“…Conversely, subbasins with a high WQRI represent high priorities for interventions, such as restoration, BMPs, or urban green and gray infrastructure strategies to improve water quality, depending on local land use and management conditions (e.g., Figure 6b). Many of these strategies could also yield benefits for flood‐risk reduction and water provisioning during droughts (Chausson et al., 2020; DeLong et al., 2021; Griscom et al., 2017; Kousky et al., 2013). We found that the highest risk regions (WQRI >1) comprised 16.4% of the entire watershed.…”

“…Nature‐based solutions, such as conservation of wetlands and forests, restoration of degraded natural habitats, agricultural field measures or “best management practices” (BMPs), and managed retreat can all play a role in improving the resilience of watersheds (Antolini et al., 2020; Johnson et al., 2020; Keesstra et al., 2018; Suttles et al., 2021). These solutions may be less costly and faster to implement than hardened infrastructure solutions, and can also provide additional co‐benefits like improved access to greenspace and recreation, economic opportunities, as well as benefits for fish and wildlife habitat and biodiversity (Bassi et al., 2021; Chausson et al., 2020; DeLong et al., 2021; Keesstra et al., 2018). Among nature‐based solutions, floodplain restoration is expected to have the greatest benefits for both water quality and flood‐risk reduction (Suttles et al., 2021).…”

Extreme weather is associated with a variety of water quality issues that can pose harm to humans and aquatic ecosystems. Under dry conditions, contaminants become concentrated in streams with a greater potential for harmful algal blooms, while wet conditions can cause flooding and broadcast pollution. Developing interventions to improve water quality in a changing climate requires a better understanding of how hydroclimatic variability affects watershed processes, and which places are most vulnerable. We developed a Soil and Water Assessment Tool model of the Cape Fear River Basin (CFRB) in North Carolina, USA, representing contemporary land use, point and non‐point sources, and weather conditions from 1979 to 2019. The CFRB is a large, complex river basin undergoing urbanization and agricultural intensification, with a history of droughts and floods. To identify intervention priorities, we developed a Water Quality Risk Index (WQRI) using the average and variability of contaminant loads across dry, normal and wet conditions. The landscape generally contributed the majority of pollutants (e.g., via erosion, fertilizer and manure applications), including 90.1% of sediment, 83.2% of total nitrogen, and 52.4% of total phosphorus at the City of Wilmington's drinking water intake, yet point sources were influential during dry periods. Approximately 16% of the watershed contributed most of the pollutants across conditions—these represent priority locations for interventions such as restoration, urban, or agricultural best management practices. The WQRI approach considering risks to water quality across conditions can help identify locations where interventions are more likely to improve water quality under climate change.

Extreme weather conditions are associated with a variety of water quality issues that can pose harm to humans and aquatic ecosystems. Under dry extremes, contaminants become more concentrated in streams with a greater potential for harmful algal blooms, while wet extremes can cause flooding and broadcast pollution. Developing appropriate interventions to improve water quality in a changing climate requires a better understanding of how extremes affect watershed processes, and which places are most vulnerable. We developed a Soil and Water Assessment Tool model of the Cape Fear River Basin (CFRB) in North Carolina, USA, representing contemporary land use, point and non-point sources, and weather conditions from 1979 to 2019. The CFRB is a large and complex river basin undergoing urbanization and agricultural intensification, with a history of extreme droughts and floods, making it an excellent case study. To identify intervention priorities, we developed a Water Quality Risk Index (WQRI) using the load average and load variability across normal conditions, dry extremes, and wet extremes. We found that the landscape generated the majority of contaminants, including 90.1% of sediment, 85.4% of total nitrogen, and 52.6% of total phosphorus at the City of Wilmington's drinking water intake. Approximately 16% of the watershed contributed most of the pollutants across conditions-these represent high priority locations for interventions. The WQRI approach considering risks to water quality across different weather conditions can help identify locations where interventions are more likely to improve water quality under climate change.
