Drainage Designv5.0 Description:
The program consists of four functions. The first function, the Runoff Calculator, lets you estimate the amount of runoff (flow capacity) in the area of concern.
The second function, the Channel Capacity Calculator, enables you to design the drainage ditches.
The third function, the Culvert Capacity Calculator allows you to size either round or box culverts to divert the flow under roads or other obstructions.
Finally, the fourth function, the Inlet Capacity Calculator, lets you estimate the capacity of the storm drains.
Please note that you can only process US units.
