Abstract

Krški vodonosnici su spremnici podzemne vode vrlo visoke kakvoće. Zbog svoje hidrogeološke građe vrlo su osjetljivi na antropogene utjecaje. Zbog toga zahtijevaju mjere zaštite dobivene na temelju rezultata detaljnih istraživanja te korištenjem metoda procjene prirodne ranjivosti vodonosnika. Takve metode temelje se na pretpostavci da prirodna kemijska, biološka i fizikalna svojstva nekog područja mogu u određenoj mjeri doprinijeti zaštiti podzemnih voda od vanjskih utjecaja. Jedna od mnogih razvijenih metoda je KAVA metoda koja je predstavljena u radu i primijenjena na području sliva Bokanjac – Poličnik. Radi se o multiparametarskoj metodi koja služi za procjenu prirodne ranjivosti područja (vodonosnika i/ili izvorišta) a konačni rezultat su karte izrađene pomoću GIS alata. KAVA metoda koristi četiri parametra: pokrovne naslage (O), uvjeti vodonosnika (A), utjecaj infiltracije (I) i utjecaj oborina (P). Svaki od parametara procjenjuje se pomoću podfaktora. Također, uz kartu ranjivosti izrađene su karta opasnosti i karta rizika od onečišćenja podzemnih voda pod utjecajem poljoprivredne proizvodnje.

Abstract (english)

Karst aquifers are reservoirs of high quality groundwater. Due to their hydrogeological structure, they are very vulnerable to anthropogenic influences. Therefore, they require protection measures defined on the basis of the results of detailed research and using methods for assessing the natural vulnerability of aquifers. Such methods are based on the assumption that the natural chemical, biological and physical properties of an area may, to some extent, contribute to the protection of groundwater from external influences. One of the many developed methods is the KAVA method which is presented in the paper and applied in the Bokanjac - Poličnik basin. KAVA is multiparameter method used to assess the intrinsic vulnerability of the area (aquifers and /or springs) and the final result are maps made using GIS tools. The KAVA method uses four parameters: cover deposits (O), infiltration impact (I), aquifer conditions (A), and precipitation impact (P). Each of the parameters is estimated using subfactors. In addition to the vulnerability map, a hazard map and a groundwater pollution risk map under the influence of agricultural production were prepared.
