Discussion of bedload movement formulas of Kalinske, Einstein and Meyer-Peter and Müller and their application to recent measurements of beload in the rivers in Holland

Overview of sediment transport formulas and comparison with measurements in Waal and Rijn river in the Netherlands.

River studies and recommendations on improvement of Niger and Benué

Extensive study or the rivers Niger and Benué in order to describe the hydraulics and morphology with the aim to improve inland navigation in Nigeria. Part I gives a summary of the original NEDECO studies and their results as contained in the Report, without summarising the information obtained from other sources. This is followed by a...

Seismic redatuming with transmission loss correction in complex media

Traditionally redatuming algorithms disregard amplitude information carried by seismic reflections, they focus just on traveltime information. Properly processing amplitude information requires much more computing resources. We develop an algorithm for redatuming that aims to preserve amplitude information. We aim to observe energy conservation...

Quantitative Image Analysis for Evaluating the Coating Thickness and Pore Distribution in Coated Small Particles

Purpose This study aims to develop a characterization method for coating structure based on image analysis, which is particularly promising for the rational design of coated particles in the pharmaceutical industry. Methods The method applies the MATLAB image processing toolbox to images of coated particles taken with Confocal Laser Scanning...

Reciprocity Theorems for One-Way Wave Fields in Curvilinear Coordinate Systems

One-way wave equations conveniently describe wave propagation in media with discontinuous and/or rapid variations in one direction, but with smooth and slow variations in the complementary transverse directions. In the past, reciprocity theorems have been developed in terms of one-way wave fields. The boundaries of the integration volumes and...

Data matching for free-surface multiple attenuation by multidimensional deconvolution

A common strategy for surface-related multiple elimination of seismic data is to predict multiples by a convolutional model and subtract these adaptively from the input gathers. Problems can be posed by interfering multiples and primaries. Removing multiples by multidimensional deconvolution (MDD) (inversion) does not suffer from these problems....
