Measurement of liquid flow in open channels - Measuring instruments and equipment - Calibration of rotating-element current-meters in straight open tanks
Specifies methods for measuring discharge in large rivers and estuaries by the moving-boat technique. In the following sections procedures applicable to this method and the general requirements of equipment are covered. A complete facsimile example of computation of a moving boat measurement is given in the annexes.

Liquid flow measurement in open channels by weirs and flumes — Triangular profile weirs
Liquid flow measurement in open channels — Vocabulary and symbols
Liquid flow measurement in open channels by weirs and flumes — Free overfall weirs of finite crest width (rectangular broad-crested weirs)
Deals with different types of suspended sediment load samplers. These samplers are classified according to their mode of operation into two general types: "instanteneous" and "time-integrating". The "time-integrating" samplers may be again divided into "point-integrating" samplers and "depth-integrating" samplers.
Liquid flow measurement in open channels; Functional requirements and characteristics of suspended sediment load samplers
Specifies a method for the estimation of sub-critical flow of clear water in smooth, straight, rectangular prismatic open channels with a vertical drop and discharging freely. Using the measured depth at the end, the flow in rectangular channels (horizontal or sloping) with confined nappe and unconfined nappe may be estimated.
Liquid flow measurement in open channels by weirs and flumes; End-depth method for estimation of flow in rectangular channels with a free overfall
Specifies the procedure to be used for the calibration of current-meters, i.e. for the experimental determination of the relationship between liquid velocity and rate of revolution of the rotating element. Specifies also the type of tank and equipment to be used and the method of presenting the results.
