Lo Sfruttamento delle falde freatiche nelle coltri detritiche superficiali come riserve idriche sussidiarie
in regioni granitiche / Oggiano, Giacomo; Giorcelli, Augusto; Ginesu, Sergio. - In: BOLLETTINO DELLA SOCIETÀ SARDA DI SCIENZE NATURALI. - ISSN 0392-6710. - 23:1984(1984), pp. 7-20.
abstract:
The study of some catch-basins upstream to some headwaters
has been carried out on the southern slope of the «Monti di
Alà» chaine. The characteristics of some springs with a scarse flow have been also investigated.The data obtained allow us to frame the various source areas
as gravity springs. The interception of the underground flows operated by some draining trenches has permitted, in a further moment, a considerable increase of flow, compared with the natural one. In consideration of this result, the catch basins consisting of surficial detrital sheet coming from the alteration of granites, assume a certain significance as subsidiary water reserve in some areas lacking in good aquifers as the granitic domains.
