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

“…Saltgrass was present in the marshes adjoining the river, but occurred primarily as an understory species. The delta marshes have been shown to have a stronger contribution of freshwater and brackish species and a higher tendency to flooding by freshwater (Bales et al, 2005;Coultas and Lasley, 2001;Raabe et al, in prep.). The presence of saltgrass in different environments indicates that it may alternate as dominant, co-dominant, and understory species depending on conditions.…”

Florida salt marsh vole habitat: lower Suwannee National Wildlife Refuge

The rare Florida salt marsh vole (Microtus pennsylvanicus dukecampbelli) was discovered in spring 2004 by U.S. Fish and Wildlife Service (USFWS) personnel on the Lower Suwannee National Wildlife Refuge. The discovery of three individuals in the southern portion of the refuge renewed hope for effective recovery and protection of this rare animal. Further protection of the Florida salt marsh vole will rely on distribution surveys of the animal and conservation of potential habitat. This report details an effort by the U.S. Geological Survey to map potential habitat sites within the refuge. The Florida salt marsh vole is known to utilize a specific type of salt marsh called saltgrass (Distichlis spicata) as habitat. Hyperspectral imagery acquired in 2002 for mapping general intertidal habitats of the lower Suwannee River and estuary was re-evaluated for this specific habitat. The results of the mapping effort and field reconnaissance identified potential habitat in the salt marshes north and south of the Suwannee River. Saltgrass habitat was fieldidentified at flooded and elevated sites, near the shoreline and toward the marsh interior, and was found occurring with several other marsh species, including three-square sedge, smooth cordgrass, black needlerush, and glasswort. Image-derived saltgrass mapping was only 62% accurate. Positive identification of saltgrass from the imagery was hindered by the variety of environmental conditions and the co-occurrence of saltgrass with other species. Image-derived sites were mapped separately from field-verified locations. The tidal marsh around the Suwannee River delta itself did not support extensive saltgrass-dominant habitat. This was due largely to freshwater flow and dominance of freshwater marsh species in those areas. Where saltgrass was identified as a sparse understory, it could become the dominant cover under different conditions such as drought or decreased river discharge.

“…At its lower reaches, the river separates into two major branches, East Pass and West Pass (Figure 1c). West Pass has an average width of 275 m (Bales et al, 2006), and its bathymetry varies from 0.5 to 7 m (Figure 2), whereas East Pass has an average width of 90 m and its depth varies from 4 to 8 m. West Pass in turn trifurcates into Northern, Wadley, and Alligator Passes, which form its delta. Alligator, Northern, and Wadley passes are around 250–400, 150, and 155 m wide, respectively.…”

“…Tidal ranges are 0.6 and 1.5 m in neap and spring tides, respectively. Tidal influence can reach up to more than 53 km from the mouth (Bales et al, 2006), where the Wilcox U.S. Geological Survey (USGS) station provides water level information.…”

Tidal and Subtidal Variations in Water Level Produced by Ocean‐River Interactions in a Subtropical Estuary

Near yearlong time series measurements of water level elevation from seven stations along the Suwannee River, Florida, were used to characterize, observationally and analytically, the propagation of tidal and subtidal signals along the estuary resulting from tide‐river interactions. Tidal amplitudes and phases were obtained from least squares fits to observed values and used to compare to an analytical model. Subtidal amplitude and phases were characterized by Hilbert empirical orthogonal functions (HEOFs), obtained through complex principal component analysis, and compared to an analytical solution. The landward attenuation of the tidal signal was replicated analytically. The subtidal signal (periods > tides) was also described analytically with an oceanic wave moving landward and a seaward river pulse. The subtidal analytical solution reproduced the competition between the landward and seaward waves and the zone where each wave dominated over the other. Depending on the phase of these landward and seaward subtidal waves, the resulting subtidal signal amplitude could either (a) attenuate landward to a certain location and then increase or (b) amplify landward up to a certain zone and then decrease.
