Learning objectives
<br />The aim of the course is to complement the basic hydrologic concepts (acquired in the course “Idrologia”) and to develop the main topics concerning basin management plans, mainly with reference to flood defence. To complete also the knowledge of flood control measures in mountain streams and in plain rivers.
Prerequisites
Idraulica AB, Idrologia, Protezione idraulica del territorio
