A Framework for Monitoring Soil Hydraulic Properties of Undisturbed Soil Samples and Modeling Unsaturated Zone Water Flow

by Efthymios Chrysanthopoulos, Andreas Kallioras Environ. Process. 12, 47 (2025). https://doi.org/10.1007/s40710-025-00791-1 Abstract Soil structure is the predominant factor of water, gases, and nutrients movement within the unsaturated zone. Despite the growing interest in the influence of structured soil media on soil-water dynamics, there is a gap in explicit technical documentation

Temporal and geographic extrapolation of soil moisture using machine learning algorithms

by Efthymios Chrysanthopoulos, Andreas Kallioras CATENA, 257, 109156. https://doi.org/10.1016/j.catena.2025.109156 Abstract The inherent characteristic of machine learning algorithms to extrapolate when the convex hull is expanded with new unseen instances, can be exploited in soil moisture prediction, concerning temporal and geographic extrapolation. This study describes the implementation of a machine learning

Unveiling the Non-Market Value of a Fragile Coastal Wetland: A CVM Approach in the Amvrakikos Gulf, Greece

by Dimitra Pappa, Dimitris Kaliampakos Environments 2025, 12(2), 59; https://doi.org/10.3390/environments12020059 Abstract Wetlands are highly productive ecosystems with multidimensional value and significant social and economic impacts. Estimating the economic value of their non-marketed goods and services—benefits not traded in conventional markets—can provide essential insights to guide protection, restoration, and sustainable management
