Fluvial disturbances, especially floods and droughts, are the main drivers of the successional patterns of riparian vegetation. Those disturbances control the riparian landscape dynamics through the direct interaction between flow and vegetation. The main aim of this work is to investigate the specific paths by which fluvial disturbances, distributed by its components of groundwater hydrology (...

Introduction: The Hypanis fan-shaped deposit in Xanthe Terra has been interpreted by many to be a late Noachian aged delta along the dichotomy boundary [15]. The putative delta was a compelling candidate landing site for the future Mars 2020 and ExoMars rover missions as it was positioned at the edge of an open basin, could have been an ideal environment for biosignature formation, concentratio...

This paper examines the commonly accepted assumption in the riparian literature that areas adjacent to streams do not burn. Using time-since-fire distributions, derived from stand-origin maps for a watershed in the front ranges of the Canadian Rocky Mountains, we found that the areas adjacent to streams and the whole study watershed have similar fire frequencies. In addition, the relative impor...

The paper presents an overview of recent publications on the fluvial suspended sediment flux to the Arctic Ocean. The total suspended matter exported from the Russian territory is 102×10 t/year and from the Canadian Arctic is 125×10 t/year. The total suspended matter (TSM) flux to the Arctic (227×10 t/year) is very low, only about 1% of the global flux. Mean concentrations of suspended matter a...

The movement of fluvial sediment shapes our rivers. Understanding sediment entrainment has been a goal of hydraulic engineers for almost a century1,2. Previous sediment entrainment models have been informed by laboratory experiments using grains that were free from biological material3. In natural river settings, however, sediments are invariably covered by bacteria, often forming visible biofi...

Morrowan-age units in the Permian Basin appear to show a “second-order” transgression from siliciclastic fluvial-deltaic to shallow-marine and subsequently to carbonate deposition. In general, Morrowan-age siliciclastics dominate deposition in the west of the Permian Basin, while carbonate deposition dominates in the east. The predominance of carbonate facies in the east is due to a lack of sil...

Detailed sedimentological analysis of a prodeltaic turbidite unit within the Pennsylvanian Minturn Formation provides insight into the nature of fan-delta deposition, and allows reconstruction of paleogeographic and paleoclimatic conditions within a tectonically active cratonic basin. The formation, a thick succession of fan-delta deposits, exhibits a complex stratigraphic architecture of alluv...

8 Adequate characterization of depositional architecture is of great importance when 9 studying fluvial outcrops as reservoir analogs. The complex three-dimensional (3D) 10 distribution and lateral/vertical relationships of sandstone bodies require a high degree of 11 stratigraphic control in order to make a proper assessment of the distribution and connectivity 12 of the reservoir facies. This...
