I have a site that has a topographical high point in the center which drains into two separate drainage areas (wetland drainage ditches/swales). The drainage areas are paralel to each other and run straight through the site.
My question is, how detailed does the routing diagram need to be? I delineated the drainage area in a great amount of detail on the topo map, however, I would end up with close to 40 nodes to define each drainage pattern. Do I need a node for every change in slope? Part of my problem is that the drainage area (or valley) receives drainage along the entire length of the site - do I need to stress about the channel length when the channel is receiving runoff along the entire length?
Any information or advice is greatly appreciated. I am not a civil engineer and have little experience with this level of detail with the modeling and just want to get a reality check.
I have gone through the tutorial and manual and can not find any clear guidance on this topic.
Thank you in advance.
