Stormwater Management
The planning, design, and implementation of systems to control the quantity and quality of rainwater runoff in urban and developed areas, reducing flooding and water pollution.
Water & ResourcesStormwater management refers to the strategies and infrastructure used to handle rainwater runoff from impervious surfaces such as roads, rooftops, and parking areas. Unmanaged stormwater can cause flooding, erosion, and the transport of pollutants into rivers, lakes, and groundwater.
Approaches
- Grey infrastructure: Traditional engineered systems including storm drains, retention basins, and underground storage tanks.
- Green infrastructure: Nature-based solutions such as bioswales, rain gardens, permeable pavements, green roofs, and constructed wetlands.
- Low Impact Development (LID): A design philosophy that mimics natural hydrology by managing rainfall close to where it falls.
Why It Matters
Urbanization increases impervious surface area, amplifying runoff volumes and peak flows. Climate change is intensifying rainfall events in many regions, making effective stormwater management critical for protecting communities, ecosystems, and water quality.
Career Relevance
Stormwater management employs civil engineers, urban planners, hydrologists, landscape architects, and environmental consultants. Municipalities, engineering firms, and water utilities hire professionals who can design compliant drainage systems, model runoff scenarios, and implement green infrastructure projects.
