Urban Runoff and Stormwater Management

Urban Runoff and Stormwater Management Training Course Description

The urban runoff and stormwater management training course introduces you to the basic principals of stormwater Best Management Practices (BMPs).

Stormwater management tackles two categories of hydrology and ecology. In the urban runoff and stormwater management training course, we help you identify both hydrological and ecological issues associated with stormwater and train you to manage them.

In general, stormwater management is defined as managing the surface runoff. Therefore, it can be used for both rural and urban runoff applications. However, the urban runoff and stormwater management training course is focused only on the urban runoff because the stormwater cannot infiltrate the impermeable surfaces of the city streets and thus more critical to be controlled and monitored.

In contrary to the conventional stormwater management methods, in which high peak flows were drained away, in the modern management practices we rebuild the natural water cycle by storing the runoff water in retention basins, recharging groundwater through infiltration basins, or using the collected water as non-potable water supplies. Through the urban runoff and stormwater management training course, you gain knowledge about planning, implementation, operation, and maintenance of such methods.

The urban runoff and stormwater management training course teaches you to study the geological elements of the site you are going to design a BMP for and then based on the location, the potential pollution sources, the stormwater flow rate, and the budget of the project, you can choose and design the most suited method.

 Audience

The urban runoff and stormwater management training is a 2-day course suitable for engineers, scientists, and managers are or will be involved with designing methods and approaches to manage the stormwater in cities.
