- W2134488090 abstract "The entrainment and erosion of cohesive bed material, is partly controlled by the magnitude and distributionof positive and negative pore-water pressures. Upward-directed seepage forces within cohesive streambedsprovide a mechanism of entrainment for flocculated aggregates. In contrast, suction caused by negative pore-waterpressures is found to increase the shear strength of unsaturated cohesive bed and bank materials.A hypothesis for detachment and erosion of chips or blocks of cohesive bed material is proposed: (1) Large(5 m), rapid rises in stage increase pore pressures and decrease matric suction dramatically in the region justbelow the bed surface; (2) A relatively rapid decrease in stage causing a loss of downward water pressurecombined with low-rates of pore-pressure dissipation result in steepened hydraulic gradients just below the bedsurface; and (3) A resulting net upward seepage force is great enough to contribute to detachment andentrainment of cohesive bed material." @default.
