I have a small site, less than 5 acres. I need to calculate pre-post project stormwater calcs.
My plan is to use rational equation and use NOAA Atlas 14 for precipitation intensity (I) in the equation. Looking...
I am modeling a pond, and my outlet structure is an inline weir, but it has a bridge across the top. Should this be done with a custom weir defining the rectangular opening and use the weir coefficient for the broad crested weir? Not sure if there is a more appropriate way to define this in...
I have an existing pond with a riser primary spillway and earthen emergency spillway.
For the current conditions, the primary and emergency spillway were defined using a rating curve. I am working on a redesign of these spillways to pass certain rainfall events, and did not choose to define...
