Abstract

Cilj ovog istraživanja je predložiti mjere optimizacije postojećeg sustava odvodnje u dolini rijeke Neretve temeljem podataka o razinama vodostaja u glavnom i sabirnom kanalu poldera Vidrice. Podaci o vodostaju prikupljeni su putem automatskog monitoringa, dok su vrijednosti protoka u sabirnom kanalu dobivene hidrauličkim proračunom. Analizom vodostaja i provođenjem hidrauličkog proračuna utvrđeno je da neodržavanje sabirnog kanala dovodi do smanjenja protoka i protočne površine, što negativno utječe na hidrološki režim i smanjuje funkcionalnost samog kanala. Ključna mjera za optimizaciju sustava je rekonstrukcija sabirnog kanala, koja uključuje iskop (izmuljivanje) dna kanala i uklanjanje obrasle vegetacije. Osim toga, u radu se opisuju općenito površinski i podzemni sustavi odvodnje, te se detaljno opisuje postojeći sustav odvodnje u dolini rijeke Neretve.

Abstract (english)

The aim of this research is to suggest optimization measures for the existing drainage system in the Neretva River valley based on data regarding water levels in the primary and secondary channels of the Vidrice polder. Water level data was collected through automated monitoring, while flow values in the secondary channel were determined through hydraulic calculations. Through the analysis of water levels and the implementation of hydraulic calculations, it has been determined that the lack of maintenance of the secondary channel results in reduced flow and flow area, negatively affecting the hydrological regime and diminishing the functionality of the channel itself. The primary measure for system optimization is the reconstruction of the collecting channel, involving excavation (dredging) of the channel bottom and removal of overgrown vegetation. Additionally, this work provides a general overview of surface and subsurface drainage systems, along with a detailed description of the existing drainage system in the Neretva River valley.
