Evaluation and comparison of OpenET models for estimating soil water depletion of irrigated alfalfa in Arizona

Agricultural Water Management
Growers in arid regions often estimate soil water depletion (Dr) of the root zone in making irrigation scheduling decisions. While growers might use soil water sensors, actual Dr in fields may be only vaguely assessed.

Unravelling Regional Water Balance Dynamics in Anthropogenically Shaped Lowlands: A Data‐Driven Approach

Hydrological Processes, Volume 39, Issue 1, January 2025.
This study examines the impacts of anthropogenic activities and natural factors on water resources in the Lusatia region, a lowland area in northern Germany. Using ground‐based and remote sensing data and principal component analysis, the research identified key drivers of groundwater, surface water and evapotranspiration dynamics over 30 years.

Comparing Cotton ET Data from a Satellite Platform, In Situ Sensor, and Soil Water Balance Method in Arizona

Agriculture
Crop production in the desert Southwest of the United States, as well as in other arid and semi-arid regions, requires tools that provide accurate crop evapotranspiration (ET) estimates to support efficient irrigation management.

Multi‐Satellite Data Assimilation for Large‐Scale Hydrological‐Hydrodynamic Prediction: Proof of Concept in the Amazon Basin

Water Resources Research, Volume 60, Issue 8, August 2024.
Abstract Satellite remote sensing enhances model predictions by providing insights into terrestrial and hydrological processes. While data assimilation techniques have proven promising, there is a lack of standardized and effective approaches for integrating multiple observations simultaneously.

Estimating agricultural irrigation water consumption for the High Plains aquifer region with integrated energy- and water-balance evapotranspiration modeling approaches

Agricultural Water Management
Estimation of irrigation water use provides essential information for the management and conservation of agricultural water resources. Conventionally, water use data are created based on reports and surveys from water users, whereas manual records may ...

Characterizing Crop Water Use Dynamics in the Central Valley of California Using Landsat-Derived Evapotranspiration

Remote Sensing, 2019
Understanding how different crops use water over time is essential for planning and managing water allocation, water rights, and agricultural production. The main objective of this paper is to characterize the spatiotemporal dynamics of crop water use in

IRRIGATION IN THE WESTERN UNITED STATES: OCCURRENCE, IMPACTS, AND SUSTAINABILITY [PDF]

, 2023
Irrigation represents our greatest intervention in the hydrological cycle, accounting for over 80% of extracted freshwater in the Western U.S. Despite its economic and ecological importance, irrigation’s spatial and temporal occurrence, magnitude ...

Modeling the Effects of Artificial Drainage on Agriculture‐Dominated Watersheds Using a Fully Distributed Integrated Hydrology Model

Water Resources Research, Volume 60, Issue 6, June 2024.
Abstract In agriculture‐dominated watersheds where natural drainage is poor, agricultural ditches (narrow engineered channels) and tile drains (perforated pipes) are widely employed to enhance surface and subsurface drainage, respectively. Despite their relatively small scale, these features exert substantial control over the hydro‐biogeochemical ...

Irrigation response to drought in the Western United States, 1987–2021

JAWRA Journal of the American Water Resources Association, Volume 60, Issue 2, Page 603-619, April 2024.
Abstract The Western United States (U.S.) relies heavily on scarce water resources for both ecological services and irrigation. However, the response of irrigation water use during drought is not well documented. Irrigation decision‐making is complex and influenced by human and environmental factors such as water deliveries, crop yields, equipment ...

Enhancing hydrological model calibration through hybrid strategies in data‐scarce regions

Hydrological Processes, Volume 38, Issue 2, February 2024.
Hybrid approach by integrating remote sensing datasets along with field measured river bathymetry data to estimate the river discharge to calibrate the Soil and Water Assessment Tool (SWAT) model can be used for the streams with narrow width. Calibration based on (i) stage‐discharge curve using spatial proximity approach and (ii) water level and river ...
