内容記述 | Three topographical parameters, drainage area. exterior links and valley depth, are calculated as the criteria to define stream heads on digital elevation models in this study. Their variations effect on Horton-Strahler ordered stream numbers and length. Three topographical parameters are classified into two types. "Successive" and "non-successive" parameter is determined by whether it increases successively from upstream or not. The differences between two parameters cause whether stream numbers decrements and length increments associated with threshold increments have fluctuations or not. Moreover, order transition styles of successive parameters are singledirectional, such as lower order to higher order stream, and those of non-successive parameters are bi-directional. This indicates that Horton-Strahler ordered streams are largely influenced by the threshold parameters. | |||||
