Abstract : Both model and prototype studies indicated that jetty fields are successful in alining rivers that carry appreciable amounts of suspended sediments. To compute the relative rate of sediment deposition, field data are required. The use of point data analysis, described in this report, aids greatly in extending field data and establishing river characteristic curves. To determine the design ischarge, it is recom mended that width and depth be plotted versus flow area and that a value be selected which corresponds to the flow area having the maximum scatter or deviation of data points with respect to depth and width. This is the lowest dis charge which will be difficult to control. The average river width corresponding to this dis charge should be used for the design channel width. The relative rate of deposition in a jetty field installation can be computed by trocedure demonstrated in this paper. However, future studies may indicate desirable modifica tions and refinements in the procedures. (Author)
