“…Em alguns estudos realizados em áreas alagadas (wetlands) considerou-se que as mudanças no armazenamento de calor da água foram maiores que as mudanças no armazenamento de energia na biomassa e no ar dentro do dossel (Bidlake et al, 1996;German, 2000) haja vista que a capacidade térmica da água é quase o dobro da capacidade térmica da vegetação, solo e matéria orgânica. Em estudos mencionados por Bidlake et al (1996) e German (2000 que estudam o armazenamento de energia em áreas alagadas, a vegetação deve ser mencionada de vez que, diferentemente da vegetação do presente estudo, a vegetação possuía menor porte e se encontrava completamente alagada no período de inundação.…”

R E S U M OA variação da energia armazenada na biomassa e no ar do dossel pode ser estimada por meio de medidas da temperatura da biomassa e do ar e da distribuição da biomassa, constituindo-se um componente significativo do balanço de energia. Apesar de que estimativas acuradas desse componente do balanço de energia são de difícil obtenção e normalmente desprezadas nos cálculos, sobretudo em análises de períodos longos. Colaborando com a compreensão do fechamento do balanço de energia existente na floresta, este trabalho estimou o estoque de energia disponível na biomassa por meio de dados micrometeorológicos em uma floresta de Vochysia divergens Pohl no Pantanal, em 2007. O armazenamento de energia na biomassa e no ar do dossel foi superior na estação chuvosa em relação à seca; entretanto, a diferença entre o valor máximo e mínimo horário foi maior durante a estação seca. Os valores de armazenamento de energia na biomassa e no ar do dossel em floresta de V. divergens no Pantanal foram, em 2007, similares à energia armazenada em outras florestas tropicais. Energy storage in the biomass and air of the canopy of Vochysia divergens Pohl A B S T R A C TThe variation of the storage energy in the biomass and in the air of the canopy can be estimated by measuring biomass and air temperature and biomass distribution being a significant component of energy balance. Nevertheless, accurate estimates of this component of energy balance are difficult to obtain and usually neglected in the calculations, especially in analysis of long periods. To understand the energy balance in the forest, this study estimated the energy stored in biomass using micrometeorological data in a forest monodominant Vochysia divergens Pohl in Pantanal in 2007. The energy stored in the biomass and in the air of the canopy (S) was higher in rainy season than in dry season, however, the difference between maximum and minimum values was higher during the dry season. The values of S in V. divergens forest in Pantanal in 2007 were similar to storage energy in the other tropical forests.

“…Groundbased evapotranspiration networks in Florida are sparse and were nonexistent prior to 1990. Examples of ground-based evapotranspiration studies include Bidlake andothers (1996), German (2000), Shoemaker and others (2011), Sumner (1997, and Swancar and others (2000).…”

AbstractThe extensive and highly managed surface-water system in southeastern Florida constructed during the 20th Century has allowed for the westward expansion of urban and agricultural activities in Miami-Dade County. In urban areas of the county, the surface-water system is used to (1) control urban flooding, (2) supply recharge to production well fields, and (3) control seawater intrusion. Previous studies in Miami-Dade County have determined that on a local scale, leakage from canals adjacent to well fields can supply a large percentage (46 to 78 percent) of the total groundwater pumpage from production well fields. Canals in the urban areas also receive seepage from the Biscayne aquifer that is derived from a combination of local rainfall and groundwater flow from Water Conservation Area 3 and Everglades National Park, which are west of urban areas of Miami-Dade County.To evaluate the effects of groundwater pumpage on canal leakage and regional groundwater flow, the U.S. Geological Survey (USGS) developed and calibrated a coupled surfacewater/groundwater model of the urban areas of Miami-Dade County, Florida. The model was calibrated by using observation data collected from January 1997 through December 2004...

“…Accurate measurement of ET components is, however, difficult and unreliable [3]. In humid regions such as West-Central Florida, ET is estimated to be 70% of precipitation on an average annual basis [4][5][6]. Despite its significance, ET is traditionally inferred from values of potential ET (PET) or reference ET [7].…”

Simultaneous measurements of soil moisture profiles and water table heads, along a flow path, were used to determine evapotranspiration (ET) along with other components of the water budget. The study was conducted at a small-scale (~0.8 Km2) hydrologic monitoring field site in Hillsborough County, Florida, from January 2002 to June 2004. Frequency Domain Reflectometry soil moisture probes, installed in close proximity to water table monitoring wells were used to derive changes in the soil water storage. A one-dimensional transect model was developed; changes in the soil water storage and water table observations served as input to determine all vertical and lateral boundary fluxes along the shallow water table flow plane. Two distinct land cover environments, grassland and an alluvial wetland forest, were investigated in this particular study. The analysis provided temporally variable ET estimates for the two land covers with annual totals averaging 850 mm for grassland, to 1100 mm for the alluvial wetland forest. Quantitative estimates of other components of a water budget, for example, infiltration, interception capture, total rainfall excess, and runoff were also made on a quarterly and annual basis. Novelty of this approach includes ability to resolve ET components and other water budget fluxes that provide useful parameterization and calibration potential for predictive simulation models.
