Water retention of rigid soils from a two-factor model for clay [PDF]
The Open Transport Phenomena Journal 2 (2010) 90-102, 2014 Water retention is one of the key soil characteristics. Available models of soil water retention relate to the curve-fitting type. The objective of this work is to suggest a physical model of water retention (drying branch) for soils with a rigid matrix.

Natural evaporation from open water, bare soil and grass
Proceedings of the Royal Society of London. Series A, Mathematical and physical sciences, 1948 Two theoretical approaches to evaporation from saturated surfaces are outlined, the first being on an aerodynamic basis in which evaporation is regarded as due to turbulent transport of vapour by a process of eddy diffusion, and the second being on an ...

Investigating the potentialities of Monte Carlo simulation for assessing soil water content via proximal gamma-ray spectroscopy [PDF]
Journal of Environmental Radioactivity 192, 105-116, 2018, 2018 Proximal gamma-ray spectroscopy recently emerged as a promising technique for non-stop monitoring of soil water content with possible applications in the field of precision farming. The potentialities of the method are investigated by means of Monte Carlo simulations applied to the reconstruction of gamma-ray spectra collected by a NaI scintillation ...

Robotic Irrigation Water Management: Estimating Soil Moisture Content by Feel and Appearance [PDF]
arXiv, 2022 In this paper we propose a robotic system for Irrigation Water Management (IWM) in a structured robotic greenhouse environment. A commercially available robotic manipulator is equipped with an RGB-D camera and a soil moisture sensor. The two are used to automate the procedure known as "feel and appearance method", which is a way of monitoring soil ...
