Suspended in water colum (weak flow bedload sediment moving close to bed (channel bottom higher flow conditions) Capacity volume of sediment a river can carry (increases as discharge and velocity. 3. a: be able to define suspended load and bedload. What factors controls whether sediment will be transported by suspended versus bedload? a. conditions) b. 6. a. b. c: the mississippi river has changed the location where it discharges sediment to the gulf of.
