Summary: Rivers in tropical climates have highly variable flows that are becoming even more unstable due to climate change. This study focuses on selecting and sizing a hydropower plant for highly variable flows using the Sebeya River as a case study. The study uses machine learning to predict the river flow and stochastic modeling to estimate energy generation and cost for different turbine types.

Summary: Giving full play to the flexibility of hydropower and integrating more variable renewable energy is of great significance for accelerating the transformation of China's power energy system. This study proposes a novel day-ahead scheduling model that considers the flexibility limited by irregular vibration zones (VZs) and the probability of flexibility shortage in a hydropower-variable renewable energy hybrid generation system. The model is applied to a real hydropower station and effectively improves the flexibility supply capacity of hydropower, especially during heavy load demand in flood season.

Summary: This paper presents a hierarchical framework that connects hydrologic and economic modules to assess the economic repercussions of strengthening irrigation quotas to achieve minimum environmental flows. Results show that reductions in agricultural water allocations lead to incremental profit and employment losses in irrigated agriculture, particularly during extreme droughts.

Summary: The study evaluated the non-uniformity of intra-annual runoff distribution (IARD) in the Datong River basin (DRB) and constructed an optimal operation model for cascade hydropower plants (CHP) based on this. It was found that as runoff decreased and non-uniformity increased, the energy generation of CHP showed a decreasing trend, and the impact of non-uniformity of IARD on energy generation would be greater with increasing inflow.

Summary: Water scarcity and degradation of water quality are significant challenges faced by many basins globally, particularly in arid and semiarid regions. Agriculture plays a key role in depleting and polluting water resources, as well as contributing to greenhouse gas emissions. Effective policies can mitigate the impacts of climate change, enhance water quality, and reduce greenhouse gas emissions, improving social welfare.

Summary: Climate change is posing challenges for water systems planning, and an integrative methodology is proposed to define adaptation strategies at basin scale. The methodology combines both impact-oriented top-down approaches and vulnerability-oriented bottom-up approaches. The approach was applied to the Jucar basin, and the results showed significant variability of climate change impacts across the basin. Stakeholders prioritized adaptation options such as drip irrigation, use of non-conventional resources, and changes in water governance.

Summary: The impacts of dams on aquatic organisms are not limited to local river sections but extend to entire river basins. Dams have significant effects on traits such as maximum body size, functional feeding groups, voltinism, and occurrence in drift of macroinvertebrates. Changes in water nutrients and habitat quality induced by dams play a crucial role in shaping trait structure. This study highlights the usefulness of a trait-based approach for assessing dam impacts and emphasizes the importance of spatial scale in studying the effects of dams on riverine systems.

Summary: Based on household survey data from China's upper Red River Basin, the construction of small hydropower plants may have negative impacts on river systems, such as affecting irrigation water supply, provoking changes in agricultural practices, and negatively impacting river health. Villages with strong local governance can negotiate with hydropower plants to temporarily halt generation in order to mitigate social impacts.

Summary: Increasing environmental restrictions pose challenges to the operational flexibility of hydropower plants. This paper proposes a Mixed Integer Linear Programming algorithm for short-term regulation of hydropower plants with energy storage. The algorithm is used to analyze the techno-economic feasibility of three hydropower plants in Sweden. Results show that current battery costs make the short-term regulation with the combined hydropower plant and battery system not profitable, indicating the need for lower battery costs.

Summary: Limited water availability, population growth, and climate change have led to freshwater crises in many countries, with Jordan facing a particularly severe situation exacerbated by conflict-induced population shocks. A comprehensive Jordan Water Model has been developed to assess the nation's freshwater security under climate and socioeconomic changes, revealing significant declines in water security without intervention. Implementing large-scale desalinization and comprehensive water sector reform could lead to exponential improvements in water security for Jordan's future.

Summary: Flow regulation through dams increases water and energy security for society but also threatens the natural equilibrium of river basins, leaving ecosystems and communities more vulnerable. To guide the design of environmental flows and support improved ecosystem restoration, a methodology framework is proposed that builds an ensemble of flow regime options based on the naturalized flow regime range variability and quantifies the ecosystem response of each option in terms of migratory fish abundance with an artificial neural network model.

Summary: Climate change can have negative impacts on water systems, and it is important to develop adaptation strategies. This study proposes a hydrologically-driven approach to support the reoperation of multipurpose multireservoir systems. By using climate models to drive a climate stress test and clustering hydrologic projections based on relevant attributes, adaptation measures can be identified. The case study in the Lievre River basin in Quebec, Canada demonstrates that cluster-specific operating rules can improve system performance and showcase operational flexibility.

Summary: The impacts of climate and land-use changes have rendered the stationary assumption in hydrology obsolete, leading to considerable uncertainty regarding future climate evolution. Assessing the robustness of hydrological models across a wide range of climates is crucial, as shown by using a hidden Markov model to identify diverse hydrologic sequences in the upper Senegal River basin. This approach provides valuable insights for evaluating the performance of hydrologic models under different climate conditions.
