River restoration – riverine ecosystem improvement and protection measure

Abstract

Obnova vodotoka u Republici Hrvatskoj relativno je nova aktivnost vodnoga gospodarstva iako se u ostalim europskim zemljama provodi više od 30 godina. Obnovom vodotoka teži se ka prirodnijem stanju korita dok se istovremeno ostvaruju preduvjeti za povratom prirodnih procesa i funkcija vodotoka. Raspoložive mjere obnove vodotoka prilično variraju u opsegu i kompleksnosti stoga su u radu prikazane neke od najjednostavnijih pa do najopsežnijih vrsta zahvata. Prikazane mjere revitalizacije s opisom njihovog učinka kao i njihov utjecaj s hidrauličkog, hidrološkog, morfološkog, ekološkog i socio-ekonomskog aspekta. U radu je analizirano nekoliko projekata obnove vodotoka koji su provedeni ili su u fazi provedbe u Hrvatskoj i u zemljama Europske unije. Također je prikazan i načelni tijek provedbe projekata s mogućim dionicima.River restoration in Republic of Croatia is relatively new water management activity, even though it is conducted in other European countries for more than 30 years. River restoration aims toward more natural watercourse state, while at the same time fulfilling the preconditions for return of natural processes and watercourse functions. Available river restoration measures vary considerably in scope and complexity, therefore some of the simplest and most comprehensive types of interventions are presented in the thesis. Revitalization measures are presented describing their effect, as well as their hydraulic, hydrological, morphological, ecological and socio-economic aspects. This thesis analyses several river restoration projects that have been or are being implemented in Croatia and in European Union countries. It also outlines the principle of project implementation with potential stakeholders
