modelling of water movements[BR] - management of water resources [BR] - modelling and planning of water outflow [BR] - Hydrology - Water Resources Management - Hydraulic Flow Modelling and Lay-Out - Hydrology
This class is made of theoretical lectures (ex-cathedra) and practical exercises partially supervised during which an assistant is at the students¿ disposal to answer their questions. Each exercise leads to the handling in of a report. This class fit in the continuity of the basic classes of applied hydraulics (free surface flows) by treating subjects more complex and more specialized such as the analysis of the turbulence and of the mathematical models currently available to represent it, sediments transport by the rivers or waves induced by bad working of structures (failure of dams for example), with risk analysis. These subjects are applied in practical works through the use of the quasi-3D free surface flow solver WOLF2D or the writing of a solver for the computation of bed-load transport. Other aspects of unsteady hydrodynamics are considered by the hydraulic calculation of a network system for locks operation.
Hydraulic Flow Modelling and Lay-Out
Principales notions sur les aménagements hydroélectriques et les écoulements non permanents Différents types d'aménagements - Nécessités des cheminées d'équilibre - Coup de bélier (Etude théorique et numérique). Cheminées d'équilibre (Etude théorique et numérique). Cas d'application pratique. Rentabilité économique de l'énergie hydroélectrique dans les systèmes de production d'énergie. Planification et réalisation des travaux.
Hydrology
Quality control and homogenisation of the hydropluviometric data. Maximisation of the information of flows by probabilistic models. Statistical analysis of annual and monthly discharges. Study of extreme situations during floods and drought periods. Studies of floods by mathematical, deterministic, probabilistic, or conceptual models based on spatial discretion. Reconstitution of complex hydrographs. Predetermination of the exceptional floods in small and large basins..
Course objective :
Hydrology
To develop basic elements in order to learn how to establish correctly a water balance and to evaluate the maximum floods which can occur in a watershed.
Prerequisites :
Hydrology
No specific prerequisite apart from what is normally expected of students in their fourth year at university.
Workshops :
Hydrology
Resolution of particular problems and establishment of a complete water balance of a basin. Four workshops of guided exercises and two personal working sessions are organised.
Organization :
Water Resources Management
1st semester
Hydraulic Flow Modelling and Lay-Out
1er semestre
Hydrology
First term.
Written notes :
Water Resources Management
Comprehensive typing out lecture notes (814 pages) available.
Hydrology
Notes will be handed out to students on our first meeting.
Assessment :
Water Resources Management
Each practical work report provides an individual appreciation.An oral presentation of the practical works and an oral evaluation for the whole lecture are scheduled at the end of the module. The last one is made up of theoretical and application questions.Final mark is obtained by weighted mixing of the partial appreciations.
Hydrology
Oral examination and evaluation of personal practical work.
