analyzed.
