I am modeling several sub areas and ponds. Does the pond surface area need to be added to the sub area size? Or, does hydrocad recognize the pond surface area when a pond node is added to the model? If hydrocad recognizes the pond surface area when a pond node is added, what curve number is being used in the runoff calculations?

Example:
Sub Area Size = 5 acres
Pond Surface Area = 1 acres

Do I add my sub area size at 6 acres with a weighted curve number, or do I add a sub area node @ 5 acres with appropriate curve number and a pond node with stage storage table?

Thanks in advance
