Measurement of liquid flow in open channels - Methods for measurement of suspended sediment
Specifies methods for detailed measurement of sediment concentration and also methods for routine sampling. Because sediment load is highly variable with stage and is also highly variable at the same stage in different floods, and because the bulk of sediment is carried in flood periods, accurate computation of total sediment flow in a period entails routine sampling at normal flows combined with frequent routine sampling on rise, peak and fall in floods.
