The Drainage Runoff Library command allows you to store commonly used drainage area types and their runoff coefficients. The library file is in the ...\USER folder and is available for all projects in sewer network design.
From the Network > Sewer Network Libraries menu in the Hydrology Module, select Drainage Runoff Library to open the library dialog. The Type of Drainage Area list displays all the stored drainage area types and the Runoff Coefficient list displays the corresponding runoff coefficients. New button creates a new drainage runoff entry, Edit button allows you to modify the highlighted entry, and Delete button removes the highlighted entry from the library. Load and SaveAs buttons allow you to load and save the library data.
