Q. Define the Moving boat method?

Moving boat method has been more recently evolved and tested in the U.S.A. and holds promise in measurement of discharge of big rivers and tidal waterways. If a current meter is towed by means of a boat in the same direction as the current, the velocity measured by the current meter will be the sum of boat velocity and-the current velocity. If the current meter is towed in the direction opposite the current, velocity measured by the current meter will be the difference between the boat and the current velocities. By moving boat parallel to flow at various distance from the bank, velocity of flow across the section can thus be computed. This is the underlying principle of moving boat method. Since the whole operation takes relatively short time, the method is convenient for adoption in case of big rivers and tidal waterways. Further details of the methods are available in literature.
