Code N09 Sector Hydro Morphology The complete description of the NWRM n9_-_removal_of_dams_and_other_longitudinal_barriers.pdf Summary Dams and other transversal barriers are obstacles crossing the river section and causing discontinuities for sediment and fauna. Removing them consists in destroying all the obstacles, restoring the slope and the longitudinal profile of the river, therefore allowing re-establishment of fluvial dynamics, as well as sedimentary and ecological continuity.
