| Course contents : | This class fits directly into the continuity of the class Applied hydraulics I by treating the unsteady part of the free surface flows and by paying particular attention to the methods for global management of hydrographic catchments. It enters in this way the problem of floods genesis and propagation.It is made of theoretical lectures (ex cathedra) and practical supervised exercises during which an assistant is at the students disposal to answer their questions. Each exercise leads to the handling in of a report. The subjects treated are as follow, with the numbers of the concerned chapters in the lecture notes: 1 - Side spillways (Chap. VII - Simplified models and characteristic flows - Water lines in the case of side spillways) Computation of the waterline in a channel at the location of a side spillway - Case study of a retention basin with a pouring crest. 2 - Characteristics theory (Chap. X - Introduction to unsteady hydrodynamics - Fundamental properties of the models in free surface hydrodynamics - Transformation under characteristics form in 1D, general use of the characteristics theory ) Computation of an hydrogram propagation in a Meuse river reach using the characteristics theory - Application to the optimisation of the working of a cascade of hydroelectric power station along a river - Discussion about the multi-criteria management of hydrographic networks - Discussion about the management of the Meuse river. 3 - General calculation of the waterlines for any regime (Chap. X, XI & XII - Fundamental properties of the models in free surface hydrodynamics - Stability analysis and temporal discretization - Spatial discretization of the equations - System conservative or not, linear or not, theoretical solution of the linear system, numerical solution of the discretized linear system, discretization by finite differences...) Writing of a numerical solver for the general calculation of the waterlines in the VBA environment of Excel (Visual Basic) - Tests of different practical cases and boundary conditions: saw-teeth like bottom, sluice gate, 3 slopes Discussion about the modern view of hydrodynamics mixing continuous and non-continuous phenomena. 4 - Numerical resolution of the cinematic wave equation Writing of a numerical solver for the cinematic wave equation - Tests of different practical cases and boundary conditions - Study of the influence of the time step value, the discretization scheme Highlighting of the non-liner nature of the runoff - Discussion about the impacts of short and intense rains - Effects of the climate change. | |||||

| Course objective : | This class fits directly into the continuity of the class Applied hydraulics I by treating the unsteady part of the free surface flows and by paying particular attention to the methods for global management of hydrographic catchments. In addition to ex-cathedra lectures supplying the essential theory and basic equations, practical reflexion works, based on real-cases, allowed the use of modern resources for the resolution of problems classically met in the field of free surface flows unsteady hydraulics.Attractive and exhaustive lecture notes judiciously completed the informations given during lectures, and a forum of questions allowed a quickly and easy contact between teacher and students (http://www.ulg.ac.be/hach). | |||||
| ||||||
| Organization : | The class is given during second semester on Monday and Thursday afternoon for 8 weeks | |||||
| ||||||
| Written notes : | Comprehensive typing out lecture notes (814 pages) available. | |||||
| ||||||
| Assessment : | Each practical work report provides an individual appreciation.An oral evaluation for the whole lecture is scheduled during June or September examination session. It is made up of theoretical and application questions.Final mark is obtained by weighted mixing of the partial appreciations. | |||||
