During normal conditions the Itajaí-Açu River is a rather calm river that is used for navigation and the harbour area. Recovering from the past two floods in 2008 and 2011 have cost more than...

Probabilistic coastal vulnerability assessment to storms at regional scale: Application to the coast at North-East Aegean Sea (Thrakiko Pelagos), Greece

In this study, a probabilistic vulnerability assessment to the impact of storms in the coast of Thrace, Greece was carried out. To this end, the methodology presented by Bosom and Jiménez (2011) has been applied with some modifications. The introduced modifications, for this work, were the use of a different run-up model to deal with the...

Winnowing: Sub-surface entrainment of particles

This research focusses on the behaviour of fine particles which pass through the armour layer of bed material of the upper and middle reaches of a river. When the fine particles are entrained in the armour layer, it is described as ‘winnowing’ or vertical entrainment. A river bed generally consists of a coarse surface layer, which is the...
