2. Case study. The Thessaly plain (figure 1) was selected as the case study due to its importance for the Greek agriculture and is situated in central Greece, in the Pinios river basin, the largest river basin in Greece (area 10 km 2) with mean annual rainfall of mm and mean annual runoff hm 3 ( mm). It constitutes a region of intensive agricultural activity, where Cited by: In the evapotranspiration process, the water is transferred from the soil and plant surfaces into the atmosphere in the form of water vapor. In practice, the estimation of the evapotranspiration rate for a specific crop requires first calculating potential or reference evapotranspiration and then applying the proper crop coefficients (K cCited by:

Remote Sensing of Evapotranspiration Study Area (Blythe, California) Palo Verde Irrigation District Cibola National Wildlife Refuge. SELECTED BIBLIOGRAPHY ON EVAPORATION AND TRANSPIRATION By T. W. ROBINSON and A. I. JOHNSON INTRODUCTION Evaporation to the hydrologist is the process by which water moves as vapor from water or soil surfaces into the atmosphere, and transpiration is the process by which water is discharged into the atmosphere by by: 4.
Evapotranspiration can be defined as the sum of all forms of evaporation plus transpiration, but here at the Water Science School, we'll be defining it as the sum of evaporation from the land surface plus transpiration from plants. Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference. Evapotranspiration is the term used to describe the part of the water cycle which removes liquid water from an area with vegetation and into the atmosphere by the processes of both transpiration and evaporation. Evaporation occurs when liquid water is converted to water vapour and hence removed from a surface, such as a lake, soil or wet.

Evapotranspiration (ET) is an important component of the hydrologic budget because it expresses the exchange of mass and energy between the soil-water-vegetation system and the atmosphere.
Stanhill, in Encyclopedia of Soils in the Environment, Development of the Concept ‘ Evapotranspiration,’ both actual and potential, was first defined by Thornthwaite inand the term became widely known and used following his publication in which potential evapotranspiration was calculated as a complex empirical function of air temperature and day length.

[ EVAPO(RATION) + TRANSPIRATION] the total water loss from the soil, including that by direct evaporation and that by transpiration from the surfaces of plants.
Evaporation of water is a critical environment process. Evaporation is the physical process of converting liquid water into vapor and the release of large amounts of energy during this conversion process.
Evapotranspiration (ET) can be determined through either direct or indirect measurements. There is a lot happening about evapotranspiration (ET) at the moment, and during I will be involved in several activities related to evapotranspiration measurement and theory (see this basic USGS page about ET, where I also got the image left).
See this GEWEX article (p.5) from March entitled "Current Challenges in Evapotranspiration Determination" I've co-authored about ET.
Evapotranspiration (ET) is a term used to quantify all evaporative losses in a watershed. 1) Evaporation of water intercepted and stored by vegetation 2) Water transpired by vegetation 3) Water evaporated from soil. ET accounts for about 60 to 70% of the water loss from a slope.

Reference crop ET, or reference evapotranspiration (E ref), addresses some of the ambiguities associated with definitions for potential ET and serves as a consistent climatic index for most common method of estimating E or ET is estimating the energy available for E or ET.
Evapotranspiration The sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. studies require some insight of the magnitude of the evapotranspiration component.
Many other factors relating to these needs have been mapped successfully on a regional scale. For example, maps are available for temperature, precipitation, humidity, sunshine, runoff, radiation, evaporation from free water surfaces and other Size: 2MB.
Distinctions are made (Figure 4) between reference crop evapotranspiration (ET o), crop evapotranspiration under standard conditions (ET c) and crop evapotranspiration under non-standard conditions (ET c adj).ET o is a climatic parameter expressing the evaporation power of the atmosphere.
ET c refers to the evapotranspiration from excellently managed, large, well-watered fields that. Purchase Evapotranspiration from Plant Communities, Volume 13 - 1st Edition.

Stormwater management applications may include water surfaces (e.g., pond, wetland, etc.), vegetation, or both, and therefore may require an estimation of evaporation, transpiration, or both to estimate water level.
