“…Fishway engineering also borrows from the field of “mimetics” in which characteristics of natural systems are engineered or synthesized (FAO/DVWK ; Jungwirth, ). Operational research methods are increasingly being combined with geographical information systems of barrier distributions to plan how best to apply fish passage solutions at existing barriers (King, O'Hanley, Newbold, Kemp, & Diebel, ; McKay, Schramski, Conyngham, & Fischenich, ; Neeson et al., ), and to decide how to plan future, more eco‐friendly hydropower development (Ioannidou & O'Hanley, ).…”

Much effort has been devoted to developing, constructing and refining fish passage facilities to enable target species to pass barriers on fluvial systems, and yet, fishway science, engineering and practice remain imperfect. In this review, 17 experts from different fish passage research fields (i.e., biology, ecology, physiology, ecohydraulics, engineering) and from different continents (i.e., North and South America, Europe, Africa, Australia) identified knowledge gaps and provided a roadmap for research priorities and technical developments. Once dominated by an engineering-focused approach, fishway science today involves a wide range of disciplines from fish behaviour to socioeconomics to complex modelling of passage prioritization options in river networks. River barrier impacts on fish migration and dispersal are currently better understood than historically, but basic ecological knowledge underpinning the need for effective fish passage in many regions of the world, including in biodiversity hotspots (e.g., equatorial Africa, South-East Asia), remains largely unknown.

“…Applications are biased, however, to developed, northern temperate regions, where the majority of viable hydropower and water storage potential has already been realized. Installation of new infrastructure is rarely considered, though there are exceptions (Ziv et al 2012;Ioannidou and O'Hanley 2018). Existing methods also frequently apply assumptions appropriate to a limited number of economically important fish taxa, usually with anadromous migrations (e.g., Salmonidae).…”

“…The use of river pathways represents a novel way to describe river connectivity that contrasts markedly from existing river connectivity metrics. Second, current models focus exclusively on removal/mitigation of existing barriers (Neeson et al 2015) or, in a limited number of cases, the location of new dams (Ziv et al 2012;Ioannidou and O'Hanley 2018). In contrast, our model combines both dam placement and removal decisions.…”

Optimizing hydropower dam location and removal in the São Francisco river basin, Brazil to balance hydropower and river biodiversity tradeoffs

To support eco-friendly hydropower planning in developing regions, we propose a spatial optimization model for locating dams to balance tradeoffs between hydropower generation and migratory fish species richness. Our model incorporates two special features. First, it is tailored to the dispersal of tropical migratory fishes, which require long, unimpeded river stretches to complete their life-cycle. To model fish with this type of dispersal pattern, we introduce the concept of a river pathway, which represents a novel way to describe river connectivity. Second, it combines decisions about dam placement and removal, thus facilitating opportunities for hydropower offsetting. We apply our model to the São Francisco River basin, Brazil, an area of hydropower-freshwater biodiversity conflict. We find that dams have reduced weighted migratory fish richness 51% compared to a pre-dam baseline. We also find that even limited dam removal has the potential to significantly enhance fish biodiversity. Offsetting the removal of a single dam by the optimal siting of new dams could increase fish richness by 25% above the current average.Moving forward, optimizing new dam sites to increase hydropower by 20%, rather than selecting the fewest number of dams, could reduce fish species losses by 89%. If decisions about locating new dams are combined with dam removal, then a win-win can even be achieved with 20% greater hydropower and 19% higher species richness. Regardless of hydropower targets and dam removal options, a key observation is that optimal sites for dams are mostly located in the upper reaches of the basin rather than along the main stem of the São Francisco River or its main tributaries.

“…For example, Hosnar and Kovač-Kralj [12] identify the optimal installation locations by maximizing an ecoprofit objective at technological, economic, environmental, and social constraints. To identify the appropriate hydropower dam location, Loannidou and O'Hanley [13] develop a mixedinteger linear programming model to optimize the hydropower potential with the consideration of river connectivity. In these studies, the future power generation and hydrologic dynamics are described by the empirical formulas in the cumulative form.…”

Planning of Cascade Hydropower Stations with the Consideration of Long‐Term Operations under Uncertainties

In the location-related planning of a hydropower system, the consideration of future operations under uncertainties can make the decisions sustainable and robust. Then, it is of great importance to develop an effective approach that deals with the long-term stochasticity due to the long-lasting effects of the location selections. Thus, we propose a multistage stochastic programming model to optimize the planning decisions of cascade hydropower stations and the long-term stochastic operations in an integrated way. The first stage (i.e., the planning stage) in the model deals with the location and capacity decisions of the hydropower stations, while the subsequent stages implement the scheduling decisions under each stagewise stochastic scenario. To address the curse of dimensionality caused by the long-term stochastic operations, we further propose a novel dimensionality reduction approach based on dual equilibrium to transform the multistage model into a tractable two-stage stochastic program. The applicability of our approach is validated by a case study based on a basin of Yangtze River, China, and corresponding sensitivity analysis.
