I need help trying to explain to lay people that a much larger open channel ditch that may hold water, mosiquito breeding ground, have weeds, bank erosion (i.e. maintenance headache) that outfalls into a canal, that has a water surface elevation sometimes 3 feet higher than the invert of the ditch, is compared to a smaller smooth closed pipe that has a consistent slope.
The idea of the greater difference in surface area between the two confuses people to think that the ditch can handle more flow.
Bare in mind, I am working for a developer of a property adjacent to an existing subdivision that drains into the ditches that we will be inclosing. (Don't develop in my backyard syndrome)
Another thing to bare in mind is dentention is not an option. I live in New Orleans. We are below Sea Level. We pump water out not hold it in.
Any ideas on visual presentations that can convince the existing residents that a closed system will be better for them.
Thanks...in advance.
