PCT No. PCT/EP90/00413 Sec. 371 Date Oct. 30, 1990 Sec. 102(e) Date Oct. 30, 1990 PCT Filed Mar. 14, 1990 PCT Pub. No. WO90/11517 PCT Pub. Date Oct. 4, 1990.A method and an apparatus for measuring materials of high viscosity floating on bodies of water are to provide a solution enabling a reliable monitoring of the water surface of standing and running bodies of water using simple means. This is achieved by means of the method in that the water surface of the body of water is excited by means of an oscillating device and in that the surface waves reflecting on the water surface are measured.
