This paper presents the results of an extensive research into model test technique and the extrapolation problem in shallow water. These results enable us to examine the necessity for the use. of a method of three-dimensional extrapolation for shallow water. Experimental data on wall effect have been obtained by carrying out tests according to the method of images in a pressure-tight shallow-water basin. With the aid of a three-dimensional extrapolator the wall effect has been divided into effects on frictional and on wave-making model resistance. The results of the wall-effect tests were compared with the Kreitner theory and the influence of slots between tank walls and an adjustable bottom was analyzed. The results of propulsion and overload tests are given. Finally the correlation between model tests in shallow water and full-scale trials on a lake and the river Rhine has been discussed.
