The TR-55 parameters dialog is accessed by right-clicking on a basin or outlet then selecting the Edit Paremeters command. The dialog allows setting model parameters for either "Basins" or "Outlets" depending which option is selected at the top of the dialog. Parameters can be set for the "Selected" basin or outlet, or for "All" basins or outlets based on the selected option at the top of the dialog.
Options available include:
Basins
- Basin Name – Enter the desired name for the basin.
- Time of Concentration (TC)(hr)
- Compute Tc – Basin Data – Opens the Basin Time Computation dialog.
- Compute Tc – Map Data
- Drainage Area (Am)(mi^2)
- Rainfall (P)(in)
- Runoff Curve Number (CN)
- Pond and Swamp Area (%)
- Rainfall Distribution
- Unit Peak Discharge Computation Method
- Potential Maximum Retention (S)(in)
- Runoff (Q)(in)
- Initial Abstraction (Ia)(in)
- Initial Abstraction / Rainfall (Ia/P)
- Unit Peak Discharge (Qu)(cfs/mi^2/in)
- Pond and Swamp Factor (Fp)
- Peak Discharge (Qp=Qu*Am*Q*Fp)(csf)
- Compute Hydrograph
Outlets
- Outlet Name – Enter the desired name for the outlet.
- Travel Time (hr)
- Compute Travel Time
- Compute Hydrograph
