Oscillazioni libere del lago di Bracciano: loro caratteristiche e loro energia

Abstract

The present third contribution to the studyof free oscillations of Lalce Bracciano expoundsthe principles on ivliich the functioningof limnographs is based and describesthe features of the type of limnograph atpresent in use on the laTces of Central Italy.Next, the energy associated with a free oscillationis outlined and the way of determiningit is indicated. The seiches of Lake Braccianoare generally of small amplitude. Asregards tlie free uninodale assymmetric oscillation,it is demonstrated that the averageenergy associated with this type of seichereaches about 44 kWh.
