Abstract
We investigate experimentally the changes of drainage structures on triangulated terrains when noise is applied. Given real world data sets, we examine two techniques for identifying watersheds on terrains created using the same data set yet under multiple noise instances. For the needs of our experiments we have developed a robust implementation of an algorithm that computes drainage structures on triangulated terrains under the assumption that water always follows the direction of steepest descent. We provide here also a description of our implementation which is based on CGAL.
