“…Several studies have been documented assessing trade-offs between reservoir releases for downstream ecosystems and for other uses (Jager and Smith, 2008), including hydropower in particular (e.g., Harpman, 1999;Jager and Bevelhimer, 2007;Beilfuss, 2010). Similarly, a few recent studies have focused on the implications of climate change for hydropower production (e.g., Madani and Lund, 2010;Pérez-Díaz and Wilhelmi, 2010;Mehta et al, 2011;Vicuña et al, 2011).…”

Understanding the trade‐offs between water for the environment and water for hydropower in regulated rivers can inform decision making about hydropower system planning, policy and operations, especially with anticipated climate warming–induced changes in runoff. This study used a multireservoir optimisation model to assess the hydropower effects of increasing minimum instream flows (MIFs) and imposing weekly scale down ramp rates (DRRs) in three locations in California's Upper Yuba River (UYR). The UYR is currently used for hydropower generation yet has high potential for freshwater habitat restoration. Trade‐offs between DRRs, MIFs and hydropower generation and revenue are explored with uniform air temperature increases of 0 °C, 2 °C, 4 °C and 6 °C to approximate anticipated regional climate warming. With 6 °C warming, the most ecologically beneficial MIF and DRR reduced hydropower generation by 7.9% and revenue by 5.5% compared with base case management and a historical climate. This has important implications for licensure of the UYR project and other hydropower projects, where multiple benefits under current and potential future conditions must be balanced. This study provides a methodological approach that can be used by water managers, regulators and stakeholders to better understand inherent trade‐offs in allocating water for multiple beneficial uses in a nonstationary hydroclimate.

“…They found that shifting from revenuedriven operations to run-of-river operations results in more natural flow regimes but large (up to 15%) revenue reductions. (Beilfuss 2010) assessed trade-offs between flows and electricity generation among three large hydropower facilities in Mozambique during a 97-year period. They found that re-creating natural flows requires large reductions in electricity generation and firm capacity except during high flow months.…”

Deployment of small-scale hydropower, which generally ranges in capacity from 1-10 MW, may partly depend on its ability to mitigate environmental concerns while generating sufficient revenues. In this paper, we quantify net revenue and downstream flow impact trade-offs of a cascading series of 36 small-scale hydropower facilities under consideration for development in Northeast California. To do so, we develop a net-revenue-maximizing optimization model that determines hydropower operations while capturing key technical and river network constraints. We find that significantly constraining maximum discharges from each facility largely eliminates downstream flow impacts but negligibly changes the 36 facilities' combined operations and net revenues. Thus, we find a negligible trade-off between net revenues and downstream impacts in our study system, suggesting small-scale hydropower can contribute to decarbonization efforts while limiting local environmental impacts on downstream flows at little economic cost.

“…En [3] se plantea un modelo de control de inundaciones para las temporadas de lluvias, aplicando un análisis de confiabilidad y riesgo, basado en los pronósticos hidrológicos también para el proyecto de Tres Gargantas. En Mozambique, se planteó el control de inundaciones utilizando un embalse hidroeléctrico para mitigar el impacto social y reflejando la afectación sobre la generación de energía eléctrica [4]. En Francia, se consideran los elementos de diseño de los diques de protección contra inundaciones [5].…”

López, "Modelo para el control de inundaciones utilizando dos embalses en paralelo," Rev. ResumenEste artículo presenta un modelo matemático que permite simular el comportamiento de embalses en paralelo, como infraestructura primaria para el control de inundaciones, utilizando el concepto de embalse multipropósito. El modelo se conforma de un conjunto de ecuaciones que representan los flujos de entrada y salida de los embalses y las restricciones asociadas al control de inundaciones. La validación del modelo se realiza utilizando los parámetros técnicos de dos embalses del Sistema Eléctrico Colombiano. Con este desarrollo se ofrece al mercado eléctrico nuevas herramientas orientadas a la toma de decisiones relacionadas con la prevención y el control de inundaciones.Palabras clave: control de inundaciones; embalse multipropósito; fenómeno de La Niña. AbstractThis article presents a mathematical model to simulate the behavior of two reservoirs in parallel as primary infrastructure for flood control using the concept of Multipurpose Reservoir. The model is made up of a set of equations that represent the inflows and outflows of reservoirs and constraints associated with flood control. Model validation is performed using the technical parameters of two reservoirs of the Colombian Electric System. With this development, new decision-oriented tools are offered to the electricity market related to flood prevention and control.
