Terrain is one of the factors determining the processes occurring in the Earth's crust surface. The hipsometry of a watershed has a major impact on hydrological processes, on geomorphology, soil and even its biological context [18]. The study of the landforms commonly is done by direct observation in the field, and by interpreting aerial photographs and topographic maps. They are well known advantages of Geographic Information Systems application in terrain analysis using Digital Elevation Models. This paper analyzes the various morphometric indices of terrain with involvement in triggering the various geomorphological hazards, such as soil erosion. For exampliifcation, it has selected a small area from the Middle Prut Plain, with limits (EPSG: 4026): Point 1 (134,860.0, 286,496.0); Point 2 (142,360.0, 286,496.0); Point 3 (142,360.0, 278,996.0); Point 4 (134,860.0, 278,996.0).
