Programma e contenuti
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)
