Liquid flow measurement in open channels; Slope-area method
Описание (англ.):
Specifies the method of determining the slope and area of cross-section of the stream, and of computing the discharge therefrom. The method provides an approximate estimate of the discharge in somewhat special conditions in the stream. It can be used with some degree of accuracy in channels with stable bounderies such as rock (or very cohesive clay) bed and sides, and in channels with relatively coarse bed material.
