Reservoir Initial Condition
Overview
HYDRO requires a water surface initial condition at reservoirs. The Reservoir IC view allows the user to specify default initial conditions. The default initial condition is required but will be overridden if a restart file is used.

# Description:
# Initial Condition of Clifton Court Forebay

The RESERVOIR_IC table specifies initial water surface elevations for reservoirs.
Field Descriptions
- RES_NAME: Name of the reservoir where the initial condition is to be applied.
- STAGE: Initial water surface elevation.
Table Info
- Identifier: NAME
- Include Block: INITIAL_CONDITION
Default initial values are replaced if a restart file is used. Consistency should be maintained between initial reservoir-channel stage differences and flows at nodes. If the reservoir is assigned a different initial stage than surrounding channels, the head difference implies a flow described by the reservoir equations. Unless carefully balanced, the initial time step may have a mass imbalance. To avoid this, set the reservoir stage equal to surrounding channels and make the initial flow zero.
