The Tevere river basin was schematically subdivided into several main sectors, with different hydrostructural characteristics,and the authors have been carried out a detailed study in the Colli Albani volcanic area that contains an important acquifer of which an hydrogeological balance calculations were executed. The calculations were computed analyzing the spatial and temporal variability of precipitations and climatic conditions, analyzing the effects of morphological, lithological, pedological conditions and land use on runoff and evapotraspiration with elevated spatial detail, estimating the withdrawals. This method allow to determine the ratio between withdrawals and effective infiltration
