Impact/Purpose:
The overall objective is to develop modeling and decision support capabilities that allow environmental managers and planners to protect, conserve, and restore aquatic habitats and species.
Description:
The provision of habitat for fish is an important service provided by rivers. Future land development and climate change will likely alter several aspects of habitat, including flow. We have used hierarchical models to predict the presence of 25 fish species within the Albemarle-Pamlico basin, using predictors of land use, flow, temperature, and environmental setting from the USGS NHD Plus dataset. The most parsimonious models for these species typically included positive responses to either flow or velocity. These models are being linked within the FRAMES modeling framework where dynamic hydrologic and hydrodynamic models (SWAT and WASP) provide time-series inputs for the habitat models. This framework can serve as a tool for the assessment of flow alteration in the context of multiple stressors.
