Variation and uncertainty in estimated evaporation was determined over time and between two locations in Florida Bay, a subtropical estuary. Meteorological data were collected from September 2001 to August 2002 at Rabbit Key and Butternut Key within the Bay. Evaporation was estimated using both vapor flux and energy budget methods. The results were placed into a long-term context using 33 years...

BIOME-BGC is a general ecosystem model designed to simulate hydrologic and biogeochemical processes across multiple scales. The objectives of this investigation were to compare BIOME-BGC estimates of hydrologic processes with observed data for different boreal forest stands and investigate factors that control simulated water fluxes. Model results explained 62 and 98% of the respective variance...

Evaporation was determined by the energy-budget method for Mirror Lake during the open water periods of 1982–1987. For all years, evaporation rates were low in spring and fall and highest during the summer. However, the times of highest evaporation rates varied during the 6 yr. Evaporation reached maximum rates in July for three of the years, in June for two of the years, and in August for one ...

The Priestley–Taylor equation (PTE) is frequently applied in actual areal evapotranspiration (ET) estimation methods for obtaining the maximum daily rate of evaporation with data from sub-humid conditions. Since PTE was parameterized under humid conditions, a temperature correction is necessary to avoid overestimation of the maximum rate of ET. Wet-environment surface temperature (Tws), a proxy...

approved: John P. Bolte The WET-Temp (Watershed Evaluation Tool Temperature) model is designed to take advantage of spatially explicit datasets to predict stream temperature distribution. Datasets describing vegetation cover, stream network locations, elevation and stream discharge are utilized by WET-Temp to quantify geometric relationships between the sun, stream channel and riparian areas. T...

Evaporation coefficient (KE) is defined as the ratio of actual evaporation over potential evaporation under the same atmospheric conditions. The use of KE provides an alternative means for evaluating soil moisture status and quantifying soil evaporation by reducing in situ measurements. However, little effort has been made to evaluate the estimation of KE over soil surfaces. In this study, a re...

Evaporation estimates are often used in water balance calculations to determine seepage rates from feedyard holding ponds and lagoons. These estimates have been made using empirical equations derived for clear water, Class A Pan evaporation measurements using clear water, and rule-of-thumb estimates. However, feedyard effluent has different physical and chemical characteristics than clear water...

Abstract The present study sought to use a 20 mm thick foam coated with cement slurry and blue ball diameter of 6 cm, as physical methods, in 50 80% surface covers, their composite coverage the Colorado pan. water depth pans was measured for 1 month autumn season. Then, pans' daily evaporation calculated compared amount control evaporation. results indicated that combined method (plastic foam) ...

© Appl. Rheol. 15 (2005) 390–397 Abstract: We report on the design and implementation of an evaporation blocker for cone-plate and plate-plate geometries. In addition to minimizing sample evaporation by trapping the saturated vapor inside a sample chamber, an important feature of the evaporation blocker is the suppression of solvent transport through condensation. Validation tests with DI-water...
