Hydrology

At the confluence of the Thalbach in the Ill , the mean flow rate (MQ) is 0.54 m³ / s; the catchment area here covers 78.4 km².

At the Wittersdorf gauge , the average annual runoff of the Thalbach was calculated over a period of 31 years (1980–2010) . The catchment area at this point, at 70 km², corresponds to around 89.3% of the entire catchment area of ​​the river.

The flow rate fluctuates quite strongly over the course of the year. The highest water levels are measured between December and May. The flow rate reached its peak in December at 0.96 m³ / s. From June onwards the discharge drops sharply and reaches its lowest level in August with 0.18 m³ / s, after which it increases again from month to month.

The monthly mean discharge (MQ) of the Thalbach in m³ / s, measured at the Wittersdorf hydrological station.
