[1] Field data from channels in the Henry Mountains of Utah demonstrate that abundant coarse sediment can inhibit fluvial incision into bedrock by armoring channel beds (the cover effect). We compare several small channels that share tributary junctions and have incised into the same sedimentary bedrock unit (Navajo Sandstone) but contain differing amounts of coarse diorite clasts owing to the ...

in the current study, the generalized maximum entropy (gme) and dynamic positive equilibrium problem (dpep) approach were introduced and used to estimate the set of dynamic supply functions of selected annual crops in mashhad-chenaran plain during the years 2003-2011.in addition, the allen and morishima elasticities of derived demand inputs, and supply elasticity of the crops were determined. t...

[1] Independent lithologic and structural controls in fluvial bedrock systems interact with coarse sediment transport processes to play a key role in bedrock incision processes such as abrasion. During a 3 year study on the Ocoee River in the Blue Ridge Province of the southern Appalachians, USA, we used painted tracer clasts to measure coarse sediment transport dynamics and address whether dif...
