     "text": "has undertaken a multi-year study to research methods for detecting and addressing potential trends in flood frequency distributions because of changes in climate, land use, and other potential drivers of change. This multi-state region represents complex variability in topography, ecoregions, land use, land cover, and climate. The region is characterized by abrupt transitions among high-relief, semi-mountainous areas, well-drained moderate-elevation plains, poorly drained low-elevation glaciated prairies, and other complex geologic and hydrologic features. The land use is mainly pasture and small grains to the west. The Corn Belt covers much of the center and eastern portion of the region and has recently expanded to the west and north. The region also contains major urban-suburban areas, centered on Chicago, Minneapolis-St. Paul, and St. Louis, which have expanded substantially during the proposed study period and thus are another source of non-stationarity."

This study is intended to provide a framework for addressing potential non-stationarity issues in statewide flood-frequency updates that commonly are conducted by the USGS in cooperation with state DOTs throughout the nation on an ongoing basis. This will be achieved through the following primary objectives:"

     "text": "Peak-flow frequency analysis is essential for flood insurance studies, floodplain management, and the design of transportation infrastructure. In recent decades, better understanding of long-term hydroclimatic persistence, as well as concerns about potential climate change and land-use change have caused the stationarity assumption, underpinning for flood-frequency analysis, to be reexamined. Although many important water-management activities are independently conducted within the sociopolitical state boundaries, regional hydrologic complexities transcend the state boundaries and are more efficiently handled from a regional perspective. This investigation will be conducted in collaboration with a national study funded by the Federal Highway Administration and will focus on specific issues that have the most impact on flood-frequency analysis within the multi-state region."
