What are the main types of stormwater design?

• A. Surface system and underground system
• B. Temporary storage systems and permanent storage systems
• C. Open systems, closed systems, and combination systems
• D. Residential systems and neighborhood systems

Answer: (C)

The classification of stormwater design into open systems, closed systems, and combination systems is particularly important because it reflects the various ways that stormwater can be managed, conveyed, and treated as it flows through the landscape. Open systems typically refer to designs that use natural or constructed ditches, channels, and swales that allow stormwater to flow freely while providing opportunities for infiltration and natural filtration. These systems help to manage runoff while mimicking natural hydrological processes, reducing flooding and improving water quality. Closed systems, on the other hand, involve the use of pipes and underground conduits to transport stormwater away from areas of development. This system is often used in urban settings where space is limited and surface flow might lead to flooding or infrastructure damage. Closed systems can effectively manage large volumes of runoff, but they may require more careful consideration of treatment options before the water is discharged into natural bodies. Combination systems incorporate elements of both open and closed systems, allowing for flexible and efficient stormwater management. They can utilize surface flows in certain areas while employing underground systems in others, leading to more sustainable outcomes by managing the stormwater according to the specific conditions and needs of the site. Understanding the differences between these system types is essential for effective stormwater management and
