Abstract

Main aim of the paper was inundation 2D modeling of gravel-bed and lateral dynamic Topľa River in flysch Western Carpathians. Results points to 473.20 ha of flooded area during flood event from 2010 with recurrence interval 100 years. Average water depth on floodplain in the river channel was 0.7 m and 2.8 m. Extent of the inundation during one-year recurrence interval was 160.8 ha, which was flooded during low magnitude floods. Knowledge of the long-term evolution of river morphology and hydraulic modeling is a major challenge for the understanding of river ecosystems in the future and application of such kind of interventions that lead to improving ecological status of ecosystem and minimizing the negative effects of floods.
