The practice and opportunities in re-operating dams for the environment

For most of the 20th century, the design and operation of dams prioritized traditional economic considerations such as hydropower generation, flood risk reduction and provision of water for irrigation and domestic use. This resulted in altered river flow regimes, degraded riverine ecosystems and ecosystem services, and biodiversity loss....

Pwalugu Multipurpose Dam: Beneficial for Local Communities too?: A System Dynamics perspective on the costs and benefits of the construction and operation of the Pwalugu Multipurpose Dam on local and national levels

Modelling both local and national effects of construction and operation of the Pwalugu Multipurpose Dam

Re-operating dams for environmental flows: From recommendation to practice

Dam construction and operation are known to alter the hydrology of rivers and degrade riverine ecosystems. In recent decades, the call to reverse these negative impacts by re-operating dams has become stronger. Dams can support riverine ecosystems by releasing environmental flows (e-flows). Unfortunately, despite the development of numerous...

Long-term effects of dam operations for water supply to irrigation on downstream river reaches. The case of the Ribb River, Ethiopia

This work investigates the applicability of an analytical method for quick assessments of the long-term morphological effects of different dam operations on downstream river reaches with the idea to apply the method in feasibility studies to identify the least morphologic-impacting operation scenario. The Ribb River (Ethiopia) is used as a...
