Our transcription: Although considerable amounts of sediment are transported as bed load, most of a stream's sediment is typically carried in suspension and in solution.
"Suspended load" includes material like silts or clays -- it is light enough to be swept along in the current without touching bottom.
"Dissolved load" is invisible -- it is the ever-present soluble material which results from chemical weathering of the rocks along the channel.
