What is the best way to model a pond that has a spillway (weir) that operates separately from (in parallel with) another outlet structure such as…
I'm trying to model a composite outlet structure that has an orifice and a riser with a grate that acts as a relief for larger than designed storm events. I also want to include an emergency spillway that is offset from the structure itself and is simply…

I understand the difference between incremental and cumulative when it comes to inputting storm data into PondPack, but I need a better understanding of why I get different peak flows when using cumulative. What does PondPack do differently for the calculation…

I've been tasked with modeling this outlet control structure using PondPack. I've run into two problems:
1.) modeling the T-shaped weir near the top of the wall without double-counting the flow of the initial 1' wide weir section. Modeling the shape…

I have tried to replicate the calculations using the standard weir equation [Q = CLH^(3/2)], but have since realized that PondPack must be applying an additional factor to the calculation that is based on the head, because the factor varies as the head…

I am designing a sand filter/pond in PondPack (CONNECT edition) which needs two outlet structures in order to split the outflow from the pond to two different outfalls. The outflow needs to be split in order to meet pre-development flow requirements.…

We're using PondPack to design a bioretention basin with an perforated underdrain pipe. How should we go about modeling this in the software?

I am trying to understand what calculations PondPack uses when you set culverts as a Downstream ID. I created a model that is utilizing culverts as the main outfall which will discharge directly upstream of a culvert crossing. I have the pond outfall…
I am looking to insert the below precipitation data for the 2, 25 and 100 year storms into PondPack as provided by the AHJ. This specific data set has a varying timestep which does not align with the standard storm event input. Can you please assist me…
