In an effort to learn more about danxia topography, a study on the geomorphology of an area in China was conducted. Mount Danxia was the focus of the research, taking Digital Elevation Matrix (DEM) based data from many watersheds and basins in the area. Understanding the hydrology of the area can tell a lot about the nearby formations. For example, localized erosion has enhanced deepening of existing fractures rather than lateral erosion to form deep and narrow valleys, while long-term erosion provided large and gentle watersheds. This study used ArcGIS. These scientists took maps of the area and overlaid certain features they wanted to measure, such as stream length and size.
