Abstract: Two methods of non-contact quick scan measuring river-bed topography were introduced. The topography under water was measured by the theory of ultrasonic echo wave and the topography upon water was measured by the theory of laser and CCD imaging. The testing system, the main problems in the test and the ways of solving them were presented.
