This study includes an investigation of analytical models for the description of flow and bed charactersitics in a bend of the Sacramento River, California; and a study of a proposed new technique for bank protection. Existing models for the prediction of the steady-state transverse bed profile in channel bends are reviewed; and alternative models are developed and validated. The new models predict the transverse bed slope to-vary linearly with d/r (the ratio of depth, d, to radius curvature, r) and almost linearly with the sediment-particle Froude number. Equations for the transverse variation of depth-averaged' velocity and mean-grain size also are developed, which, together with the equations for the transverse variation of depth, can provide a guide to the depth of bed erosion and depth-averaged velocity near the outer bank of river bends. It is shown, theoretically and by a physical model, that short, vertical, submerged vanes installed at incidence to the channel axis in the outer banks of a river-bend channel significantly reduce the secondary currents and the attendant undermining and high-velocity attack of the outer bank. The effect of the vanes on the secondary flow is estimated by a simple torque calculation using the. Kutta-Joukowski theorem. A design relation for the van spacing is derived by equating the torque, about the channel centroid, produced by the flow curvature to that resulting from the lateral force exerted on the vanes. The relation is verified in an idealized, physical model of the mentioned bend of the Sacramento River, Calif.

This report describes a series of experiments that were performed in a laboratory flume that was adapted to allow computer control of the independent experimental variables, and computer acquisition of data during experiments. The object of the study was to relate the Darcy-Weisbach resistance coefficient of an alluvial channel flow to the bed roughness as expressed by the standard deviation of bed elevation records (a measure of the dune and antidune roughness height). Since the Darcy-Weisbach coefficient in an alluvial channel shows considerable time variation even in supposedly steady uniform flows, and since the bed roughness, as measured from the time records of the bed elevation, is a stochastic quantity; time records of the Darcy-Weisbach coefficient and of the bed elevation were analyzed to obtain probability density functions, which were typified by means values and standard deviations of the relevant quantities. Autocorrelation functions of the time records were also computed and plotted. From these functions, time constants for variation of the resistance coefficient and for the propagation of bed forms were obtained. The Darcy-Weisbach resistance coefficient is of importance in the development of mathematical models of streamflow for predicting floodwave propagation, channel bed and bank modification, and the intensity of fluvial attack on channel protection or river training structures.
