A Technical Note on the Application of a Water Budget Model at Regional Scale: A Water Manager’s Approach towards a Sustainable Water Resources Management

Abstract

Evaluating the quantitative status of groundwater has always represented an attractive method of modelling development for scientific research purposes and, at the same time, an essential planning tool for water managers. Today, in addition to the traditional modelling and management applications, the quantification of groundwater resources increasingly aims at evaluating effective water bodies’ health. In fact, the founding principles introduced by the most recent international directives in terms of water protection are specifically addressed to natural ecosystems’ protection complying with different socio-economic conditions. In this context, Acea Ato2, a water utility operating in central Italy, here proposes the implementation of an analytical water budget model for the assessment of the groundwater potential recharge status throughout its managed area.
