Purpose and Background
Detention ponds are designed to provide numerous functions, including reducing peak discharges and improving water quality. Improperly designed, they can be a hazard to the public. This online course will provide you with the information needed to design an appropriately sized detention pond that will provide numerous benefits and limit liabilities. Topics covered include: rainfall data sources, rainfall runoff modeling, inlet grate capacity analysis, outlet capacity design and analysis, detention pond sizing and underground ponds, routing a hydrograph through a detention pond, impacts of ponds on water quality and hazards of detention ponds and when not to use them.
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
