Estimation of evapotranspiration (ET) parameters is essential for understanding crop water requirements and to find out the ground water recharge. In situ data collection procedures are generally adop...
Satellite based earth observation (EO) platforms have proved capability to spatio-temporally monitor changes on the earth's surface. Long term satellite missions have provided huge repository of optic...
Actual Evapotranspiration (ETa) is one of the most useful indicators to explain whether the water is being used asintended”. ETa variations, both in space and time and from different land use typesa...
Evapotranspiration(ET) is one of the key fluxes in all water budget studies, satellite remote sensing is a promising tool to establishment operational frame works for estimating ET at large extent. On...
Three-temperatures model (3T model) was a recently proposed algorithm, which could be used to estimate actual evapotranspiration (ET) and evaluate environmental quality. The key parameters included ar...
Understanding and mitigating against the impact of land use change and groundwater extraction on groundwater dependant ecosystems (GDE) requires information on the distribution and environmental water...
Energy and mass transport between and within soils, canopies, and the atmosphere is an area of increasing interest in hydrology and meteorology. Evapotranspiration (ET) can account for over 90% of th...
Potential evapotranspiration (PET) is an important parameter of water budgets at different spatial scales and is a critical variable for understanding regional biological processes. It is often an i...
In this study Landsat Enhanced Thematic Mapper Plus (ETM+) images (Row/Path:173/50) acquired on September 6, 2001 and November 28, 2002 were analyzed together with the aid of additional ancillary data...
Evapotranspiration (ET) plays a significant role in regional and global climates through its partitioning in hydrological cycles, and its estimation is thus of a great importance in assessing ground...
FIELD EVAPOTRANSPIRATION ESTIMATION IN CENTRAL LUZON, PHILIPPINES USING DIFFERENT SENSORS: LANDSAT 7 ETM+, TERRA MODIS AND ASTER.
The present study aimed to measure the distribution of water loss via evapotranspiration (ET) in a pistachio tree orchard under drip irrigation and non-irrigation conditions at the experimental orchar...
Water consumption has been exceeding as the world population increases. Therefore, it is very important to manage water resources with care as it is not an endless resource. The Water loss in regional...
A Bayesian method was used to fit the Shuttleworth–Wallace model to half-hourly measurements ofevapotranspiration (ET) with the eddy covariance technique from an alpine grassland on the Qinghai-Tibeta...
以土壤-水分-大气-作物系统模拟模型——SWAP模型和FAO-56分册推荐的最新双作物系数法为基础,计算浑善达克沙地天然植被蒸散量。结果表明:SWAP模型和最新双作物系数法模拟的蒸散量结果相近,均可用于模拟蒸散量。SWAP模型能模拟土壤剖面的水分动态。
