G.I.S. techniques used in the analysis of the morphometrical parameters of the Red Lake drainage basin

Abstract

Red Lake in Hăghimaş Mountains was formed by the natural barrage of the Bicaz brook in 1837. It is one of the most interesting lakes of this type in Romania, and that is why scientists from all fields are interested in it. In order to realize the morphometrical analysis, the most modern methods and computerized programs have been used. The cartographic material is represented by the topographical maps drawn in 1972 and reambulated in 1990. For the whole river basin four topographical maps have been used, on the scale 1:25 000. The software we have used is Microimages – TNTmips. By means of this program a series of vectors layers with different destinations have been realized. The cartographic material we have realized for the morphometrical analysis of Red Lake river basin points out the limit of the river basin, the hydrographical network, the landforms fragmentation, the water courses order, the slope value, the slope orientation etc. The vectorial layer for the contour lines represented the support of the land numeric model (MNT). The resulted thematic maps emphasize the landscape value in this area and its hydrological importance.
