Energy Distribution Characteristics and Environmental Impact Factors in Different Regions of the Summer Monsoon Transition Zone

Frontiers in Environmental Science, 2022
The summer monsoon transitional zone is a typical transitional ecosystem that is, also ecologically fragile. It is critical to explore the land surface energy balance and the water and heat transfer processes in this region for water resource management.

Evapotranspiration of riparian ecosystems and irrigated cotton agriculture at the middle reaches of the Tarim River, Xinjiang, China

Central Asian Journal of Water Research, 2017
In the steppes, semi-deserts, and deserts of Central Asia the most productive ecosystems are riparian ecosystems like forests and shrublands. Rivers also serve as the water source for irrigation so that the major settlements and oases of the region are ...

Actual evapotranspiration from partially tile-drained fields as influenced by soil properties, terrain and crop

Soil and Water Research, 2011
Physical properties of soils have a significant influence on their water regime and should be considered when selecting suitable agricultural crops for particular sites, taking into account the crop productivity and its water requirements.

Surface energy fluxes in wheat (Triticum aestivum L.) under irrigated ecosystem

Journal of Agrometeorology, 2012
The surface energy fluxes were measured over irrigated wheat during winter season. 2008-09 and 2009-10 sown on first week of November. Study revealed that the net radiation flux (Rn) varied from 420 to 693 was during 2008-09 and 328 to 926 W m-2 during ...

Uncertainty analysis of computational methods for deriving sensible heat flux values from scintillometer measurements [PDF]

Atmospheric Measurement Techniques, 2009
The use of scintillometers to determine sensible heat fluxes is now common in studies of land-atmosphere interactions. The main interest in these instruments is due to their ability to quantify energy distributions at the landscape scale, as they can ...

Impact of differently designed bare soil evaporation schemes on variability of Bowen ratio and ground temperature in land-air parameterization modeling

Meteorologische Zeitschrift, 1994
The correct partitioning of the energy between the sensible and latent heat fluxes at the bare soil and computing its ground temperature is very important in designing the surface scheme for modeling the processes in the land-air exchange. However, using

Estimation of evapotranspiration using Bowen ratio method

IFAC-PapersOnLine, 2018
Abstract Evapotranspiration (ET) or water loss to the atmosphere is one of the most significant parts of the hydrologic cycle, and its estimation is subjected to uncertainties. Therefore, Calculation of the ET is an integral part of agricultural water management in local, regional and global water balance studies.
