Aaron Sidder, Science Writer Citation: Sidder, A. The authors note that management decisions for large-river floodplains will likely depend on specific locations. The study highlights the challenges of managing and restoring rivers under changing climate scenarios and management imperatives. The benefits from inundation are lower in areas with an incised channel and greater in areas where sediment buildup increases river-floodplain linkages. Increasing connectivity turns out to be highly location dependent. In addition, the authors evaluated how future climate change scenarios could affect floodplain connectivity, a key component in climate resiliency. However, the model indicated that floodplain modifications have limited utility to mitigate nutrient inputs-a scenario without levees increased denitrification to only 3.6% of the current nitrogen load. The results indicate that increasing floodplain inundation would significantly bolster waterfowl habitat, particularly in expansive floodplains. They evaluated how submerging floodplains would affect waterfowl habitat and denitrification. The authors used an inundation model focused on the lower reaches of the river, the 500 miles (around 800 kilometers) from Rulo, Neb., to the confluence with the Mississippi River. The researchers modeled a management approach that simulated floodplain inundation over several scenarios to understand how flooding conditions would affect wildlife habitat and nutrient processing. river-the Missouri-which is subject to heavy nutrient runoff from the region’s extensive agriculture. These floods have prompted river managers to consider how to increase floodplains’ resiliency while also reaping the socioeconomic benefits that rivers and floodplains provide. As extreme weather events increase, so too has flooding, often resulting in catastrophic damage.
