DEPARTMENT OF CIVIL ENGINEERING AND ARCHITECTURE
1st semester (27/09/2021 - 21/01/2022)
48 lesson hours
The Course of deals with theoretical and application matters chiefly referred to the Teaching Fields of : Hydraulic and Fluid Mechanics .It is useful for the students a preliminary frequency of the teaching Matters above mentioned, for an easier understanding of the object of the Course
Give the concepts necessary to use one and two dimensional unsteady flood propagtion models. The last part of the course is dedicated to the use of ORSADEM software
Introduction: steady and unsteady flow, uniform and varied flow, pipe flow vs open channel flow
De Sant Venant equations (1d), divergent and non divergent form, supplementary terms and coefficients
Initial and boundary conditions
Discontinuous solutions: Bores
Simple wave, Dam break waves
Italian Regulations on Dam safety
Simplified channel flow equations
Numerical solution of the unsteady flow equations (method of characteristics, explicit and implicit
finite differences methods, numerical integration schemes: predictor corrector, flux splitting,
upwind and downwind; accuracy of the numerical method, stability analysis
Shallow water equations (2D)
Mesh generation (structured/non structured)
Simulation of flow in natural streams (1d vs 2D models, topological and hydraulic discretization,
some computational problems in rivers and floodplains, flooded area mapping techniques)
Models calibration and data needs
Flood wave propagation through hydraulic singularities
Introduction to the use of ORSADEM code
Case study: analysis of Sella Zerbino dam break (Italy)
