Flood Management & Rainwater Harvesting on Road

Soil surface in urban areas becomes covered by impervious materials, such as asphalt and concrete, the natural water cycle is disrupted due to rapid urbanization. When landscape architects finish landscaping wetlands, they can no longer allow water to seep into the soil. This causes surface runoff, flooding in urban areas, traffic disturbances, and low groundwater levels. The current project about flood control includes system and roadside rain water harvesting. The rainwater is collected and filtered through drain and sand filter mechanisms and is stored in a tank. The experiment was carried out to analyze the flow rate, filtration efficiency and backwash performance. It can be concluded from the results that the model is useful for surface runoff, groundwater recharge and sustainable stormwater management in urban areas.
