Accelerating Dense-Water Flow down a Slope [PDF]
Journal of Physical Oceanography, 2009 Abstract Where water is denser on a shallow shelf than in the adjacent deep ocean, it tends to flow down the slope from shelf to ocean. The flow can be in a steady bottom boundary layer for moderate combinations of upslope density gradient −ρx∞ and bottom slope (angle θ to horizontal):Here g is acceleration due to gravity, ρ0 is a mean ...

Rigid vegetation affects slope flow velocity
WaterAbstract The mean slope flow velocity is critical in soil erosion models but the mechanism of its variation under rigid vegetation cover remains unclear. On natural slopes, vegetation grows predominantly perpendicular to the horizontal plane (BH), with some growing perpendicularly to the slope surface (BS); however, current research often ...

Estimating flow resistance in steep slope rills [PDF]
, 2021 Recent research recognized that the slope of 18% can be used to distinguish between the ‘gentle slope’ case and that of ‘steep slope’ for the detected differences in hydraulic variables (flow depth, velocity, Reynolds number, Froude number) and those ...

Towards a better understanding of debris flow sediment sources: Monitoring of an active rock slope at Spitze Stei, Switzerland [PDF]
, 2023 Rapid process cascades can lead to destructive debris flows. Identifying and characterizing the processes conditioning debris-flow occurrence will strongly contribute to the mitigation of debris-flow hazards.

A study of the debris flow activity on the one-stepped channel slope
Soil and Water Research, 2015 The purpose of this study is to evaluate the behaviour and mechanism of debris flow on various slopes through numerical simulation. The numerical simulation was performed using the Finite Difference Element Method based on the equation of mass ...

Study on Erosion Process Characteristics of Frozen Soil Slope in Loess Hilly Region
Shuitu baochi yanjiu, 2022 In order to explore the differences in erosion between unfrozen slope and frozen slope under different runoff slope lengths in the Loess Hilly Region, simulated freezing and water discharge scouring tests were carried out indoors.
