CHANL and MCHANL (metric version) are computer programs which reduce and analyze stream channel cross-section survey data collected by either a rod and level survey or a sag tape survey. Data may be entered from the keyboard or a file. Cross sections are plotted on x-y coordinates and discharge rating curves are developed using Manning's equation given a user-supplied value for Manning's "n". Output tables include values for average flow velocity (for each discharge increment), cross-section area, wetted perimeter, and hydraulic radius. Access CHANL or MCHANL on the BLM Honeywell DPS-8 by typing A403/CHANL or A403/MCHANL.
