Sonaravna preureditev jezu na reki Reki : diplomska naloga

Gombač, Jure (author), Steinman, Franci (mentor)

Diplomska naloga obravnava probleme, ki j ih na vodotokih povzročajo predvsem manjši jezovi, ki nimajo izdelanih ustreznih ribjih prehodov. Ti povzročaj o predvsem fragmentacij o habitatov, preprečujejo migracijo vodnih organizmov ter spreminjajo lastnosti vode. V primeru višjega števila jezov na samem vodotoku, pa se takšni problemi še dodatno povečujejo. Zahteve Nature 2000 in zakonodaje, ki je naravnana k ohranjanju ter varovanju narave, spodbujajo oz. narekujejo izboljšanje degradiranih stanj. Na podlagi izbranih ciljev in pogojev oz. danosti v prostoru, je predstavljena rešitev v podobi prilagojenih pragov oz. drč, ki omogočajo prehod vodnih organizmov ter s tem vračaj o prejšnjo podobo vodotokov. Predvidena rešitev je zasnova na idejno/izvedbeni stopnji s potrebnimi izračuni in tehničnimi skicami. Primer je izdelan na podlagi delujočih izvedb v tujini, ki podobno prakso izvajajo že nekaj let, njihovi rezultati pa so se izkazali kot zelo uspešni.

• Title: Sustainable refurbishment of a weir on river Reka

Abstract

The thesis addresses the problems on rivers which are caused by lower dams that do not have established adequate fish ladders. These weirs cause fragmentation of habitats, prevent migration of aquatic organisms and alternate the properties of water bodies. The problems build up with higher number of dams. Natura 2000 and legislation that are aimed at preserving and protecting nature state and dictate improvement of degraded conditions. The solution is presented in form of boulder bar construction, which is based on the selected objectives and given conditions. These boulder bar construction enable migration of aquatic organisms and thus restoring the original conditions of the river. The solution is given in conceptual design/implementation stage with the necessary calculations and technical drawings. The example is based on operating implications from other countries in which such practice has shown to be very successful and with significant results.
