Poort, M.C.L. (author)Detailed laboratory measurements of the wave and current field induced by bi-chromatic waves incident on an artificial surfing reef are presented. Strong wave focussing occurs on the surfing reef. Both PTV and in-situ measurements are reported that show the presence of a strong rip current flowing oblique off-shore. Observed water level set-up...master thesis 2007

Crosato, A. (author)Meander migration models include an as yet poorly investigated source of numerical errors related to the computation of the channel curvature, which are amplified by the procedure of adding and deleting grid points as the river planform evolves. The methods adopted to reduce these errors may influence size, form, and migration rate of the...journal article 2007

Rivera Rabelo, I. (author)The objective of this study is to develop methods for extracting and quantifying sedimentary bodies in 3D high-resolution seismic data. A case study was used with an exceptionally high-resolution seismic and a large number of wells: the Palaeocene Tambaredjo field in Suriname. A large-scale interactive 3D visualization system was used to permit...doctoral thesis 2006

Alfaro, E.M. (author)This report presents the analyses and conclusions of a study on the planform evolution of the Geul river in the last 80 years. The results are compared with those of studies carried out by the Vrije Universiteit Amsterdam (VUA). The Geul river is to tributary of the Meuse River (The Netherlands). It has been straightened and protected against...master thesis 2006

Bakker, M. (author)Morphological development was researched along five meanders in the Allier river, France. This includes large scale development of meander form and direction and guiding factors and processes. On a smaller scale channel processes that form morphology, including bars and (secondary) channels. Five meanders in the Allier river, France,...report 2005

Spanjaard, G. (author)The Geul river in the southern part of the Netherlands has had a long history of channel straightening and bank protection, but during the past few decades, large stretches of the Geul have been allowed to meander freely. During fieldwork in June 2003, erosion and sedimentation processes, as well as channelisation measures, were mapped and...report 2004

Buschman, F. (author)AU over the world natui'al lowland rivers and streams are winding tlii'ough the sediments deposited in earlier times. These meandering rivers and streams show remarkable geometric similaiity: the ratio of the meander length to the width of the channel is constant. The process of meandering is thus independent of scale. Many theories and models...report 2004

Teuling, A.J. (author)This study departs from the hypothesis that the often striifing geometric similarity and regularity of meanders is the result of the second law of thermodynamics applied to open dissipative systems. It is argued that along a meandering river the continuous production of entropy is as low and as uniform as possible. An expression of entropy...report 2002

Lancaster, S.Y. (author)A topographic steering river meandering (TSRM) model based on continuity of a simplified flow field through bends is developed. The equilibrium coupling between helical flow and sediment transport, as in Ikeda [1989] determines downstream variation of transverse bed slope. The model tests the hypothesis that meander development patterns can be...report 1998

Blom, A. (author)In this study the river migration model MIANDRAS has been applied to simulations of the planform changes of the river Allier, a tributary of the river Loire in France. The Allier is a very dynamic and natural river system with braided and meandering river sections. Two meandering reaches of the Allier, located between Varennes-sur-Allier and...master thesis 1997

Anonymous, A. (author)In studies of flow structures on single-thread meandering rivers, secondary currents have been shown to have a large influence on the morphological development of meander bends. Until this joint study between FAP 24 and the University of Nottingham, UK, there had been few similar studies carried out on the influence of secondary currents on...report 1996

De Jésus Soriano Pérez, T. (author)The prediction of planform changes is important for the site selection of structure like bridges or intakes. In the design of bank protection works it is indispensable to know future planform developments for the safety of structures and lands. The meander development process consists of translation and expansion of the bends due to bank erosion...report 1994

Simon, A. (author), Hupp, C.R. (author)Hundreds of miles of streams in West Tennessee have been channelized or otherwise modified since the tum of century. After all or parts of a stream are straightened, dredged, or cleared, systematic hydrologic, geomorphic, and ecologic processes collectively begin to reduce energy conditions towards the premodified state. One hundred and .five...report 1992

Taal, M.C. (author)Due to the relatively high computational costs related to the use of 2D models the purpose of this study was to develop a one-dimensional mathematical model that can give a fair estimation of the near-bank deformation and the bedtopography in meandering rivers. The bedtopography is characterized by a point bar-pool configuration that can also be...master thesis 1989

Johannesson, H. (author), Parker, G. (author)A mathematical model is developed for the calculation of flow field and bed topography in curved channels with an erodible bed. A small perturbation approach is used to linearize the governing equations. The downstream convective acceleration of the secondary flow is shown to give rise to a phase lag between secondary flow and channel centerline...report 1988

Beck, S.M. (author)A new model for bed topography is developed herein which accounts for phase lag and the influence of the width to depth ratio. This model is used to analyze four sets of data: two from laboratory channels and two from natural channels. Good agreement is found between the actual and the predicted bed topography. An iterative, two-dimensional...report 1988

The computer model is based on a theoretical approach developed by Ikeda, Parker, and Sawai [1981]. The major objective was to evaluate the overall performance of the...report 1985

Van der Linde, A.A.
