* In order to determine best empirical equation when a lack of Lysimeter data occurs, through a comparison between method outputs and evaporation basin data, best empirical equation to measure monthly potential evapotranspiration
of each area is determinable.
The dynamics performed by forests with evapotranspiration
to actively transport quantities of water volumes onto the atmosphere, given that it is controlled by opening of stoma from the vegetation, could be only one of its functions according to the proposal presented through the biotic pump theory, developed by research from physicists like Dr.
Rainfall and evapotranspiration
affect soil water dynamics (Huang and Gallichand 2006; Chen et al.
The ca parameter of the Poulovassilis model is related to the shape of the evapotranspiration
In the period from January 2011 to December 2013, the mean value of reference evapotranspiration
for the station of Ariquemes (RO) was 4.03 mm d-1 (standard deviation--s = 0.97 mm [d.sup.-1]), varying from 1.06 mm d-1 in the minimum estimate to 6.76 mm d-1 in the maximum estimate.
(2010), the nature of the spectral behavior of the plants a simple relationship between NDVI and evapotranspiration
can be established by means of stomatal resistance to the transfer of water vapor.
Low flows reflect the minimum peak of precipitation occurring in summer and in the beginning of autumn (August, September, and October) when also evapotranspiration
and water demand for agricultural purposes are the highest.
Rates of water deficit of 0.5 mm [d.sup.-1], evapotranspiration
>50 mm, and degree days >100[degrees]C days promoted the development of the lychee fruits.
One of the advantages of the METRIC model compared to previous surface energy balance-based models for use in arid areas is that it utilizes reference evapotranspiration
([ET.sub.r]) for estimating actual evapotranspiration
([ET.sub.a]) at the cold pixel condition .

into transpiration, soil evaporation, and canopy evaporation in a GCM: impacts on land-atmosphere interaction," Journal of Hydrometeorology, vol.
There were different model inputs including precipitation, seepage through irrigation system, return flow, recharge through water courses and evapotranspiration
were distributed on all the cells of model grid according to their geographic location.
Irrigation was scheduled based on the crop evapotranspiration
(ETc) calculated as follows:
