Delineate Watershed for Roadway

[@hussainmustafashahzad4189]

Is there more detailed video for identifying locations of culverts , swales etc

I do not have a more specific video on this topic but can see why it would be helpful. In general, this is subjective to the engineer and placing culverts is not an exact science.

@@kennethwlamb is it possible for you to show how to determine flood levels so that structures are placed safe levels, like 10 year ARI flood level will have what depth so that construction contours can be created ?

@@hussainmustafashahzad4189 That is a good suggestion for the next video. That kind of analysis is best completed in software like HEC-RAS, or HEC-GeorRas (www.hec.usace.army.mil/software/hec-georas/). However, there are some ways to map the results by sketching directly on the map.
