My company uses alot of perforated pvc pipe in a stone trench, as an underdrain in alot of our projects. As the recent graduate from University I have been tasked with learning SSA and how to model some of our more complex designs. I seem to have a handle on most of the software except for how to model this piece of pipe.
I am just wonder what is the best way to model these in SSA, as they are both storage and inlets.
Thank you for your help.
Solved! Go to Solution.
How about the case for an 'Enhanced Water Quality Swale', where the stored water needs to infiltrate through an engineered sand filter to an underdrain connected to the rest of a storm drain system. Because of the prescribed infiltration rate (1.5in/hr) of the sand material (30" deep), there is a substantial delay between the time the first drop hits the swale to the time the first drop reaches the underdrain. I've been at a complete loss to figure out how I can get SSA to model this properly.
Was this ever resolved? I am in the same situation. I am trying to model stormwater sanfilter that has sand media and a perforated underdrain pipe beneath it. I have no clue how to model it in SSA. Any suggestions Autodesk?
