Potential Evapotranspiration in Merapi Aquifer System

Sustainability (STPP) Theory, Practice and Policy, 2023
Temperature variation due to climate change can give greatest impact on potential evapotranspiration. Increase of temperature in Yogyakarta Special Region can increase potential evapotranspiration. It is necessary to study potential evapotranspiration as one of indication impact of climate change to its potential evapotranspiration.

Modelling potential evapotranspiration of potential vegetation

Ecological Modelling, 1999
Abstract A method to estimate the potential evapotranspiration (PET) rate of potential vegetation is presented. The method is based on the Penman–Monteith equation which includes fixed parameters and the variables vegetation height and leaf area index (LAI).

A Simple Apparatus for Measuring Potential Evapotranspiration

Nature, 1952
THE combined process of evaporation from the soil and transpiration from plants is known as ‘evapotranspiration’. The amount of moisture so used varies from place to place and depends mainly on climate (especially temperature and precipitation) and the closeness of the vegetative cover.

Maximum Potential Evapotranspiration Frequency

Journal of the Irrigation and Drainage Division, 1972
Maximum 1-day, 3-day, 7-day, 15-day, and monthly values of evapotranspiration as measured by a lysimeter, ET M , and potential evapotranspiration as estimated by computed lake evaporation E L were found to be log-normally distributed. Equations were developed to estimate the two parameters of this distribution for both ET M and E L for any duration ...

Daily potential evapotranspiration modelling

Agricultural Water Management, 1988
Abstract The paper is concerned with a stochastic procedure for generating evapotranspiration. The procedure consists of two steps: the sequence of four different types of day in relation to rainfall occurrence is obtained by a two-state, first-order Markov chain model; and the daily potential evapotranspiration is generated for each type of day by ...

Alternate corrections for estimating actual wetland evapotranspiration from potential evapotranspiration

Wetlands, 2006
Corrections can be used to estimate actual wetland evapotranspiration (AET) from potential evapotranspiration (PET) as a means to define the hydrology of wetland areas. Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios.

THORNTHWAITE'S POTENTIAL EVAPOTRANSPIRATION TERM

Canadian Geographies / Géographies canadiennes, 1965
RÉSUMÉVu que la formule empirique de Thornthwaite pour évaluer l'évapotranspiration potentielle se manipule bien, elle semble avoir une base théorique latente. Ce concept se rapporte à un état d'équilibre dans le mouvement vertical de vapeur d'eau atmosphérique et, ainsi, le transport par mètre de hauteur est invariable dans les couches inférieures ...

Potential Evapotranspiration in Arid Regions

Journal of Applied Meteorology, 1964
Abstract The concept of potential evapotranspiration, as applied to arid regions, is examined using an energy balance approach suggested by Budyko. Using data for Yuma, Ariz., it is shown that a 50 per cent increase in the relative humidity of the air above an irrigated field is accompanied by a 10 to 15 per cent decrease in potential ...

Potential evapotranspiration at Simcoe, Southern Ontario

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1968
Several approaches to the evaluation of potential evapotranspiration (PE) are discussed from the point of view of the energy balance equation. Hourly and daily PE were evaluated for an irrigated ryegrass site near Simcoe in Southern Ontario during the summer of 1967 using the Bowen ratio and Penman solution of the energy balance equation, Thornthwaite ...
