Topographic data reveal a buried fluvial landscape in the Simpson Desert, Australia

Formation of the highest sand dunes on Earth

“…7). We interpret this as representing the gently sloping surface of a former Distributive Fluvial System (DFS, Craddock et al, 2010;Weissmann et al, 2010) emanating from the southeast that was subsequently eroded into low rolling hills.…”

9.31 Dryland Fluvial Environments: Assessing Distinctiveness and Diversity from a Global Perspective

“…Remote sensing developments are enabling the detection and reconstruction of paleodrainage networks in more detail and over more extensive areas than has been possible previously, even in areas of widespread aeolian cover, thus providing context for interpretation of the development of the typically contracted, present-day drainage networks (e.g., Lancaster et al, 2000;Blumberg et al, 2004;Robinson et al, 2006;Stanley and Jorstad, 2006;Paillou et al, 2009;Craddock et al, 2010).

Computing water flow through complex landscapes – Part 1: Incorporating depressions in flow routing using FlowFill

“…In the latter case, flow routing is often recomputed over time to simulate the feedback between evolving topography and drainage patterns (Hobley et al, 2017;Tucker et al, 2011). Flow-routing calculations and drainage network construction also form the basis for topographic analysis algorithms to automatically pick channel heads (Clubb et al, 2014;Passalacqua et al, 2010;Pelletier, 2013), segment watersheds into representative hydrological units (Czuba and Foufoula-Georgiou, 2014;Ng et al, 2018;Teng et al, 2017), and link river-channel form with rates of tectonic uplift (Duvall et al, 2004;Perron and Royden, 2013;Willgoose et al, 1991) or subsidence (Paola et al, 1992;Wickert and Schildgen, 2019). These same tools have been applied to understand valley networks on Mars (Luo and Stepinski, 2009;Molloy and Stepinski, 2007), the impacts of freshwater forcing on climate during the most recent deglaciation (Ivanovic et al, 2017(Ivanovic et al, , 2018Riddick et al, 2018), and links between palaeo-drainage networks and modern economic and agri-cultural resources (Craddock et al, 2010).…”
