The theory of the hydraulics of closed conduit spillways has been given in Part I of this report series. Parts II to VII, giving results of tests on several forms of the closed conduit spillway and discussion of vortices, have also been published. Parts VIII and IX, presented in this paper, report the results of tests on a number of additional forms of the closed conduit spillway. In contrast to the general tests reported in prior Parts, the tests reported here are model tests of specific field structures and actual field tests of full size structures. The results have been presented in such a way that they have general application to the design of the type of structure they represent.
