St. Lawrence University
IN-15: Stormwater Modeling
|0.50 / 0.50|
A brief description of the institution’s stormwater modeling program and/or practices, including the methodologies and tools used:
The University uses the USDA-NRCS Technical Release 55 (TR-55) –Hydrology for Small Watersheds model. This model is widely used for stormwater hydrology and features full hydrograph development using TR-20 computational engine, capability to change the rainfall distribution and the dimensionless unit hydrograph, Muskingum-Cunge channel routing, updated reservoir routing procedure, and graphical hydrograph output. The University uses the TR-55 in conjunction with the USEPAs stormwater calculator to plan and to assess the impact(s) of green infrastructure.
For which of the following percentile local or regional rainfall events does the institution retain runoff on-site using LID practices and green infrastructure? (95th, 90th, 85th, 80th, 75th, Other):
The percentile local or regional rainfall event for which the institution retains runoff on-site using LID practices and green infrastructure (0-100):
