From doline distribution to tectonic movements. Example of the Velebit mountain range, Croatia

The influence of tectonic forces on karst relief developement has been studied using dolines as geomorphological markers. The strain and stress orientations have been calculated from the doline distribution, applaying the centre to centre method. 623 local results have been obtined which were later injected into 2D finite element model created in Castem 2000 software. As the observed deformations are the consequence of the tectonic displacements, the numerical model tends to simulate the tectonic conditions, which are closely related to the observed deformations. The trsults were correlated with the GPS measurements as well as with geological field mapping results and great coincidence was observed.
