| Abstract: | Terrain medelling is a common task for an engineer engaged in the field of river engineering. In the past three decades, a number of methods for terrain modelling haVe been proposed in surveying, civil engineering and in other fields. However, workers in different fields do not wish to achieve the same objectives. In river engineering, the data features and data collection methods are different from those in other fields. Therefore, a selection of suitable methods for terrain modelling that match the data features to obtain accurate terrain models is of importance. This paper deals with the methods for terrain modelling in river engineering. Attempts are made to summarize the methods. The problems and suitability of the methods associated with river engineering are discussed. Finally. some suggestions as to the selection of the terrain modelling methods are presented. |
