Estimating Stormwater Runoff
In Estimating Stormwater Runoff, you'll learn ...
- How to use three different methods to determine peak stormwater discharge
- How to use an I-D-F chart
- How to determine the time of concentration from
- How to determine the CN number based on soil type, cover and land use
Overview
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.
