Becva
Key features of the case study
Site description
The restoration project in the Czech Republic, investigated in REFORM as a case-study and coded as CZ_R1, is situated at the Becva River (Danube water basin) near the village Osek nad Becvou. At this point the upper catchment measures about 1532 km². The mean discharge near the site is 16.6 m³/s. In this section the Becva River is a 7th order stream and is assigned to the fish region Epipotamal.
Measures selection
The restored reach is one of five river stretches which were passively renaturalized by floods in 1997. In comparison with still regulated channels the 450 m long restored section is characterized by intensive erosional and depositional processes. Wider channel and intermittent occurrence of large woody debris in channel contribute to the development of hydromorphological features characteristic of braiding channel. Higher heterogeneity of river habitats was documented in terms of water chemistry, water temperature, substrate and aquatic biota.
