We present a new set of experiments in local scour due to confined twin propeller jets aiming include driving characteristics the analysis scouring action during in-port manoeuvres. The maximum depth is studied as function bed clearance, wall clearance and efflux velocity jet. Aiming reproduce more realistic manoeuvres, both forward backward rotation propellers are analysed showing different be...

All coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety stressors. The West Antarctic Peninsula is hotspot physical climate change has experienced dramatic loss sea-ice glaciers in recent years. Among other things, immobilizes icebergs, reducing collisions between icebergs seabed, thus decreasing ice-scouring. Ic...

The paper presents the results of an experimental investigation of fluvial groynes conducted on a mobile bed scale model. The model reproduces a reach of the River Po, Italy, in which a series of groynes have been designed to improve navigability during dry periods. The experiments were conducted using light plastic material. The density and the grain size of the material were calibrated accord...

The modeling of flood-induced bend scour near embankment toes can provide important information for river engineering, embankment safety warnings, and emergency action management. During the rainy seasons, short-term general scour and bend scour are the most common causes for the failure of reinforced concrete embankments in Taiwan. To gain a deeper understanding of the scouring process near le...

We present indirect constraints on the stellar initial-mass-function (IMF) in nine massive elliptical galaxies with σ ≈ 300 km/s, via a comparison of dynamical and stellarpopulation based stellar masses. We use adaptive-optics assisted, high resolution kinematical data from the SINFONI Search for Supermassive Black Holes that allow us to constrain the dynamical stellar mass-to-light ratio in th...
