The heavy rains in the winter of 2009-2010 in Spain activated all the sediment-feeder systems of a small reservoir built in the 1970s north of the Sierra de Almijara (province of Granada). The intensity of this activity has aided in recognizing a series of geomorphic features allowing the re-interpretation of previous data on the subsoil obtained from Ground Penetrating Radar (GPR) and sediment...
A detailed outcrop and sub-surface analysis was completed on the Peay Member sandstone (Frontier Formation) in the northeast Bighorn Basin, Wyoming, building on previous work by Clark (2010) and Hutsky (2011). Regional correlations reveal the sandstone body to be digitate in planform geometry, elongate along depositional dip, and restricted across depositional strike. It is interpreted to be th...
Restoration of sustainable geomorphic processes that create floodplain topography through development of sand-splay complexes at intentional breaches is one method to promote variability in physical structure needed for habitat restoration. The topography of splay complexes provides a range of floodplain elevations that creates local variability in (i) inundation duration and frequency and dept...
Abstract The Schrattenkalk Formation represents a complete succession of Lower Cretaceous shallow-water carbonate platform series cropping out in the Alpstein massif north-eastern Switzerland. is traditionally divided into two sedimentary units, “Lower” and “Upper” Schrattenkalk, separated by more marly Rawil Member. habitually dated to late Barremian, while Member are early Aptian. New field o...
Many coasts suffer from prevailing erosion, with them being particularly vulnerable to predicted climate change impacts, threatening coastal ecosystems, their services, infrastructures and populations. Understanding morpho-sedimentary dynamics is thus essential for management. However, vulnerability may differ locally, depending on exposure/protection local geological morpho-hydrodynamical feat...
