Bijker, E.W. (author)11th Conference on Coastal Engineering in London 1968, the author presented a method for computing the littoral drift starting from the longshore current velocity as this is generated by the waves and with the assumption that the material is stirred up by the waves. In this paper measurements in a model basin are described by which the procedure...report 1971

Snel, H. (author)A novel method is presented for the calculation of the flow field induced by a turbulent jet exhausting into a uniform cross flow. Outside the jet boimdary, potential flow is assumed. The jet effects are represented by a source distribution on the jet boundary. The boundary conditions on the jet boundary (normal velocity) are calculated from a...report 1973

Snel, H. (author)A model is derived for the calculation of the properties of a jet exhausting into a non-uniform main flow, at an arbitrary angle to the initial jet direction. The model is a generalisation of an earlier jet-ina-main flow model for uniform main flows. Semi empirical input is limited to an entrainment relation and a relation for form factors of...report 1975

Goda, Y. (author), Kishara, Y. (author), Kamiyama, Y. (author)Series of measurements with irregular waves were undertaken for model seawalls of vertical walls with and without protection by concrete block mounds. Experimental data were compared and supplemented with theoretical calculations by the combination of the author's random wave breaking model in shallow waters and the weir type overflow model. The...report 1975

Vlieger, H. (author)Past experience has shown that during the operational life of an aircraft structure cracks or failures may arise in different structural components. In future designs the designer must be able on the one hand to restrict the occurrence of cracks by a careful detail design and on the other hand to guarantee some specified life of the aircraft if...report 1976

Kooi, J.W. (author)An experiment is described in which a nominal normal shock impinges on a turbulent flat plate boundary layer. The wall pressure distribution in the interaction region was measured for Mach numbers in front of the shock of 1.40, 1.44 and 1.46. The Reynolds number based on shock position was 18 X 10(6) and based on momentum thickness at the start...report 1978

(author)For the effective performance of its work, the Rijkswaterstaat, which has a staff of about 12.000, consists of 25 Directorates with different duties. One of them is the Meetkundige Dienst (Survey Department) with a staff of about 500, which is charged with the geodetic support of the Rijkswaterstaat. Part of this support is the preparation of...report 1980

Li, Y.C. (author), Herbich, J.B. (author)The interaction of a gravity wave with a steady uniform current is discussed in this paper. Analysis indicates there is no dominant difference in the results obtained when employing either the equation of conservation of wave energy flux or the equation of conservation of wave action flux. Numerical calculations of the wave length change by...report 1982
