  9. Rational Method RATIONAL MODEL FOR COMPUTING Q PEAK DISCHARGE FROM A WATERSHED OR SUBBASIN Where Q = Peak discharge in cubic feet. Per second A = Area of the watershed in acres C = Coefficient of runoff for the watershed, based on area-proportional, combined runoff coefficients for slop, land cover and soil types T = Concentration time (in minutes) I = Maximum rainfall intensity (in inches per hour) that can occur during the concentration time M = Mannings’s coefficient of roughness Q = f ( A, C, T, I, M )

  10. Low-Impact Residential Development Concept for a Suburban Sub-basin

  11. LID Site Conservation Porous Pavement Reduced Imperviousness Amended Soils Open Drainage Rain Barrel Rain Gardens Create a Hydrologically Functional Lot
