Part I (theory, writing test):

1) Cont= inuity equation, 2) Momentum equation.
- · Applicati= ons of HEC-RAS for unsteady flow problems
  - = 1)      Specify unsteady boundary conditions, such as
    
    Upstream time series of fl= ow,
    
    Down stream time series wa= ter elevation, etc
    
            =       2). View model out put to show flood area.
    
            =       3). Design/modify hydraulic design to reduce flood area.
