BMPTRAINS MODEL: BACKGROUND INFORMATION ON SWALES BY: MARTY WANIELISTA, PHD., P.E.
METHODOLOGIES SWALES From Avellaneda, Eduardo. 1985. M.S. Thesis, UCF EXFILTRATION TRENCH RETENTION BASIN WET DETENTION STORMWATER HARVESTING FILTRATION including BIOFILTRATION PERVIOUS PAVEMENT RAINWATER HARVESTING FLOATING ISLANDS WITH WET DETENTION GREENROOF VEGETATED NATURAL BUFFER VEGETATED FILTER STRIP TREE WELL RAIN (BIO) GARDEN SWALE USER DEFINED BMP RAIN (BIO) GARDEN SWALE USER DEFINED BMP
GRAPH TO AID IN SPACING 80% Capture 5% slope Downstream Upstream
HYDROGRAPH WITH SWALE BLOCK Mass balance average infiltration rate about 5 inches/hour
SWALE WITHOUT SWALE BLOCK Mass balance average infiltration rate about 2 inches/hour
PROGRAMMING OF EQUATIONS ( AN EXAMPLE)
EXAMPLE OUTPUT SWALE DESIGN REQUIRED REMAINING TREATMENT EFFICIENCIES OF TREATMENT SYSTEM IN SERIES WITH SWALE. USE FOR SIZING OF TREATMENT SYSTEM IN SERIES WITH SWALE. 69.346 % 69.346 % Remaining treatment efficiency needed (Nitrogen): Required pre-treatment efficiency (Phosphorus):
