Abstract

Na prisojnim padinama Medvednice ukupno je kartirano 900 izvora, čime je utvrđeno da je njihov broj višestruko veći od prethodno smatranog. Izdašnost izvora uglavnom je manja od 1 L/s, pri čemu je najviše izvora izdašnosti od 0,01 do 0,1 L/s. Broj izvora smanjuje se s udaljavanjem od poznatih rasjeda i kontaktnih zona. Utvrđene su razlike u broju i gustoći izvora s obzirom na litostratigrafske jedinice prostora istraživanja, pri čemu se najveći broj izvora javlja na području parametamorfnih stijena devonske i karbonske starosti. Najveća gustoća izvora zabilježena je na području paleogenskih konglomerata i pješčenjaka. Što se tiče morfometrijskih obilježja, izvori se najčešće javljaju na konkavnim i konvergentnim padinama, odnosno na padinama nagiba od 12° do 32°. Većini izvora određeni su tipovi, pri čemu su najzastupljeniji helokreni izvori. Praćenjem nekoliko izvora utvrđena su njihova hidrološka i fizikalno-kemijska svojstva. Zabilježen je i utjecaj tretiranja prometnica sredstvima protiv zaleđivanja na kakvoću vode.

Abstract (english)

Exactly 900 springs have been mapped on the southern slopes of the Medvednica mountain, and it was found that their number is much higher than previously assumed. The discharge of the springs is generally less than 1 l/s, with most springs discharging between 0,01 and 0,1 l/s. The number of springs decreases with distance from known faults and contact zones. Differences in the number and density of springs were determined with respect to the lithostratigraphic units of the study area, with the largest number of springs occurring in the area of parametamorphic rocks of Devonian and Carboniferous age. The highest density was found in the area of Paleogene conglomerates and sandstones. In terms of morphometric characteristics, the springs occur most frequently on concave and convergent slopes and on slopes with an inclination from 12° to 32°. The type was determined for most of the springs, with helocrene springs being the most common. By monitoring several springs, their hydrological and physico-chemical characteristics were determined. The effects of the treatment of roads with de-icing agents on water quality were also recorded.
