Mechanisms governing avulsions in transient landscapes : analysis of the May 2006 Suncook River avulsion in Epsom, New Hampshire
Avulsions, or rapid changes in the location of a river, usually occur in environments such as deltas, floodplains, and alluvial fans where net-deposition can raise the bed of the river above its floodplain. Avulsions are less frequent in transient landscapes, such as New England, where topography …

Sediment wave-induced channel evolution following the 2006 avulsion of the Suncook River in Epsom, New Hampshire
… increasing the elevation of the bed and driving avulsions. The purpose of this study is to model the evolution of a sediment wave in the Suncook River in order to understand how it can increase the risk of floods and avulsions in the system over time. We developed a mathematical model using the …

Paleosol evolution in a sequence stratigraphic framework, Cretaceous Ferron Notom Delta, south central Utah, U.S.A.
… to < 500 years), possibly reflecting short-term avulsions. Fluvial aggradational cycle sets in the succession are aggregates of fluvial aggradational cycles, bounded by relatively mature paleosols or erosionally top-truncation. They represent multiple small-scale depositional events that span not …

Late Quaternary Mississippi River Incised Valley Fill: Transgressive Depositional Packages
… Attenuated rates of sea level rise and periodic avulsions led to development and subsequent abandonment of several shelf phase deltas and barrier island arcs as well as gradual encroachment of the top stratum up the alluvial valley as aggradational depositon filled available accommodation …

Remote sensing of river kinematics and their expression in the modern and ancient stratigraphic record
… of perturbations (bend cutoffs and channel avulsions) on the large-scale kinematics of rivers; (2) the role of flood event-scale discharge variability on fine-scale patterns of erosion, deposition, and preservation along channel banklines; and (3) the three-dimensional nature of fluvial …

Role of Froude supercritical flow in active margin basin-floor fans, The
… of the submarine fan occurred through channel avulsions rather than bifurcations into distributary channels. Juncal formation demonstrates proximal to distal submarine fan environments. The study shows that supercritical flow structures occur at multiple scales and occur across the whole fan. …

The biomechanics of bruising
… of physical injuries such as abrasions, avulsions and bruising can prove to be vital pieces of evidence. Bruising is the most common of these injuries, yet there is a lack of understanding of the parameters required for their formation. Furthermore there is little agreement on a standard …

River bifurcations: key processes, timescales and evolutionary trajectories
River bifurcations are constituent components of multi-thread fluvial systems, playing a crucial role in their morphodynamic evolution. As highlighted by several field studies and laboratory investigations, natural bifurcations tend to display unbalanced configurations, in which one branch carries …
