Stream Load Classifications. Bed load. : Sediments moving predominantly in contact with or close to the stream bed.. Suspended load. : Sediments that move primarily suspended in fluid flow but may interact with bed load and is comprised primarily of silts and clays and sometimes sand. Suspended load has a continual exchange between sediment in fluid flow and on the bed as it is constantly being entrained from the bed and suspended while heavier particles settle out from the flow to the bed. .
