### 講義計画

Guidance 1 The contents of this subject are introduced, overviewing the whole framework of Open Channel Hydraulics with various theoretical and computational results.
Derivation of 2-D depth averaged model 1 Derivation procesures of the plane 2-D depth averaged flow model are expalined in detail.
Application of singular point theory to water surface profile analysis 1 The application of singular point theory to water surface profile analysis is explained.
1-D analysis of unsteady open channel flows 3 Fundamental characteristics of 1-D unsteady open channel flows, Method of Characteristics, Dam break flows, Computational methods for shallow water equations
Fundamentals of numerical simulation 1 Considering the convective equation as a basic example, the fundamental knowledge of numerical simulation is explained by means of finite difference method, finite element method, etc. Applications of these method to unsteady open channel flow equations are also shown with some practical applications.
Plane 2-D analysis of steady high velocity flows 1 Characteristics of steady plane 2-D flows are explained based on the method of characteristics.
Plance 2-D analysis of unsteady flows 3 Propagation of characteristic furface, shear layer instability, application of a generalized curvilinear coordinate to river flow computation, application of a moving coordinate system, etc.
Higher order theory 3 Boussinesq equation with the effect of vertical acceleration, mixed flows with pressurized flows and free surface flows observed in a sewer network system, trafic flow analysis by means of dynamic wave model
Achievement Confirmation 1 Understanding of the contents on Open CHannel Hydraulics is confirmed.
