ANALYSIS OF THE MORPHOMETRIC CHARACTERISTICS WITHIN CLUJ-NAPOCA USING G.I.S.

Abstract

The aim of our research was to investigate the way in which the morphometric characteristics influence the excess moisture. For this purpose, a study area was chosen representing the administrative territorial unit of Cluj-Napoca, within this perimeter several landslides, erosional processes and excess moisture on the slopes are manifesting. The databases created in the present study, which are materialized in maps and table databases, can become the backbone for elaborating landscaping projects, taking decisions regarding designing and realizing land improvements works, eliminating excess moisture works and soil erosion control works. Also, the analysis includes the perimeter known as the Feleac Farm, where several studies regarding the slope leaks regularization and anti-erosion organization works have been conducted. Within the G.I.S. spatial analysis nine essential morphometric characteristics have been analysed: hypsometry, slope, aspect, depth of fragmentation, density of fragmentation, wetness index, stream power index, as well as the plan and profile curvature. The link between the above mentioned morphometric characteristics and the excess moisture has been analysed.
