The AA. aim to characterize rill network development from "point zero" in the artificially-created catchment "Hühnerwasser", located in the recultivation area of the open-cast lignite mine Welzow-South, near the city of Cottbus. To ensure unaffected development, the study was restricted to the analysis of remotely-sensed data. The AA. analyzed a series of photogrammetry-based digital elevation models (DEMs) for 10 points in time, over a period of 5 years and beginning with the initial state. The evolving erosion rill network was quantitatively described based on mapping from aerial photographs. DEMs and rill network maps were combined to specifically analyze the development of morphometry for different parts of the network and to characterize energy dissipation and connectivity. Results show an increasing similarity of overall statistical characteristics (e.g. drainage density) for 2 parts of the catchment, but a persistent influence of initial conditions on specific rill geometry. The AA. did not observe major influences of rill piracy and cross grading or a reduction of energy dissipation with network development
