该报告介绍了美国93条河流的悬浮泥沙负荷和大约同时测量的河床负荷的现场数据。还包括相关的水力变量和（在可用的情况下）床上物质和泥沙负荷的粒度分析。这些数据是由不同的个人和组织测量的，其中许多数据迄今尚未公布。用标准方法测量悬浮载荷。除一个地点外，均用Helley-Smith采样器测量床质，通常在河流横截面上至少十个采样点。尽管存在众所周知的抽样问题，但在目前（1986年）的抽样能力阶段，这些数据可能是最好的。它们是第一个全面收集各种河流中实地测量的总泥沙负荷（河床负荷加上悬浮负荷）。
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.
