Diagrammet tar hänsyn till kornstorlek och vattnets flödeshastighet. Hjulströms diagram är ett diagram som inom hydrologin kan användas för att avgöra om sediment transporteras eroderas eller deponeras i strömmande vatten. The long profile changing processes.

It was originally published in his doctoral thesis studies of the morphological activity of rivers as illustrated by the river fyris.

Diagrammet tar hänsyn till kornstorlek och vattnets flödeshastighet. The vertical axis shows the average river velocity in cm per second cm s while the horizontal axis shows particle size in mm. Note that larger grains require higher flows in general. The upper line shows the erosional velocity or critical erosion velocity needed to initiate sediment erosion.
