Direct Measurements of Hydrodynamic Forces Induced by Tidal Bores
Water Resources Research, 2021 Tidal bores are sudden discontinuities in water depth, and can be classified as undular and breaking bores when tidal waves propagate upstream in a river mouth and on beaches.

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1908 Abstract It was shown long ago by Airy that when waves advance over shallow water of depth originally uniform, the crests tend to gain upon the hollows, so that the anterior slopes become steeper and steeper. Ultimately, if the conditions are favourable, there formed what is be may called a bore.

Low speed doubly salient permanent magnet generator with passive rotor for a tidal current turbine [PDF]
, 2013 This paper presents a low speed permanent magnet generator that can be associated with a tidal turbine. This structure has a passive rotor which leads to a simple and robust structural solution. The principle of operation and an electromecanical model of
