A composite method for estimating annual actual evapotranspiration [PDF]

open access: yesHydrological Sciences Journal, 1988
Abstract There are two ways which can be used to estimate annual actual evapotranspiration, one being an indirect estimation method using the water balance of a catchment, the other being the use of evaporation pan data or climatic data. The method in this paper belongs to the second type.

Assessing plant water status: Part 1 – Classical methods

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

Remote sensing estimation on regional continuous daily evapotranspiration based on Richards equation

open access: yesShuiwen dizhi gongcheng dizhi
Evapotranspiration (ET) is an important part of water cycle in nature, and the estimation of evapotranspiration on spatio-temporal scale has always been a hot issue. Remote sensing can estimate evapotranspiration on regional scale, but it is difficult to

Estimation of Evapotranspiration ETc and Crop Coefficient Kc of Wheat, in south Nile Delta of Egypt Using integrated FAO-56 approach and remote sensing data

open access: yesEgyptian Journal of Remote Sensing and Space Sciences, 2012
Crop water requirements are represented by the actual crop evapotranspiration. Estimation of crop evapotranspiration (ETc) and crop coefficient using remote-sensing data is essential for planning the irrigation water use in arid and semiarid regions ...

An analysis of actual evapotranspiration

open access: yes
The main interacting factors determining the actual evapotranspiration from crops were analysed.The apparent diffusion resistance of the crop was introduced because of the geometry of the evaporative surface. Its relation to light intensity and to suction in the leaves had been estimated for grass.The precipitation intercepted by the crop increased ...

ACTUAL EVAPOTRANSPIRATION IN RELATION TO LEAF AREA

open access: yesHydrology Research, 1974
The ratio of leaf area to ground area required for maintaining potential evaporation has been studied in a 4-year investigation, and the influence of leaf area index on the water use and the actual water balance is discussed.

The Relationship Between Human Activities and Ecosystem Service Supply–Demand From the Perspective of Land Use Transformation

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The equilibrium between ecosystem service supply and demand relationships (ESSDR) is essential for regional sustainable development. Understanding the relationship between human activity intensity (HAI) and ESSDR from the perspective of land use transformation (LT) is important for ecological management and governance.

Cropland Suitability–Use Mismatches and Differentiated Zoning Regulation in the North China Plain: Implications for Spatially Optimised and Sustainable Land Use

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Cropland distribution is often shaped by historical cultivation patterns rather than natural suitability, leading to mismatches between actual land use and agricultural production potential. However, their extent and spatial characteristics remain insufficiently understood in the North China Plain, one of China's most important grain‐producing
