Abstract

Longitudinal connectivity represent the way in which organisms move the energy and material exchanges located throughout the water. Fragmentation the longitudinal connectivity of watercourses  caused by dams or other hydrotechnical constructions represent a major impact on sediment transport, hydrological regime, downstream moving and biota migration. The hydromorphological elements (river continuity), as well as chemical, biological, physicochemical elements characterize the ecological status of  rivers.Migratory fish species: nase (Chondrostoma nasus - protected by Bern Convention - Appendix III) and barbel (Barbus barbus - rare species, protected Habitats Directive (Annex V), annex 4A of Low nr.462 and Red List of RBDD) are blocked but the Hydrotechnical constructions (discharge sills, dams etc) located across the watercourse Somes Mic River. One of the important think of this system is the  gravitational fall of water. This solution  will lead to the restoration of the longitudinal connection of the Someşul Mic River in the Manastur neighborhood. România is part of the European Union and it has the obligation to implement the provisions of the Water Framework Directive 2000/60/EC, transposed into Romanian legislation by the Water Law 107/1996 as supplemented and amended (Act 310/2004). This  engineering solution for fish fauna migration upstream – downstream of the spillways  supports  the Water Framework Directive 2000/60/EC, transposed into Romanian legislation by the Water Law 107/1996 as supplemented and amended (Act 310/2004).

Keywords: fish migration, Someşul Mic River, longitudinal connectivity, spillways, lotic ecosystem
