Geographic information system technologies in the study of deformation in rivers
Аннотация
The article examines the possibilities of assessing the changes and condition of the riverbed using remote sensing (RS) and geoinformation systems (GIS) technologies. Deformation processes observed in the last 25 years in the Sox stream bed selected as a research object were evaluated on the basis of modern geoinformation systems. The processes taking place in River were studied on the basis of satellite data. Landsat satellite generations were selected for analysis. To download the data, the official site of GloVis, which is widely used today, was used. The data was analyzed using the ArcMap software. The results of GIS analysis were compared with field experiments. In the last 20 years, the direction of the flow along the right bank has changed, the left bank sections are covered with silt particles, grass growth and washing processes are observed on the left bank. Over the past 5 years, 30 m of cultivated land has been washed away along the right bank between PK 3 and PK 4. These changes average 4-5 m per year. The deformation processes observed in the river are analyzed and conclusions are drawn.
