Sommario
Si considera il modo ondoso bidimensionale dovuto ad un impulso lungo la linea che si muove sulla superficie di una corrente a profondità finita. L'integrale dell'onda è valutato per grandi distanze e tempi con l'aiuto di funzioni generalizzate. Sono studiati alcuni casi particolari e vengono discussi alcuni aspetti fisici del moto ondoso.
Summary
The two dimensional wave motion due to a line impulse moving on the surface of a running stream of finite depth is considered. The wave integral is evaluated for large times and distances with the help of generalized functions. Some particular cases are considered and some physical aspects of the wave motion are discussed.
