Open Inverted Filters: Impact of fines content, coefficient of uniformity, and effective stress on inverted geometrically open granular filters in terms of parallel and perpendicular gradients

This study investigates the capacity of an open inverted filter to stabilize the interface between the sand fill and core fill in a rubble mound breakwater. The strength of this filter relies on the arching mechanism of the base material, which is directly influenced by factors such as stability ratio and effective stresses. These forces arise...

Horizontal Slurry Transport on a Large Laboratory Scale

The first head loss prediction methods for hydraulic transport of solids in pipes, date back to the years '50 of last century. The principles are still applied today. Although it is observed that obtained results may differ from reality, when the circumstances do not represent the situation of the original experiment. To investigate this, the...

Critical Pressure during Installation of Suction Caissons in Sand

Suction caissons are used in a variety of bottom founded and floating offshore applications, in shallow and deep waters. The present research focuses on the analysis of suction-assisted installation in sand. Suction pressure measurements from a number of field projects and laboratory centrifuge tests in sandy soils led to find that, in 70% of...
