Weboped a slope-adjusted CN equation (equation 1) as follows: (1)...where CN 2 is SCS handbook CN value, CN 2α is adjusted CN for a given slope, and α is slope (m·m-1) between 0.14 and 1.4 (14-140%). This equation appears to be the most appropriate for runoff prediction in the steep areas [4]. Many researchers [2, 7-9] have utilized the standard CN WebHydroCAD@ 10.00-21 10255 ©2024 HydroCAD Software Solutions LLC Type 11 24-hr 1-yr Printed 8/24/2024 Paqe 3 Inflow Area = Inflow Outflow Primary Summary for Pond 2P: G4ConveyanceSwale 0.800 ac, 12.50% Impervious, Inflow Depth > 0.68" for 1-yr event 0.86 cfs@ 11.99 hrs, Volume= 0.03 cfs@ 15.25 hrs, Volume= 0.03 cfs@ 15.25 hrs, Volume= … WebHydroCAD® 10.00-20 s/n 06129 © 2024 HydroCAD Software Solutions LLC Page 9 Summary for Subcatchment 5S: Lots 12, 14, 15, 16, 17 Existing Runoff = 7.31 cfs @ 12.36 … how old is simone young
