Total Bed-Material Transport

A method of estimating the bed-material discharge of sand-bed flumes, canals, and rivers is presented. The method uses a group of curves developed from flume data that relate intensity of transport, intensity of shear, and the median fall diameter of the bed material. Also, these curves illustrate that the intensity of transport varies with regime of flow and form of bed roughness. Application of the method yields good results for sand-bed channels when the depth of flow is less than 4 ft.
