Experimental Study Of An Artificial
Groundwater Recharging Process

Abstract
Groundwater recharge is gaining ever greater importance in the context of the
management of water resources. This practice can improve the quality of
aquifers, or at any rate temporarily store resources that would otherwise be lost.
The recent stipulation of the \“Piano Direttore”, an extract from the Plan for
Safeguarding Water Resources (\“Piano di Tutela delle Acque”) by the
Commissary appointed to deal with the environmental emergency situation in
Apulia, has removed the prejudicial clause of illegality introduced by the Law
Decree (D. Lgs. 152/99) of allowing rainwater runoff underground.
Nevertheless, this type of plant is still rare in the territory, perhaps due to the
lack of experimental data supporting the efficacy of the procedure. In the
present work the experimental results obtained in an investigation campaign
carried out at a recharge site are illustrated and discussed. The recharge site is
equipped with suitable devices for continuous monitoring of the rainwater levels,
the volume influx to the network, and the variations in the levels of the perched
water. Finally, the experimental data are used as the preliminary settings for a
mathematical model drawn up to represent the phenomenon.
Keywords: aquifer recharge, experimental investigation, mathematical model.
1 Introduction
The recent national and regional norms regulating the dispersion of rainwater
(D.Lgs. 152/99, D. L.vo 258/00 Piano Direttore, an extract of the \“Piano di
Tutela delle Acque”) pose fairly strict limits on rainwater runoff intercepted by
the drainage/sewage system.
Keywords
aquifer recharge, experimental investigation, mathematical model.
