Rezumat:

An analytic study based on asymptotic expansions exhibits a difference in the behaviour of a standard hydraulic scheme including a surge tank,depending upon the ratio v=(l1/c1)/l2/c2),where l1,l2 are the legths of the tunnel and penstok respectively and c1,c2 the corresponding velocities; if v=p/q is an irreductible fraction and if p is odd,transients are damped out,while if p is even,there is an oscillatory mode.
