There is no news that the use of GIS technique in the engineering field takes place at high level, and has a very well defined place in environment engineering. This paper shows a sequence of a GIS application in the field of quantification of soil loss as a result of water erosion The GIS application is exemplified in a water catchment of approximately 4000 ha in Berheci Superior of Bacau County, with intensive water erosion processes, both at the surface and in gullies. After the development of databases (graphic and alphanumerical), the determination of connections (keys) between them is very important, in order to enable interrogation. Interrogation ensures the value of GIS application, and in this application we can notice 2 interrogation methods. The development method of the interrogations, as well as the response manner in the own designed concept, with a relational alphanumerical database are shown. This paper shows the importance of correlated databases in the context of statistical analyses for large areas. Following these analyses and by means of the GIS, the most intelligent ecologic and anti-erosional management solutions can be taken in torrential hydrographic water catchments.
