Characteristics of the Relief System within the Istrian Hummocy Hills - Factor Approach
Darko Mihljević
Abstract
Geomorphological system of the Istrian hummocky hills has been explored by means of the ''r'' type factor analysis. Four fundamental factors have been exctracted. They explain 69,93% of total system variability, and together with the fifth unique factor they account. Analysis of the morphometric maps with initial variables shows that the extreme values of the vallys network parameters are connected with the upstream catchment area of the main third order valleys, which have been drained twards the SW part of the Ćepić polje basin. By interpretation of isofactor maps it may be concluded the unbalance within single geomorphological subsystems was caused by sudden fluctuation of sea level during the late Würm and Holocene, by the recent subsidence of the Ćepić polje basin bottom and finally by the left horizontal strike slip and a dip slip shift component of Pazin fault.
