  Text part about channel normalisation: Would be good to refer to box 3.

  Suggest more on smaller barriers. Recent UK research identified only 97% of the river network in UK is fragmented and <1% of catchments are free of articicial barriers. https://amber.international/wp-content/uploads/2019/04/Jones_etal_2019.pdf

  Dikes, dams etc are "hydromorphological pressures" according to a glossary now being developed by CIS experts on hydromorphology.

  "Hydromorphological alterations" are alterations in the hydromorphological conditions which are caused by physical modification(s). Therefore, a dam is the pressure and hydromorphological alteration would be e.g. disruption of continuity, flow changes etc.
  

  Therefore, I suggest that you replace the term alterations in the Box with pressures.

  Box 2, Dikes and Tisza river example: Tisza River shows that same discharge values have ascendant water levels (the same amount of discharge flows at higher water levels). This is due to floodplain sedimentation. Narrow active floodplains on lowland are the recipient of sediment since more than 170 years.

  Dams: downstream stretches of the dams, a lack of sediment can occur, which can lead to deepening of the riverbed, floodplain cut off and lowering of the groundwater level.
