Elementi di geologia applicata e idrogeologia - Idrogeologia

The area included in Sheet 337 "Norcia" covers two distinct hydrographic domains and hydrogeological, having very different characteristics in terms of hydrogeological productivity and direction of surface and underground outflows: a western sector, where the carbonate units of the Reatini and Sibillini Mountains prevail, and a sector east, where the Laga formation is predominant (Fig. 115). The western portion is drained by the Nera and Corno rivers, tributaries of the Tiber, while the portion east is drained by the Tronto River. Of particular interest is the transition band between the two domains, where the main sources of the spring are present area. The hydrological and hydrogeological characteristics will be illustrated below of the two domains; the hydrogeological complexes, the main ones, will also be listed and described hydrogeological structures, the main underground flow directions and sources of the study area.
