GIS (Geographic information System) techniques, characterized by high accuracy of mapping and measurement, prove to be a competent tool in morphometric analysis. The main goal of the study is to analyze the hydrographic network in linear form (vector) by overlaying databases from different periods (vector layer made in 2003 and layer made in 2017) for a regional case study within Southwestern Romania. The database organized in layers aims to reproduce characteristics of the drainage network: the cartographic maps scale 1: 100.000, Geo-referenced in ArcGIS 10.4); the first version of the hydrographic network used in the first River Basin. The results of this analysis will be concentrated on the length of the river network correlated with the two layers and also on the relief based on a DTM (cell size 5×5 m) within the study area. The relevance of the discussions lies in highlighting the differences appeared over time regarding the hydrographic network spatially using GIS based quantitative morphometric analysis.
