Effect Of Water Stresson Trend Changesof Leaf Proline, Total Soluble Sugars, Relative Water Content and Soluble Protein of Two Species of Pot Marigold

Majallah-i ̒Ulum-i Bāghbānī, 2017
Background and objectives: Water stress is one of the most important environmental stresses in agriculture and urban landscape management. Water stress has been defined as the induction of turgor pressure below the maximal potential pressure.

Assessing Crop Coefficients for Natural Vegetated Areas Using Satellite Data and Eddy Covariance Stations

Sensors, 2017
The Food and Agricultural Organization (FAO) method for potential evapotranspiration assessment is based on the crop coefficient, which allows one to relate the reference evapotranspiration of well irrigated grass to the potential evapotranspiration of ...

Multi-decadal trends in global terrestrial evapotranspiration and its components [PDF]

, 2016
Evapotranspiration (ET) is the process by which liquid water becomes water vapor and energetically this accounts for much of incoming solar radiation. If this ET did not occur temperatures would be higher, so understanding ET trends is crucial to predict

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Long-Term Variability in Potential Evapotranspiration, Water Availability and Drought under Climate Change Scenarios in the Awash River Basin, Ethiopia

Atmosphere, 2020
Understanding the hydrological processes of a watershed in response to climate change is vital to the establishment of sustainable environmental management strategies. This study aimed to evaluate the variability of potential evapotranspiration (PET) and

Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]

, 2020
The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

Agrivoltaics Over Berries in Chile: Potential for Clean Energy Generation and Climate Change Adaption

AgriVoltaics Conference Proceedings
Agrivoltaics (AV), the concept of installing photovoltaic (PV) panels on agricultural land, enabling a dual use of the surface, has the potential to foster renewable energy expansion without land use conflict and to protect water from evapotranspiration.

A Comprehensive Study on Factors Affecting the Calibration of Potential Evapotranspiration Derived from the Thornthwaite Model

Remote Sensing, 2022
Potential evapotranspiration (PET) is generally estimated using empirical models; thus, how to improve PET estimation accuracy has received widespread attention in recent years.
