History and Progress of Developing Basal Crop Coefficients for Estimating Crop Evapotranspiration
International Journal of Agronomy, Volume 2025, Issue 1, 2025.Efficient agricultural water management relies on accurate estimates of crop water use. A key component of this is quantifying evapotranspiration (ET), the combined process of evaporation of water through soil evaporation (E) and plant transpiration (T), which varies with weather, crop type, and management.

Water Resources Research, Volume 60, Issue 10, October 2024.Abstract Vegetation‐related processes, such as evapotranspiration (ET), irrigation water withdrawal, and groundwater recharge, are influencing surface water (SW)—groundwater (GW) interaction in irrigation districts. Meanwhile, conventional numerical models of SW‐GW interaction are not developed based on satellite‐based observations of vegetation ...

Water Resources Research, Volume 60, Issue 4, April 2024.Abstract This study developed and evaluated 30‐m daily evapotranspiration (ET) estimates using the Priestley‐Taylor Jet Propulsion Laboratory (PT‐JPL) model with ECOSTRESS, Moderate MODIS, harmonized Landsat Sentinel‐2 (HLS) imagery, ERA5‐Land reanalysis, and eddy covariance measurements. The new daily 30‐m ET showed significantly improved performance (

Land Data Assimilation: Harmonizing Theory and Data in Land Surface Process Studies
Reviews of Geophysics, Volume 62, Issue 1, March 2024.Abstract Data assimilation plays a dual role in advancing the “scientific” understanding and serving as an “engineering tool” for the Earth system sciences. Land data assimilation (LDA) has evolved into a distinct discipline within geophysics, facilitating the harmonization of theory and data and allowing land models and observations to complement and ...

Water Resources Research, Volume 60, Issue 3, March 2024.Abstract Current irrigation water use (IWU) estimation methods confront uncertainties warranting further attention, primarily stemming from constraints within model structure and data quality. This study proposes a hybrid framework that integrates multiple machine learning (ML) methods with theory‐guided strategies to calculate IWU for three principal ...

Radiation balance and urban land use (case study: Kermanshah city) [PDF]
تحقیقات کاربردی علوم جغرافیایی, 2019 Population growth and urbanization development are the main triggering factors of changes in urban land uses. These, in turn, result in changes in the components of radiation balance.
