Reguleringsmagasin

Reguleringsmagasin is a term used in civil engineering and hydrology to describe a storage facility that regulates the flow of water in a river or canal system. The facility typically functions as a reservoir, often located behind a dam or within an artificial basin, where water can be stored during periods of high inflow and released during periods of low inflow to smooth discharge and meet downstream needs.

The primary purposes of a reguleringsmagasin include securing a reliable water supply, enabling hydropower generation, reducing flood risk, and stabilizing water availability for agriculture, industry, or municipal use. In many river regulation schemes, reguleringsmagasiner are coordinated with other reservoirs to optimize overall water resources management across a region. A reguleringsmagasin usually comprises a basin or reservoir, intake and outlet works, gates or valves, spillways, and related control equipment, and it may be part of a pumped-storage system in which water is moved between elevations to store or release energy.

Operations are guided by water management plans, weather forecasts, demand patterns, and flood-forecast information. Environmental considerations include maintaining ecological flow requirements, sediment transport, and minimizing impacts on aquatic habitats; mitigation measures such as environmental flows, fish passage, and sediment management may be incorporated.

Etymology: the word combines regulering (regulation) and magasin (storehouse, reservoir) in Danish and related Scandinavian languages. See also: dam, reservoir, flood control, water resources management.
