Meyer-Peter, E. (author), Müller, R. (author)In the following paper, a brief summary is first of all given of the results and interpretation of tests already made known in former publications of the Laboratory for Hydraulic Research and Soil Mechanics at the Federal Institute of Technology, Zurich. After that, an attempt is made to derive an empirical law of bed-load transport based on...report 1948

Vinckers, J.B. (author), Bijker, E.W. (author), Schijf, J.B. (author)A new bed-load transportmeter has been designed particularly for very fine bed material (below 400 micron). The basic conception is the same as for the so-called Delft-bottle used for measuring transport by turbulent suspension. The instrument is of the flow-through type. The flow enters through a narrow and relatively high nozzle and is...conference paper 1953

Schijf, J.B. (author), Schönfled, J.C. (author)This paper gives a survey of the theoretical investigations in Holland on the motion of salt and fresh water in estuaries, locks, etc. The insight gained is set forth, and also questions yet unsolved are mentioned. First the long wave phenomena in the interface of two sharply separated liquids are treated, and in connection herewith, the cases...conference paper 1953

Breusers, H.N.C. (author)The time scale of local scour is of importance in many model studies of practical problems. The use of a time scale is justified by the similarity in experimental scouring holes under different conditions. A time scale is derived from experiments with a wide range of length scales, velocity scales and material scales. The influence of velocity...report 1967

Jorissen, R.E. (author), Vrijling, J.K. (author)Downstream a hydraulic construction the original bed of a watercourse is usually protected against scour. This scour is caused by changes of the water movement due to the construction. Nevertheless scour occurs downstream this protection. The scouring process can be described by an empirical relation. The most important parameter of this...report 1989

Hoffmans, G.J.C.M. (author), Booij, R. (author)Excessive local scour can progressively undermine the foundation of a structure. Because complete protection against scour is too expensive generally, the maximum scour-depth and the upstream slope of the scour hole have to be predicted to minimize the risk of failure. In 1961 a systematical research 'tY'ith respect to scour holes started in the...conference paper 1993

(author)The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...conference paper 2001

De Vries, S. (author), De Schipper, M.A. (author), Van Thiel de Vries, J.S.M. (author), Uijttewaal, W.S.L. (author), Stive, M.J.F. (author)The objective of this paper is to demonstrate the use of Stereo Photogrammetry (SP) measuring ship-generated waves and to determine under which conditions they are suitable for surfing. A physical experiment is conducted to gain insight in ship wave behavior under specific conditions. Waves are generated by a hull and are measured using SP. It...conference paper 2008

(author)Scale relations are necessary to choose proper sediment for physical models. The use of lightweight artificial sediment makes it possible to preserve the Reynolds number, Shields number and relative settling velocity altogether. There is also the possibility to preserve the Shields number in combination with the Dean number which would be more...conference paper 2009

Ali, S. (author), Uijttewaal, W.S.J. (author)The Objective of this study is to estimate the form drag due to vegetated weir- like obstacles. Head loss due to submerged vegetated dikes and groins has been modeled by expansion loss form drag model (Energy and momentum balance principles) and it has been compared with experimental data. An experimental study has been carried out on a scaled...conference paper 2009

Blanckaert, K.J.F. (author), McLelland, S.J. (author)Simultaneous velocity measurements were taken using Particle Image Velocimetry (PIV) and an Acoustic Doppler Velocity Profiler (ADVP) in a sharp open-channel bend with an immobile gravel bed. The PIV measures 3D velocity vectors in a vertical plane (~40cm x 20cm) at a frequency of 7.5 Hz, whereas the ADVP measures 3D velocity vectors in a...conference paper 2009

Singh, U. (author), Crosato, A. (author), Giri, S. (author), Hicks, M. (author), Mynett, A. (author)Recent studies have shown that the river bed topography is very sensitive to the composition of bed sediment. So, human interventions and natural processes leading to changes in sediment size grading might result in morphological adjustments of river reaches. This study deals with the effects of changing sediment size grading on the braiding...conference paper 2013

Stecca, G. (author), Blom, A. (author)Modelling the morphodynamic evolution of rivers due to flow-driven sediment transport requires the adoption of a flow model, such as the shallow water equations, and a conservation equation for sediment mass (the Exner equation).
