“…In Florida, several hydrologic models have been developed specifically for the coastal wetland transition zone between the Everglades, an expansive freshwater wetland on the mainland, and Florida Bay. The Southern Inland Coastal System model (Swain et al, 2004) and the Tides and Inflows in the Mangrove Ecotone (TIME) model (Langevin et al, 2005) quantify freshwater flow and solute transport between the southern Everglades and northeastern Florida Bay. The Biscayne and Southern Everglades Coastal Transport model (Swain et al, 2019) builds on TIME and the Biscayne model (Lohmann et al, 2012) to account for additional hydrologic attributes of the southern Florida peninsula and surrounding tidal water bodies.…”

For ecosystem models to be applicable outside their context of development, temporal and spatial transferability must be demonstrated. This presents a challenge for modeling intertidal ecosystems where spatiotemporal variation arises at multiple scales. Models specializing in tidal dynamics are generally inhibited from having wider ecological applications by coarse spatiotemporal resolution or high user competency. The Tidal Inundation Model of Shallowwater Availability (TiMSA) uniquely simulates tides to empirically derive a time-integrated measure of availability for a shallow-water depth range defined by the user. To evaluate temporal and spatiotemporal transferability, we employed TiMSA at the development site in the Florida Keys and at novel subsites in the Florida Bay (application site) under a different time period (application period). We used foraging little blue herons (Egretta caerulea) as the ecological unit with which to constrain the model's "water depth window," that is, range of water depths to estimate shallow-water availability.At the development site, temporally consistent water depth windows contrasted with interannual variation in shallow-water availability, which revealed short-term changes in Little Blue Heron foraging habitat. At the application site, water depth accuracy varied by subsite and was correlated with spatial error in bathymetric elevation. Although TiMSA parameters were sensitive to environmental temporal variation and uncertainty in spatial data, a spatially explicit water depth window generated reliable estimates of shallow-water conditions over space and time at the development and application sites. By exploring the contributing factors to model error, we provide solutions to reduce uncertainty of TiMSA parameters at potential application sites and recommendations for addressing bathymetric inaccuracy in digital elevation models. Accurately quantifying spatiotemporal changes of shallow water has implications for monitoring habitat conditions for tidally influenced species and projecting future changes to coastal ecosystems in response to anthropogenic stressors and natural disturbances such as sea level rise.

Assessing the Effectiveness of Spreader Canals in Delivering Water to Marshes

et al. 2011

Hydrodynamic modeling is usually necessary for predicting water deliveries to marshes from source reservoirs. A novel approach is developed that decouples the delivery structure hydraulics from the marsh hydrodynamics, allowing these components to be analyzed both separately and in combination. This approach is applied to assess the effectiveness of incorporating spreader canals into water delivery systems in Everglades National Park. The results show that Manning's n in the marsh can be reasonably approximated as a function of VR, in which V is the flow velocity and R is the hydraulic radius; spreader canals can provide substantial percentage increases in water deliveries compared to the smaller structure tailwater pools, and spreader canal outflows can be linear functions of the length of the spreader canal.
