Course Outline
This 3 hour course Peak Rates of Runoff from Small Watersheds will cover various characteristics of the watershed that influence peak rates of runoff. Several design examples will be given in the text to help aid the student in understanding the course material.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
Learning Objective
At the conclusion of this course, the student would have learned the following:
- Likely cause of variation of peak rates in watersheds;
- Effects of physiographic characteristics on watersheds;
- How to define the precipitation index;
- How to calculate the recurrence interval;
- How to calculate the probability of exceedance;
- How to determine the drainage density;
- The relationship between Area, precipitation index and drainage density; and
- How to determine the average occurrence, etc.
Intended Audience
This course is intended for hydrologists, storm water engineers, civil site designers, roadway designers, contractors, municipal engineers, project managers, and any persons working in the civil engineering field or anyone with an interest in peak rates of runoff from small watersheds.
Benefit to Attendees
This course will cover Peak Rates of Runoff from Small Watershedss.
Course Introduction
In preparing their hydrology calculations, engineers and hydrologists often have to make a determination of the peak runoff from small watersheds. Various formulas and calculations are often used to determine the runoff from small watersheds. It has been found that watersheds with the same areas have wide variations even with similar physiographic characteristics.

The following formula would be useful in determining the Probability Pe that an event will be equated or exceeded at least once per period, as shown in Table 8 of the text.
Pe = 1-[1-(1/T)]n
Where T is the average recurrence interval in years and n is the number of years.
The information presented in this course will provide the reader with the knowledge that will aid in the preparation of hydrology studies and storm water pollution prevention plans.
Using good engineering judgment is always paramount in any situation. Utilizing good judgment and the knowledge gained in this course will aid the reader with the knowledge to be successful in determining peak rates of runoff from small watersheds.
