Good day everyone!
I'm currently reviewing a plan that involves the above-mentioned subject. It's a drainage/interceptor connected to a creek upstream and a detention pond downstream. The structure involved originally was a 400m (sta. 0+000 to Sta. 0+400) double barrel box culvert below the alignment of a road with man hole structures every 20m. Due to construction problems, the design was proposed for revision wherein along sta. 0+200 to sta. 0+260, the box culvert will be replaced with a circular steel pipe.
Is there a manual or guidelines in determining equivalent size or diameter of pipes using the design discharge calculated from the previous design? What other critical analysis are required for such changes? Thank you in advance.
