Changing River Flood Timing in the Northeastern and Upper Midwest United States: Weakening of Seasonality over Time?

Abstract (from Water): Climate change is likely to impact precipitation as well as snow accumulation and melt in the Northeastern and Upper Midwest United States, ultimately affecting the quantity and seasonal distribution of streamflow. The objective of this study is to analyze seasonality of long-term daily annual maximum streamflow (AMF) records and its changes for 158 sites in Northeastern and Upper Midwest Unites States. A comprehensive circular statistical approach comprising a kernel density method was used to assess the seasonality of AMF. Temporal changes were analyzed by separating the AMF records into two 30-year sub-periods (1951–1980 and 1981–2010). Results for temporal change in seasonality showed...

Final Report: Slowing the Flow for Climate Resilience: Reducing Vulnerability to Extreme Flood and Drought Events

“Slowing the flow” is an ecological flood mitigation technique that uses riparian ecosystems to delay the rate at which water passes through a watershed by increasing upstream storage in soil, vegetation, surface water, and ground water. This project assessed the potential contributions of slow-the-flow watershed management in a changing climate through a combination of original research, stakeholder workshops, and the establishment of a stakeholder working group. Research, co-produced with stakeholders, investigates the effects of climate and riparian conservation on river flows, sediment transport, and nutrient loadings. Two studies developed and applied models and data to measure the impacts of natural infrastructure...
