Abstract

Voda je važan prirodni resurs koji se koristi za potrebe poljoprivrede i industrije te predstavlja temeljni uvjet za život, ali i konstantan izvor opasnosti ukoliko se ne brinemo o njenoj kakvoći. U Republici Hrvatskoj se oko 90% potrebe za vodom namiruje zahvaćanjem podzemne vode stoga je važno poznavanje mehanizma obnavljanja zaliha podzemne vode koje bi mogle osigurati potrebe vodoopskrbe. U ovom diplomskom radu obrađeno je osječko vodocrpilište Vinogradi, najveće vodocrpilište u Republici Hrvatskoj u kojem se voda zahvaća iz pješčanih vodonosnika. Na crpilištu je u pogonu 18 zdenaca, generalnog smjera pružanja jugozapad-sjeveroistok, s pojedinačnom crpnom količinom od oko 40 l/s. Tijekom rada crpilišta uočeno je znatno sniženje specifične izdašnosti pa je donesena odluka o provedbi revitalizacije. Revitalizacija zdenca podrazumijeva sve postupke kojima je cilj poboljšanje hidrauličkih svojstava zdenca koja su narušena starenjem zdenca. U ovom radu obrađen je zdenac Z-6 kod kojeg se pristupilo revitalizaciji, a na temelju provedenog pokusnog crpljenja zdenca načinjena je interpretacija lokalnih parametara vodonosnika i parametara zdenca.

Abstract (english)

Water is an important natural resource that is used for agriculture and industry and is a fundamental condition for life, but also a constant source of danger if we do not care about its quality. Approximately 90% of Croatia's water requirements are met through groundwater catchment, so it is necessary to get to know the possibilities of renewal of groundwater reserves.This thesis elaborates the data on the well field Vinogradi near Osijek, the largest well field in Croatia, where the water is extracted from the sand aquifer. The water field has 18 functioning wells whose pumping gives a standardized water quantity of around 40 l/s. During the work of the well field, a significant decrease in specific yields was noted and decisions were made on the implementation of revitalization. Revitalization of the wells implies all the actions aimed at improving the hydraulic properties of the wells that are damaged by the aging of the wells. This thesis will take a special focus on the spare well Z – 6 and on the basis of the experimental pumping, the interpretation of the local hydraulic parameters of the aquifer and the parameters of the well.
