What is the correct term for snowmelt drainage systems?

The correct term for snowmelt drainage systems is stormwater drainage. This term encompasses the management of surface water that results from precipitation, including both rain and melting snow. Stormwater drainage systems are designed to prevent flooding and manage water quality by directing the flow of excess water away from populated areas and into appropriate drainage channels or retention basins.

Snowmelt creates a significant volume of water that can lead to runoff issues, similar to rainwater, hence the inclusion within the broader category of stormwater management. Effective stormwater drainage systems are essential in areas that experience significant snowfall, ensuring that water is properly channeled to prevent property damage and environmental impacts.

The other choices do not capture the comprehensive nature of how snowmelt is managed in conjunction with rainfall within established drainage systems. Snow runoff systems is a more limited term that focuses specifically on snow, while surface water management and rainwater collection systems refer to broader and more specific practices that do not directly address the dual challenges posed by snowmelt and rainfall.
