“…: animal unit; TWh = terawatt hour. Riverine ecosystems are particularly sensitive to environmental change occurring within the basin because of the high degree of longitudinal connectivity; for instance, a large dam can alter thermal, sediment, and flow regimes far downstream (Richter et al 1998;Graf 2006). Headwater disturbances (eg surface mining) can modify water quality and ecological conditions for many kilometers (Lindberg et al 2011).…”

Riverine macrosystems are described here as watershed‐scale networks of connected and interacting riverine and upland habitat patches. Such systems are driven by variable responses of nutrients and organisms to a suite of global and regional factors (eg climate, human social systems) interacting with finer‐scale variations in geology, topography, and human modifications. We hypothesize that spatial heterogeneity, connectivity, and asynchrony among these patches regulate ecological dynamics of whole networks, altering system sensitivity, resistance, and resilience. Long‐distance connections between patches may be particularly important in riverine macrosystems, shaping fundamental system properties. Furthermore, the type, extent, intensity, and spatial configuration of human activities (eg land‐use change, dam construction) influence watershed‐wide ecological properties through effects on habitat heterogeneity and connectivity at multiple scales. Thus, riverine macrosystems are coupled social–ecological systems with feedbacks that influence system responses to environmental change and the sustainable delivery of ecosystem services.

“…Richter, Baumgartner, Powell, and Braun (1996) and Richter, Braun, Mendelson, and Master (1997) developed hydrologic indicators (HIs) to assess the degree to which human disturbance affects hydrologic regimes and proposed the range of variability approach (RVA) with the aim of setting stream flow-based river management targets that incorporate the concepts of hydrologic variability and aquatic ecosystem integrity. RVA has been proven a practical and effective means of assessing hydrological alteration and has been applied to many river basins around the world that represent a variety of watershed and hydrologic regime types (Knight et al, 2014, Koel & Sparks, 2002, Richter, Baumgartner, Braun, & Powell, 1998, Shiau & Wu, 2004b. The Three Gorges Reservoir had more significant impacts on monthly sediment concentration than monthly discharge (Zhang, Wu et al, 2012a).…”

The natural abundance of larval fish of four carp species has been affected adversely by the Three Gorges Reservoir in the Yangtze River. One of the methods to conserve fish is to regulate hydrology regimes to keep them optimal for species spawning. Thirty‐two hydrologic indicators (HIs) associated with the hydrologic regime of the spawning sites at the Jianli reach were analyzed with the range of variability approach. Outputs were correlated with abundance of larval fish by a genetic programming approach to explore the relationship between the hydrologic regime and fish abundance. Results showed that rate of rise for discharge and average monthly discharge in June, October, and December; rate of rise for water level, average monthly water level in May, June, July, October, and November, and 1‐, 3‐, 7‐, and 30‐day maximum water level; and high pulse duration for sediment concentration and average monthly sediment concentration in June, July, and October were key factors that affected fish species abundance. All of these HIs changed greatly after impoundment of the Three Gorges Reservoir since 2003. Discharge and water level played the dominant role in reproduction of four carp species when the change of sediment concentration kept stable. However, when the sediment concentration declined over the limited range, it replaced discharge and water level as having the dominant role in reproduction. Two relationships between abundance of larval fish and HIs were identified from genetic programming results to explore an indicator impact matrix for use in eco‐hydrologic management through change of some HIs to improve fish abundance.

“…The IHA method was implemented to assess hydrological alteration of streamflow regime parameters between two defined periods: historical and far or near future at a given river reach (Richter et al, 1996(Richter et al, , 1998. The IHA method contains a subset of 33 parameters grouped into five sets of hydrologic features: magnitude, timing, frequency, duration and rate of change (The Nature Conservancy 2009).…”

“…SWAT is a hydrological model that simulates run-off and streamflow (among other variables) with a daily time step on a catchment scale, which is suitable for large-scale studies (Arnold, Srinivasan, Muttiah & Williams, 1998). The SWAT model has been used in combination with the Indicators of Hydrologic Alteration (IHA) methodology (Richter, Baumgartner, Braun & Powell, 1998;Richter, Baumgartner, Powell & Braun, 1996) to assess climate change impact on a single fish species habitat suitability by Morid, Delavar, Eagderi and Kumar (2016) and Papadaki et al (2015). The IHA consists of 33 parameters that describe the hydrological regime as: magnitude, timing, frequency, duration and rate of change (The Nature Conservancy 2009).…”

Climate change is expected to affect the flow regime, cause loss of habitat, change community composition and behavioural habits of fish. This study assessed the impact of climate change on ecologically relevant streamflow conditions for fish migration and spawning in the Vistula and the Odra river basins. Streamflow simulations obtained with the Soil and Water Assessment Tool (SWAT) for the historical period and two future horizons were driven by nine bias‐corrected EURO‐CORDEX Regional Climate Models under two greenhouse gas concentration trajectories. This study identified a subset of Indicators of Hydrological Alteration (IHA) that are relevant for pike, Esox lucius L., chub, Squalius cephalus (L.), and Atlantic salmon, Salmo salar L. IHA indicators were calculated and compared for different scenarios. An index‐based framework identified that all considered species will be impacted by climate change, with Atlantic salmon facing the largest impact. The model's uncertainty was addressed through an aggregation method that assessed inconsistencies in the model's response.
