Feedbacks between erosion and sediment transport in experimental bedrock channels
Natural bedrock rivers flow in self-formed channels and form diverse erosional morphologies. The parameters that collectively define channel morphology (e.g. width, slope, bed roughness, bedrock exposure, sediment size distribution) all influence river incision rates and dynamically adjust in poorly understood ways to imposed fluid and sediment fluxes. To explore the mechanics of river incision...
متن کاملWeathering and erosion of fractured bedrock systems
We explore the contribution of fractures (joints) in controlling the rate of weathering advance for a low-porosity rock by using methods of homogenization to create averaged weathering equations. The rate of advance of the weathering front can be expressed as the same rate observed in non-fractured media (or in an individual block) divided by the volume fraction of nonfractured blocks in the fr...
متن کاملExperimental study of bedrock erosion by granular flows*
[1] Field studies suggest that bedrock incision by granular flows may be the primary process cutting valleys in steep, unglaciated landscapes. An expression has been proposed for debris flow incision into bedrock which posits that erosion rate depends on stresses due to granular interactions at the snout of debris flows. Here, we explore this idea by conducting laboratory experiments to test th...
متن کاملAmplified erosion above waterfalls and oversteepened bedrock reaches
, where E(x=La) is the erosion rate at the upstream end of the flow acceleration zone above a waterfall, Fr is the Froude number at this setting, and n ranges between 0.5–1.7. This amplification expression suggests that erosion at the lip could be as much as 2–5 times higher relative to erosion at a normal setting with identical hydraulic geometry. Utilizing this erosion amplification expressio...
متن کاملAn Assessment of Wind Erosion Schemes in Dust Emission Simulations over the Middle East
Extended abstract 1- INTRODUCTION Atmospheric aerosols, solid and liquid particles in the atmosphere, play a crucial role in the atmospheric radiation equilibrium. These particles have an influence on the scattering and absorption of short wavelength radiation, and on the other hand, affect radiation absorption and emission in long wavelengths. Dust particles are among the importan...
