“…Annual estimates by these models (1,350-1,600 mm) are similar to 1,300-1,400 mm as reported by Abtew et al (2005b) and Huebner (2008). However, such variability in ET estimates from different approaches reflects the difficulties in accurately estimating ET in wetlands (Rushton 1996, Shoemaker et al 2008. There is no instrument that can directly measure evapotranspiration; although lysimeters have been deemed suitable for wetlands with herbaceous vegetation (Koerselman and Beltmann 1988), they are impractical where there is large woody vegetation.…”

Water budget parameters are estimated for Shark River Slough (SRS), the main drainage within Everglades National Park (ENP) from 2002 to 2008. Inputs to the water budget include surface water inflows and precipitation while outputs consist of evapotranspiration, discharge to the Gulf of Mexico and seepage losses due to municipal wellfield extraction. The daily change in volume of SRS is equated to the difference between input and outputs yielding a residual term consisting of component errors and net groundwater exchange. Results predict significant net groundwater discharge to the SRS peaking in June and positively correlated with surface water salinity at the mangrove ecotone, lagging by 1 month. Precipitation, the largest input to the SRS, is offset by ET (the largest output); thereby highlighting the importance of increasing fresh water inflows into ENP for maintaining conditions in terrestrial, estuarine, and marine ecosystems of South Florida.

“…The importance of accurately calculating evapotranspiration volume, a large portion of the water budget, has been demonstrated (Shoemaker et al 2008), and precalculated evapotranspiration rates have been shown to adequately represent evaporative mass transfer (Wang et al 2007). However, these evapotranspiration rates lack the temporal and spatial variability to calculate latent heat fluxes.…”

Numerical modeling is needed to predict environmental temperatures, which affect a number of biota in southern Florida, U.S.A., such as the West Indian manatee (Trichechus manatus), which uses thermal basins for refuge from lethal winter cold fronts. To numerically simulate heat-transport through a dynamic coastal wetland region, an algorithm was developed for the FTLOADDS coupled hydrodynamic surface-water/ground-water model that uses formulations and coefficients suited to the coastal wetland thermal environment. In this study, two field sites provided atmospheric data to develop coefficients for the heat flux terms representing this particular study area. Several methods were examined to represent the heat-flux components used to compute temperature. A Dalton equation was compared with a Penman formulation for latent heat computations, producing similar daily-average temperatures. Simulation of heat-transport in the southern Everglades indicates that the model represents the daily fluctuation in coastal temperatures better than at inland locations; possibly due to the lack of information on the spatial variations in heat-transport parameters such as soil heat capacity and surface albedo. These simulation results indicate that the new formulation is suitable for defining the existing thermohydrologic system and evaluating the ecological effect of proposed restoration efforts in the southern Everglades of Florida.
