The report presents field data of suspended-sediment loads and approximately concurrently measured bedloads for 93 United States streams.Also included are the associated hydraulic variables and (where available) the particle-size analyses of the bed material and sediment loads.The data, many of which have not been published heretofore, were measured by various individuals and organizations.Suspended loads were measured with standard methods.Bedloads, except for one site, were measured with the Helley-Smith sampler, generally at a minimum of ten sampling points over the stream cross section.In spite of the well-known sampling problems, the data probably are the best available at the present (1986) stage of sampling capability.They are the first comprehensive collection of field-measured total sediment loads (bedloads plus suspended loads) in a variety of streams.
