“…For example, costbenefit analyses are increasingly being performed, often in terms of improvements in water quality (Eisen-Hecht and Kramer, 2002;Mourato et al, 2005), but also relating to ecohydromorphology. Kuby et al (2005) developed a modelling method for dam removals in the Willamette River basin in Oregon, which compared the potential benefits for salmonid migration against socio-economic losses (water storage and hydropower) under different scenarios, and which suggested significant habitat connectivity benefits for relatively low levels of dam removal. Willis and Garrod (1999) considered the balance between water abstraction and the potential losses of recreational income associated with low flows, and showed that recreational angling in particular could provide financial justification for many types of low flow alleviation.…”

ABSTRACT1. The assessment of links between ecology and physical habitat has become a major issue in river research and management. Key drivers include concerns about the conservation implications of human modifications (e.g. abstraction, climate change) and the explicit need to understand the ecological importance of hydromorphology as prescribed by the EU's Water Framework Directive. Efforts are focusing on the need to develop 'ecohydromorphology' at the interface between ecology, hydrology and fluvial geomorphology. Here, the scope of this emerging field is defined, some research and development issues are suggested, and a path for development is sketched out.2. In the short term, major research priorities are to use existing literature or data better to identify patterns among organisms, ecological functions and river hydromorphological character. Another early priority is to identify model systems or organisms to act as research foci. In the medium term, the investigation of patternprocesses linkages, spatial structuring, scaling relationships and system dynamics will advance mechanistic understanding. The effects of climate change, abstraction and river regulation, eco-hydromorphic resistance/ resilience, and responses to environmental disturbances are likely to be management priorities. Large-scale catchment projects, in both rural and urban locations, should be promoted to concentrate collaborative efforts, to attract financial support and to raise the profile of eco-hydromorphology.3. Eco-hydromorphological expertise is currently fragmented across the main contributory disciplines (ecology, hydrology, geomorphology, flood risk management, civil engineering), potentially restricting research and development. This is paradoxical given the shared vision across these fields for effective river management based on good science with social impact. A range of approaches is advocated to build sufficient, integrated capacity that will deliver science of real management value over the coming decades.

“…The removal of two dams on the Penobscot River in Maine is expected to restore a cultural legacy to the Penobscot Indian Nation, help recover an endangered salmon species, and provide as many as 200 jobs without a loss in total energy production (5). Elsewhere in the United States, trade-off analyses similar to those performed by Ziv et al have shown that one could remove 12 dams in the Willamette River watershed (Oregon) and reconnect over half of the river basin while sacrificing <2% of hydropower and water storage capacity (6).…”

“…On the other hand, their impacts go well beyond disrupting river connectivity; they can signi cantly reduce sediment ow, dampen seasonal ow variation (aka the natural hydrograph ), cause loss of riparian and terrestrial habitat (due to submersion), and promote the spread of aquatic invasive species (Stanford et al, 1996). At the same time, large reservoir dams can deliver additional socio-economic bene ts that run-of-river dams at best only partially provide, such as water storage/supply, ood protection, shing, and recreational opportunities (Kuby et al, 2005;Zheng et al, 2009). Both the socio-economic bene ts and environmental costs of dams can be estimated fairly easily using established market and non-market valuation techniques (MacDonald et al, 2011), suggesting that one might consider integrating adopting a bio-economic analysis framework to optimize large hydropower dam location decisions.…”

“…One study dealing speci cally with hydropower is Kuby et al (2005), who propose the use of a multiobjective optimization model for prioritizing the removal of large hydropower dams. Their model quanti es trade-o s between ecological gains for migratory sh, economic losses from reduced hydropower generation and water storage capacity.…”

We address the problem of locating small hydropower dams in an environmentally friendly manner. We propose the use of a multi-objective optimization model to maximize total hydropower production, while limiting negative impacts on river connectivity. Critically, we consider the so called backwater e ects that dams have on power generation at nearby upstream sites via changes in water surface pro les. We further account for the likelihood that migratory sh and other aquatic species can successfully pass hydropower dams and other arti cial/natural barriers and how this is in uenced by backwater e ects.Although naturally represented in nonlinear form, we manage through a series of linearization steps to formulate a mixed integer linear programing model. We illustrate the utility of our proposed framework using a case study from England and Wales. Interestingly, we show that for England and Wales, a region heavily impacted by a large number of existing river barriers, that installation of small hydropower dams tted with even moderately e ective sh passes can, in fact, create a win-win situation that results in increased hydropower and improved river connectivity.
