Flow diagram a simplified sketch that uses symbols to identify instruments and vessels and to describe the primary flow path through a unit Foundation drawings concrete wire mesh and steel specifications that identify width depth and thickness of footings support beams and foundation Process flow diagrams should include the information regarding the connection between various systems It also consists of the process piping and major parts details Process flow diagrams are usually drawn on a large sheet of paper Nowadays with the advent of computers and new technology we tend to use computerized process flow diagrams culverts to pass the 100year flow 3 Bottomless culverts with footings should be designed to pass the 100year flow with the headwater less than the top of the culvert The 25year should allow 1 foot of freeboard for debris flow 4 Headwater to culvert diameter HWD should be less than or equal to 125 though it can be up to 3 to 5 if
