| Abstract: | The calculation of the correction data of the scaling time delay of the echometer was stated.The geomorphologic map was drawn respectively by the scaling time delay of SDH-13D and SDH-13A echometer in order to measure a underwater geomorphy.And the comparison of the contour trend and the cross section data before and after the correction was made. |
