Abstract

Strme padine sjeverozapadnog dijela Medvednice podložne su derazijskim i
fluviodenudacijskim procesima koji formiraju velik broj jaruga i V-dolina. U podnožju tog
područja nalaze se plavine na kojima se nalazi veći broj naselja kojima nerijetko prijete
bujične poplave. Cilj ovog rada bio je kvantitativnim metodama analizirati morfometrijska
obilježja uz pomoć digitalnog modela reljefa, topografske i geološke karte. Analizirana su
četiri drenažna bazena unutar kojih su utvrđena područja intenzivnih erozijskih procesa kao
rezultat geološke građe, velikih visinskih razlika, ekspozicije te strmih padina dolina.
Drenažni bazeni odlikuju se nepropusnom podlogom na kojoj je formirana površinska
drenažna mreža, a glavni tokovi potoka pružaju se najvećim dijelom duž rasjednih linija.
Također su analizirane pripadajuće plavine koje se odlikuju nižim nagibima i energijama
reljefa te su ujedno i područja akumulacije aluvijalnog materijala pleistocenske i holocenske
starosti.

Abstract (english)

The steep slopes of the northwestern part of Medvednica are susceptible to
fluviodenudational processes, which form a large number of gullies and V-shaped valleys. At
the base of this area, there are alluvial fans on which large number of settlements are located
and often threatened by flash floods. The aim of this study was to analyse morphometric
characteristics using quantitative methods on digital elevation model, topographic and
geological map. Four drainage basins were analysed, which are areas of intense erosion
processes as a result of geological structure, altitude differences, exposure and steep slopes
The drainage basins are characterized by impermeable rocks that have formed a drainage
network, and the main stream channels mostly flow through fault lines. Additionally, the
corresponding fans were digitized and analysed, characterized by lower gradients of slopes
and relief energies, so they are areas of intensive accumulation of alluvial material of
Pleistocene and Holocene age.
