In hydrology, the head is the point on a watercourse up to which it has been artificially broadened and/or raised by an impoundment. Above the head of the reservoir natural conditions prevail; below it the water level above the riverbed has been raised by the impoundment and its flow rate reduced, unless and until banks, barrages, weir sluices or dams are overcome (overtopped), whereby a less frictional than natural course will exist (mid-level and surface rather than bed and bank currents) resulting in flash flooding below.

rdfs:comment	Als Stauwurzel bezeichnet man den Punkt eines Fließgewässers, bis zu dem sich eine künstliche Veränderung des Flusses durch Aufstau auswirkt. Oberhalb der Stauwurzel herrschen natürliche Verhältnisse, unterhalb der Stauwurzel ist durch den Stau der Wasserstand über der Gewässersohle erhöht und die Fließgeschwindigkeit herabgesetzt. Grundsätzlich ist zwischen einer Stauwurzel am Hauptzufluss einer Talsperre und einer Stauwurzel an einem gestauten Fluss (Staustufe, Stauhaltung) zu unterscheiden.

In principle, a distinction must be drawn between the head of a reservoir impounded by a dam, and the head of a works resulting from a barrage or canal locks. (en)
