And in this case field experiment was conducted in order to measure the current velocity inside the drag-net made of thick-set twine. A summary of the results is shown below. (1) Current velocity measured at the inside of the net was 76-87% of that at the net mouth. The acceleration of current velocity, observable in the previous experiments, was not observed. (2) The ratio between the velocity at the inside of the net and that at the net mouth was expressed in the theoretical formula (showing Fig. 4).
