“…The Integrated Plan also provides an important foundation for developing and testing a basin-specific decision support system that can examine tradeoffs between different waterallocation schemes for people, fish and wildlife (see Bovee et al, 2008). Stream flows could be enhanced (e.g., increased, cooled) during critical periods by proper planning and forecasting and reservoir/irrigation manipulation.…”

“…The habitat analysis focused on suitable hydraulic features (e.g., depth and velocity at a given discharge) and not water temperature since two-dimensional simulations of water temperature were not available. The watershed model (Mastin 2008) provided a discharge time series in each reach for baseline , P1, and P2 scenarios; a river-management model (Zagona et al 2001) modified the discharge time series with Yakima River operational rules (USBR 2002); a 2D model (Steffler and Blackburn 2002) provided spatially explicit depth and velocity; while an expert panel provided salmonid habitat criteria using a Delphi consensus approach (Bovee et al 2008;Zuboy 1981). Discharge-habitat functions were generated for each salmonid life stage (e.g., spawning, rearing) in main stem and side channels, and habitat time series for baseline, P1 and P2 scenarios.…”

We provide an overview of an interdisciplinary special issue that examines the influence of climate change on people and fish in the Yakima River Basin, USA. Jenni et al. (2013) examines how changes in stream flow will affect salmonids with a rule-based fish habitat model. Our simulations indicate that future summer will be a very challenging season for salmonids when low flows and high water temperatures can restrict movement, inhibit or alter growth, and decrease habitat. While some of our simulations indicate salmonids may benefit from warmer water temperatures and increased winter flows, the majority of simulations produced less habitat. The floodplain and tributary habitats we sampled are representative of the larger landscape, so it is likely that climate change will reduce salmonid habitat potential throughout particular areas of the basin. Management strategies are needed to minimize potential salmonid habitat bottlenecks that may result from climate change, such as keeping streams cool through riparian protection, stream restoration, and the reduction of water diversions. An investment in decision analysis and support technologies can help managers understand tradeoffs under different climate scenarios and possibly improve water and fish conservation over the next century.

“…1). Despite extensive urban encroachment and revetment, there are numerous secondary channels in this reach that remain interconnected at moderate discharges (Bovee et al 2008). The Wapato reach has a total valley length of approximately 35 km, extending from Union Gap to the confluence of Satus Creek, near Sunnyside, Washington ( Fig.…”

“…The Wapato reach, headed by the Fig. 1 The location of five reaches that were identified as important to salmonids in the Yakima River in southcentral Washington (Snyder and Stanford 2001;Bovee et al 2008). The two lower reaches (Gap and Wapato) are the focal areas highlighted in our study Sunnyside Diversion Dam, has a 5 % exceedance flow of 204.2 cms, a 50 % exceedance flow of 35.4 cms, and a 90 % exceedance flow of 9.6 cms.…”

“…For every discharge in the flow series, there is a corresponding habitat value from the discharge-habitat function. The watershed model (Mastin 2008) provided the three unregulated hydrographs (baseline, P1, P2), RiverWare™ modified them with Yakima River operational rules (e.g., storage, diversions, minimum flows), while an expert panel provided fish habitat criteria for each species and life stage (Bovee et al 2008). Once the datasets were assembled, we evaluated the effects of climate change on salmonid habitats in the Yakima River in four steps.…”

We evaluated the potential effects of two climate change scenarios on salmonid habitats in the Yakima River by linking the outputs from a watershed model, a river operations model, a two-dimensional (2D) hydrodynamic model, and a geographic information system (GIS). The watershed model produced a discharge time series (hydrograph) in two study reaches under three climate scenarios: a baseline , a 1-°C increase in mean air temperature (plus one scenario), and a 2-°C increase (plus two scenario). A river operations model modified the discharge time series with Yakima River operational rules, a 2D model provided spatially explicit depth and velocity grids for two floodplain reaches, while an expert panel provided habitat criteria for four life stages of coho and fall Chinook salmon. We generated discharge-habitat functions for each salmonid life stage (e.g., spawning, rearing) in main stem and side channels, and habitat time series for baseline, plus one (P1) and plus two (P2) scenarios. The spatial and temporal patterns in salmonid habitats differed by reach, life stage, and climate scenario. Seventy-five percent of the 28 dischargehabitat responses exhibited a decrease in habitat quantity, with the P2 scenario producing the largest changes, followed by P1. Fry and spring/summer rearing habitats were the most sensitive to warming and flow modification for both species. Side channels generally produced more habitat than main stem and were more responsive to flow changes, demonstrating the importance of lateral connectivity in the floodplain. A discharge-habitat sensitivity analysis revealed that proactive management of regulated surface waters (i.e., increasing or decreasing flows) might lessen the impacts of climate change on salmonid habitats.

Development of eco‐hydraulic model for assessing fish habitat and population status in freshwater ecosystems

An eco‐hydraulic model is described, namely, “WW‐Eco‐tools.” The model is composed of hydro‐morpho‐dynamic, habitat, and population models. Fish habitat suitability models assess habitat quality, based on abiotic parameters, namely, flow velocity, depth, and substratum data. These are all derived from a hydro‐morpho‐dynamic model. The relationships between parameters and habitat features are represented as suitability index curves (SI curves) or fuzzy rules. To dynamically simulate fish species, two different population models are developed. The first is converted from a logistic population concept. Its model parameters are related to time‐dependent fish habitat conditions, namely, weighted usable areas and an overall suitability index. The second model is based on a matrix population concept, with numbers as the only state vector. Age‐specific fecundities and survival rates depend on the habitat qualities defined in the matrix population model. The eco‐hydraulic model provides very promising results, highlighting the fundamental role of temporal variability of hydro‐morphological parameters in structuring habitat and populations of fish species. Using this software to anticipate water management changes, simulated population trends can help decision‐makers optimize management measures.
