  • Automatic Characterization of Boulders on Planetary Surfaces From High-Resolution Satellite Images 
    Prieur, Nils Charles; Amaro, Brian; Gonzalez, Emiliano; Kerner, Hannah; Medvedev, Sergei; Rubanenko, Lior; Werner, Stephanie C.; Xiao, Zhiyong; Zastrozhnov, Dmitry; Lapôtre, Mathieu G. A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Boulders form from a variety of geological processes, which their size, shape, and orientation may help us better understand. Furthermore, they represent potential hazards to spacecraft landing that need to be ...
  • Development of a 1D-2D coupled hydrodynamic model for the Øyeren Delta in southern Norway 
    Prieur, Nils Charles (Master thesis / Masteroppgave, 2011)
    In this study a coupled 1D-2D hydrodynamic model, MIKE FLOOD was used to simulate flood inundation extent, water levels and water velocities in the delta region of Lake Øyeren in southern Norway. The objective was to ...
  • The effect of target properties on transient crater scaling for simple craters 
    Prieur, Nils Charles; Rolf, Tobias; Luther, Robert; Wunnemann, Kai; Xiao, Zhiyong; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The effects of the coefficient of friction and porosity on impact cratering are not sufficiently considered in scaling laws that predict the crater size from a known impactor size, velocity, and mass. We carried out a ...
  • Formation of simple impact craters in layered targets: Implications for lunar crater morphology and regolith thickness 
    Prieur, Nils Charles; Rolf, Tobias; Wünnemann, Kai; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Impact crater morphologies vary significantly across the lunar maria. Craters with diameter less than 400 m are closely related to variations in target properties (rock strength, porosity, and layering) as well as the ...
  • Fragments Delivered by Secondary Craters at the Chang'E-4 Landing Site 
    Ding, Chunyu; Xiao, Zhiyong; Wu, Bo; Li, Yuan; Prieur, Nils Charles; Cai, Yuzhen; Su, Yan; Cui, Jun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The Chang'E‐4 landing site is depleted with boulders seen from both orbit and surface. However, the Yutu‐2 rover came across thousands of concreted fragments in and around an abnormally fresh crater that has more elevated ...
  • The self-secondary crater population of the Hokusai crater on Mercury 
    Xiao, Zhiyong; Prieur, Nils Charles; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Whether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique ...
