A Hybrid Framework for Rapidly Locating Transition Zones: A Comparison of Event‐ and Response‐Based Return Water Levels in the Suwannee River FL

Abstract

Transition zones are stretches of river where extreme water levels can arise through the interaction of multiple drivers such as elevated river discharge, storm surge, and high tide (Bilskie & Hagen, 2018). Transition zones are likely to exist along rivers throughout the world and tend to be most dramatically revealed during catastrophic flood events, such as Hurricane Harvey (2017) where coincident heavy rainfall and surge flooded Houston and the surrounding area (Stephens et al., 2022;Valle-Levinson et al., 2020). In January 2012, elevated inland water levels triggered precautionary evacuations in the northern Netherlands, as storm surges blocked gravity-driven

Quantifying compound flood event uncertainties in a wave and tidally dominated coastal region: The impacts of copula selection, sampling, record length, and precipitation gauge selection

“…Previous studies have shown model inputs (e.g., gauge measurements, digital elevation models, distributions) pose a significant source of uncertainty on results (Bates et al, 2014;Coveney & Fotheringham, 2011;Saint-Geours et al, 2015;Sampson et al, 2014). There is an increase in studies evaluating current methodologies and their influence on design event estimates (Arns et al, 2013;Jane et al, 2020Jane et al, , 2022Lucey & Gallien, 2022;Sadegh et al, 2018). Arns et al (2013) explores how design events are influenced by detrending methods, utilized sampling, and distribution selection.…”

A Statistics‐Based Analytical Framework for Intratidal and Tidally Averaged Salinity Distribution in Estuaries

“…In terms of mean annual river discharge (300 m 3 /s) and drainage area (25,770 km 2 ), it is the second largest river in Florida (Farrell et al., 2005). As the Suwannee river flows to the Gulf of Mexico, it is fed by three major tributaries, the Apalaha, Withlacoochee, and Santa Fe rivers (Jane et al., 2022). At its lower reaches, the river bifurcates into two branches, East and West Pass.…”

Moving from total risk to community-based risk trajectories increases transparency and equity in flood risk mitigation planning along urban rivers

“…The 100 year flood, based on exceedance probabilities of past, stationary forcing conditions, is the current standard for floodplain management within state and federal agencies in the United States. However, identifying a single event that constitutes a 100 year flood is not straightforward [29][30][31], particularly in the Californian context where some of the most destructive floods, including the 1861-62 flood [32] and the flooding that occurred in early 2023, were not created by a single rainfall event but by a sequence of atmospheric rivers occurring in close succession.…”
