Drainage 6.1

This program will allow the Engineers or Contractors to perform a quick estimate of the required drainage facilities for small construction projects.
The program consists of four parts. The first function is the Runoff calculator. The user uses this function to estimate the amount of runoff in the area of concern. From this output the user knows the flow capacity of runoff that he has to deal with.

Next the user can access the Channel capacity calculator. Knowing his required flow capacity, the user can now design his drainage ditches.

Most projects must use culverts to divert the flow under roads or other obstructions. The Culvert capacity calculator can be used to size either round or box culverts.

Finally, the project may involve some road construction, which requires curb drains. The Inlet capacity calculator will tell the user the capacity of his storm drains.
