Quantifying Hydraulic Geometry and Whitewater Coverage for Steep Proglacial Streams to Support Process-Based Stream Temperature Modelling.

At-a-station hydraulic geometry (AASHG) relationships describe the dependence of a river's width, mean depth and mean velocity on discharge at a given location, and are typically modelled as power-law functions. They are often used when modelling stream temperature under unsteady flow conditions. Deriving AASHG relationships is challenging for steep proglacial streams due to the combination of complex morphology and velocity distributions, and rapidly varying flow.

Sediment Transport Assessment for Rio Gualaxo Do Norte After the Fundão Dam Failure.

The debris flood created by the 5 November 2015 failure of the Fundão dam in Brazil injected a large amount of fine sediment in the Gualaxo do Norte River system. Although coarse and sand-sized sediment injections in rivers have been studied in relative detail, little is known about river response to overloading of mud-sized sediments (consisting of clay and silt). This paper presents an assessment of suspended sediment transport occurring in and along the Gualaxo do Norte River after the Fundão dam failure to contribute to the general understanding of how rivers recover following large inputs of mud-sized sediments (consisting of clay and silt).
