Experimental assignment of total drag coefficients of bodies embedded in a free surface stream.
The paper deals with an experimental determination of total drag coefficients of bodies of various shapes embedded in a free stream flow. The shapes of bodies were chosen by such way that they could model simple bridge constructions...
