Geometry of cross-sections on the selected river reaches (a) RR2, (b) RR3, (c) RR4, (d) RR8, (e) RR11 on the Belá River where river training were carried out. The blue cross-section represents the reference state (PRE) of the river before the flood in July 2018; the red cross-section represents the state after this flood event and river training during August 2018 (POST). At each cross-section, the width of the main channel (m) is marked (red and blue numbers). Bankfull stage at each cross-section reflects measured bankfull width where value ± 2018 points out differences in width between pre- and post-flood management periods. The direction of the arrows marked in cross-sections represents surface modification of the river’s active zone during river training.
