Synopsis

Excerpt from A Combination Suspended-Load Sampler and Velocity Meter for Small Streams

In order to obtain the most accurate determinations of the suspended load and the average composition of the material, a stream should be sampled at a great many vertical and horizontal points in a cross section, the samples at each point to be taken during an interval long enough to eliminate the instantaneous. Variations often re?ected in clouds or boiling observable in heavily sediment-laden streams. For precise work, velocity measurements should also be made at the sampling points at frequent intervals to permit the rate of suspended load discharge to be calculated. It is possible, however, where lower degrees of accuracy will serve the immediate practical purpose, to simplify the procedure to the collection of only a few, or even one sample, with similar reductions in the number of velocity measure ments, or their omission at previously rated stations equipped with staff gage or stage recorders.
