Hydrology

The annual medium flow of Doron of Beaufort was calculated over one 26 years period to Villard-on-Doron. It is assembled to 10,8 m ³ a second for a surface of basin of 244 km ². The river present of the seasonal fluctuations of flow typical of a nival mode, with high waters of spring-be due to the snow melt and carrying the average monthly flow on the level from 15 to 25 m ³ of at the end of April at July included (with an in June maximum), and a low water level of winter, November to March, involving a fall of the monthly medium flow until a minimum of 4,77 m ³ in January.

The VCN3 can fall until 2,49 m ³, in the event of dry period decennial, which remains extremely comfortable it is true. The VCN3 is the past minimal quantity or minimal flow over three days consecutive.

The flows of raw are unfortunately not available

The Lame of water past in the catchment area of the river is of 1 399 millimetres annually, which is very high and results from abundant precipitations on the Alps of north and, though completely normal in Savoy, even a record in the area constitutes. The specific flow (Qsp) is assembled thus at 44,3 liters a second and per square kilometer of basin.
