Course description

theoretical and practical knowledge for understanding coastal environments and processes that determine their dynamics and time evolution.
The course aims to provide knowledge related to coastal type classification and dynamics, and to identify coastal issues and measures for their protection and conservation.
At the end of the course, the student will be able to proceed with the analysis of coastal systems.
Based on the acquired knowledge, the student will be able to know the coastal issues and to adopt the best methods of intervention.
At the end of the course, the student will acquire autonomy in dealing with the topics and draw up a paper using the specific scientific language.
The course will allow the acquisition of the fundament of coastal knowledge and the methods for managing in autonomy the consultation of texts and publications (also in English) of specific topics

Prerequisites

None

Tropical coasts: coral reefs, their distribution and origin. Barrier reefs and mangroves.
The glacial coasts dominated by the. The ice action and the permafrost.
The high coasts and their morphoevolution. Coastal cliffs, wave cut platforms and tidal notches.
Coastal investigation by geophysical prospection methods and borehole analysis.
Present-day climate changes and their impacts on the coasts. Sea level rise and future scenarios. Hydrogeology of coasts and coastal subsidence processes.
Coastal risk: high and low coasts erosion, marine flooding processes. Thematic cartography
