Descriptif
After the course the student should be able to - - use the basics of fluvial flows and tidal dynamics. - - understand the dynamics of atmospheric , fluvial or marine boundary layers - - understand the meteorological forcing and its variability - - estimate the wind, the fluvial or tidal energy potential of a particular site or region - - make the distinction between the amount of energy and the power available \- quantify the resource’s availability and its variability **Eligibility/Pre-requisites:** Basic knowledge in fluid mechanics, Bernoulli and Navier-Stokes equations. **Course main content:** The course is divided in three blocs dedicated to hydro , wind and marine resources. **1. 1 Introduction** \- Economical, environmental and political issues \- Various units of energy, primary and final energy, capacity of some power plants 1\. **2 Hydroelectric resource** \- Water cycle, potential temperature, precipitations \- Gravitational energy: resource and energy \- Conventional dam: principle, efficiency, power capacity, capacity factor \- The mean total head H, head loss, maximum flow rate and power \- Environmental impact and carbon budget of hydroelectric power plants **2.
