The objective of the study is to develop a Geographic Information System (GIS) model which integrates a lot of information and various types of data required for hydrographic and geomorphologic analyses, applicable in the sphere of hydrology and geomorphology. The case study will show how to use a GIS tool, create a Digital Elevation Model (DEM), using terrain information, contours line with height information attached and rivers, and at the end to obtain watershed boundaries and determine which basins have higher possibility of flooding by analysis of its shape. The raw data (primary database) will be obtained through vectorization from different maps used for analysing the geographic characteristics of the studied area. The paper focuses on prevention of potential disasters (floods), providing support in data collection and processing by transposing the real geographical problems in a computerassisted modelling.
