Abstract

Strukturno geomorfološki procesi izrazito su bitni za oblikovanje reljefa, međutim determiniranje tektonski aktivnih područja, tj. aktivnih rasjeda izrazito je kompleksan problem. U novije vrijeme kao indikator pomaka i aktivnosti rasjeda može se koristi vijugavost rijeka. U ovome radu istražena je vijugavost toka rijeke Drave kako bi se istražila tektonska aktivnost. Na vijugavost toka rijeke Drave na području Hrvatske utječu tri rasjedne zone, Periadriatsko – Dravski rasjed, Dravski rasjed, te rasjedi na području Mađarske koji direktno presijecaju tok rijeke. Rijeka Drava svoj tok mijenja većinski pod utjecajem pomaka rasjeda koji su prostorno bliži njenom toku. Na sjeveru Hrvatske dolazi do izravnog presijecanja toka rijeke Drave rasjedima, pa taj dio toka ima veću vijugavost od ostalih dijelova Drave. Iz ovog rada je vidljivo da je vijugavost dobar indikator tektonske aktivnosti jer se povećava u blizini aktivnih rasjeda.

Abstract (english)

Structural geomorphological processes are critically important for shaping the landscape; however, determining tectonically active areas, particularly faults, is a highly complex problem. Recently, river sinuosity has been used as a measure for identifying fault displacements and activities. In this work, the sinuosity of the Drava River was investigated to demonstrate the tectonic activity of faults. The meandering of the Drava River in the Croatian region is influenced by three fault zones: the Periadriatic-Drava Fault, the Drava Fault, and the normal faults in Hungary that directly intersect the river's course. The Drava River changes its course primarily under the influence of fault shifts that are spatially closer to its flow, while in Northern Croatia, the river's course is directly intersected, resulting in this section having greater sinuosity compared to other parts of the Drava's flow .It has been proven that sinuosity is a good indicator of tectonic activity, as it increases in areas where faults are tectonically active and exhibit greater fault plane displacements.
