This course is for Civil engineers, who might be interested or involved in stormwater runoff. One of the initial requirements in the design of culvert, channels, detention ponds, outlet structures and storm sewers is an estimate of the peak stormwater runoff. This course covers three methods of an estimate of peak stormwater runoff. The uses of some computer programs are mentioned.
