The use of satellite images in the morphological analysis of the Siret riverbed between Cosmești and Galaţi

The objective of this work consists in identifying the changes produced in the Siret River, using satellite images. The study area is represented by a sector of the Siret Plain, heavily influenced by the dynamics of the Siret River reflected in morphology, landscape features, land use, and anthropogenic elements. The working methodology consisted in combining the techniques of remote sensing and GIS in the processing of satellite images Landsat 7 ETM and OLI L8 from 2003 and 2016, aiming the classification of this images according to a few categories of land use in order to observe the dynamics of their distribution in space and time. The main categories of use of land on which we have focused the analysis are located in close proximity to bodies of water. To process images in different spectral bands combinations and vector analysis, we used ArcGis application and related modules. The results of the analysis of satellite images based on processing, are represented by small differences identified between the categories of land use in the proximityy of the Siret River within the area studied, between the years of 2003-2016.
