Multiobjective Simulation–Optimization of Crop Allocation and Water Resources in Canal Command Areas Using Genetic Algorithms

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...

Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Rivoluzioni Matematiche: Teorema del Limite Centrale

open access: yes, 2023
Insieme al teorema dimostrato da Bernoulli nel 1713 e noto oggi come legge dei grandi numeri, il teorema del limite centrale è alla base della statistica inferenziale, che si propone di ricavare informazioni e di trarre conclusioni su una popolazione a ...

A Holistic Assessment of Water Footprint and Irrigation Performance Indicators With Respect to Agricultural Water Productivity

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Global warming has intensified prolonged droughts in many regions, including Türkiye, resulting in growing pressure on already limited water resources. Agriculture, as the largest water‐consuming sector, faces critical challenges in sustaining productivity under increasing water scarcity. In this context, assessing water use efficiency through

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.
