reservoirsplitsingen

Reservoirsplitsingen is a concept in water resources engineering describing the strategic partitioning of a reservoir’s live storage into distinct functional compartments during operation. The aim is to influence hydraulic mixing, contaminant transport, sedimentation, and the sequencing of water releases by creating zones that can be operated semi-independently under a centralized control system. In practice, reservoirs can be partitioned using a combination of movable barrier elements, adjustable gates, and controlled inflow routing, coordinated by real-time monitoring and optimization algorithms.

The term appears to be a product of recent interdisciplinary discussions among hydrologists, civil engineers, and water managers, and is not yet standard terminology in most guidelines. It has been proposed in pilot studies and modeling exercises as a means to improve flood management, drought resilience, and water quality, particularly in multi-purpose reservoirs and systems with variable inflows.

Typical applications include reducing the spread of high-salinity inflows into fresh storage, isolating sediment-rich inflows to limit turbidity, enabling targeted releases during drought or high-demand periods, and allowing more flexible management of simultaneously competing water uses.

Benefits of reservoir splitting can include finer control over timing and quality of releases, improved sediment management, and enhanced system adaptability. Limitations include higher capital and operating costs, increased operational complexity, potential ecological impacts from altered mixing patterns, and the need for robust monitoring and maintenance.

In related fields, reservoir splitting intersects with dam safety, multi-reservoir optimization, and adaptive water resources management.
