Abstract

Krško područje sadržava zalihe podzemne vode vrlo visoke kakvoće i neprocjenjive vrijednosti. Zbog svojih značajki krško je područje izuzetno podložno antropogenim utjecajima, što ga čini iznimno ranjivim. Sliv izvora Jadra i Žrnovnice jedan je od najznačajnijih izvora krškog područja u Hrvatskoj te je jedan od najvećih slivova u kršu Dinarida. Izvori Jadro i Žrnovnica opskrbljuju pitkom vodom gotovo cijelu Splitsko-dalmatinsku županiju. U ovom diplomskom radu opisan je postupak analize prirodne ranjivosti navedenog sliva u svrhu zaštite podzemnih voda. Za procjenu ranjivosti korištena je KAVA metoda. Ona je modificirana na osnovu postojećih metoda za procjenu prirodne ranjivosti te je razvijena i testirana u skladu sa svim karakteristikama dubokih krških vodonosnika u području Dinarida. Konačna procjena prirodne ranjivosti prema navedenoj metodi (u ovom slučaju analiza ranjivosti lokacija krških izvora) izrađuje se u potpunosti pomoću GIS tehnologije. KAVA metoda u analizi prirodne ranjivosti koristi četiri specifična faktora: O - faktor (pokrovne naslage), P – faktor (utjecaj oborina), I – faktor (utjecaj infiltracije) i A – faktor (uvjeti vodonosnika). Dobiveni rezultati omogućuju izradu konačne karte ranjivosti izvora (Source Vulnerability Index - SVI). Na temelju konačnog rezultata procjene prirodne ranjivosti predlažu se određena poboljšanja mjera za zaštitu podzemnih voda.

Abstract (english)

A karst area contains high-quality groundwater supplies of enormous value. Due to its features, a karst area is very susceptible to anthropogenic effects, which make it exceptionally vulnerable. The Jadro and Žrnovnica springs catchment area is one of the most noticeable karst area sources in Croatia and one of the biggest basins of the Dinaric karst. Jadro and Žrnovnica springs supply almost the entire Split-Dalmatia County with fresh potable water. This master thesis describes the procedure of analysis the intrinsic vulnerability for the purpose of groundwater protection. The vulnerability was assessed by using the KAVA method. It was modified based on the existing methods for the evaluation of intrinsic vulnerability, and it was developed and tested according to all characteristics of a deep karst aquifer in the Dinaric region. The final evaluation of intrinsic vulnerability by using the KAVA method (evaluation of source vulnerability in this case) is made by using GIS. The KAVA method uses four specific factors in the analysis of intrinsic vulnerability: O - factor (cover layer), P - factor (precipitation effect), I – factor (infiltration effect) and A - factor(aquifer conditions). The obtained results enable making of a final map of source vulnerability (SV index). Based on the final evaluation of intrinsic vulnerability certain actions for groundwater protection are recommended.
