Abstract
Abstract In the article, river bed research was conducted in the Neverice channel near the city of Nitra, Slovak Republic. Relationships of morphometric parameters in Neverice channel were studied based on GIS technologies. Orthophotomosaic images created by National Forest Center (NLC) and Geodetic and Cartographic Institute Bratislava (GKÚ) were used. Downloaded images were analyzed using ArcGIS Pro software. In the analysis 3 characteristic blocks were selected along the length of the channel. The cross-sections surface of the channel is drawn for each frame and the slope of the channel bottom is determined. The DEM model was used to determine the slope of the channel bottom and 3D model is created. The changes taking place in the river bed are analyzed and conclusions are presented.
