Topography plays an unraveled role in many biophysical processes and phenomena. The main problem, however, is that measurement, representation, and characterization of such a vast and continuous feature are very challenging. The accuracy of Digital Elevation Models (DEMs) has a direct influence on the results of the further landform analysis. In this paper, we use existing approaches of landform analysis with the use of global DEMs in the large-scale regional study. A detailed comparison was made between landforms...

Human impact along with other elements of the environment has a great impact on the processes in the river basins. River meander dynamics and mobility are important indicators of environmental change related to climate changes and anthropogenic activities at local and river basin scales. This paper presents a study of spatial and temporal changes meandering Alazani (Georgia) in its middle stream and downstream. Alazani is the border of the country and the bank erosion here has the environmental and political impor...

The world modernization, global development, maximum utilization of minerals and ruthless treatment of the environment by humans have created many environmental problems around the world, and Georgia is no exception. One of the richest deposits in Georgia are in Bolnisi, where the RMG (formerly Madneuli) mine is functioning, located in Kazreti, on the right bank of the Mashavera River. Open-pit mining processes causes soil and water contamination, which do harms to human health and ecosystem. Remediation projects ...
