Identification and Geovisualization of Morphological-hydrographic characteristics of the Jala River Basin

Abstract

The paper identifies and geovisualizes the morphological and hydrographic features of the Jala River Basin. Based on the AW3D30 Digital Surface Model, released in 2018 by the Japan Aerospace Exploration Agency (JAXA), a 10-meter DEM of the Jala Basin and terrain slope and exposure models were prepared. Hydrographic characteristics of the basin were interpreted on the basis of morphometric analysis of the basin, using a topographic map scale 1:25,000, issued in 1976 by the Military Geographical Institute from Belgrade, and based on hydroclimatic data of the Federal Hydrometeorological Institute from Sarajevo.Using methods and algorithms integrated in QGIS, raster and vector values of the most important indicators of recent morphological and hydrographic features of the Jala basin (hypsometry, slope and aspect, hydrographic system and network, etc.) were obtained, after which their analytical-synthetic interpretation and geovisualization was performed.Five thematic maps and three terrain profiles have been prepared, which essentially illustrate the treated morphological and hydrographic indicators of the basin, which are indispensable in urban planning, regulation and arrangement of the Jala riverbed and tributaries, landslide remediation in the basin, etc.
