Liquid flow measurement in open channels; Methods for measurement of suspended sediment
Описание (англ.):
Gives 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 floods, accurate computation of total sediment flow in a period entails routine sampling at normal flows combined with frequentroutine sampling on rise, fall and peak in floods.
