Littoral drift computations on mutual wave and current influence
No full text11th 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 is further tested. A comparison with littoral drift rates computed by this procedure and derived from accretion and erosion rates along the coast of Queensland (Australia) are presented. For a hypothetical coast the littoral transports with varying bed roughness are computed. The influence of this roughness on the assumptions forming the basis of the computation procedure is discussed.Hydraulic EngineeringCivil Engineering and Geoscience

Scour underneath submarine pipelines
No full textThis report deals with the physical experiments on scour underneath submarine pipelines, carried out as part of the MaTS project on the stability of submarine pipelines. Moreover, these experiments, which have been carried out in the laboratory for fluid mechanics of the Department of Civil Engineering of the Delft University of Technology, are the topic of the student thesis of the author, who has been joining the Group of Coastal Engineering as a student assistant. His work has been accompanied by ir. W. Leeuwestein. Prof.dr.ir.E.W.Bijker was the supervisor of the entire project on the stability of pipelines. After the introduction in chapter 2, in chapter 3 a summing up is given of the previous research on the subject and the theory needed to approach the problem of the scour process underneath pipelines. In the following chapter a description is given of the way in which the experiments have been carried out. Chapter 5 gives the results of the experiments and using the results a functional relation has been tried to find between the scour depth on the one hand and the flow, pipe and sand parameters on the other hand. In chapter 6 the use of physical experiments to predict prototype scour depths is discussed by studying the concerning scale relations. This thesis ends with some conclusions.Civil Engineering and Geoscience
