BS 3680-3D is an International Standard that discusses the methods of measurement of liquid flow in open channels.
BS 3680-3D specifies methods for measuring discharge in large rivers and estuaries by the moving-boat technique. BS 3680-3D provides examples of computation of a moving boat measurement.
BS 3680-3D covers the general requirements of the equipment.
BS 3680-4I on Moving-boat method is useful for:
The moving-boat technique uses a velocity-area method of determining discharge. The moving-boat measurement is made by traversing the stream along a preselected path that is generally normal to the streamflow.
BS 3680-3D provides you with the technicalities for a method called the moving boat method used to calculate the liquid flow in large rivers and estuaries. BS 3680-3D talks about the principle upon which the moving-boat method is based. BS 3680-3D gives you a description of the arrangement of the test instruments that are used to carry out the test method. This method described in BS 3680-3D helps the users to determine and measure the stream velocity in large rivers where it is comparatively difficult to measure the liquid flow.
BS 3680-3D is an effective step for measuring the liquid flow in open channels through the moving-boat method accurately.
