Överflödesmagasins

Överflödesmagasins, often translated as overflow magazines or storage basins, are structures designed to temporarily store excess water during periods of high flow in drainage systems or natural watercourses. Their primary purpose is to mitigate the risk of flooding downstream by holding back a volume of water that would otherwise overwhelm the capacity of the receiving channel or infrastructure.

These structures are typically integrated into the design of stormwater management systems, canals, or river embankments. They can take various forms, from engineered concrete basins to natural depressions or expanded sections of a waterway. The design of an överflödesmagasin considers factors such as the expected peak flow rates, the desired storage volume, and the method of controlled release of the stored water once the flow in the main system recedes.

The operation of an överflödesmagasin is usually passive. When water levels rise beyond a certain threshold, excess water naturally flows into the magazins. As the water level in the main system drops, the stored water is gradually released back into the system through controlled outlets or sluice gates, or it may be allowed to infiltrate into the ground, depending on the specific design and environmental considerations. Överflödesmagasins are a crucial component in urban planning and water resource management to protect communities and ecosystems from the damaging effects of floods.
