Abstract: In the field of soil hydrology, the Richards equation is commonly used to model water flow in unsaturated soils. The high nonlinearity of the Richards equation makes it very challenging to solve analytically for situations ...

Abstract: The importance of discharge measurements is fully acknowledged in many research fields, mostly in hydrology. Numerous measurement devices and various overflow structures have been proposed for discharge measurements; ...

Abstract: In surface and subsurface drip irrigation systems, predicting the size expansion of the wetting bulb and the irrigation time is mandatory for water saving, and helps drive their design and scheduling, which cannot ignore ...

Abstract: The study of generation process of subsurface stormflow, typical of well-drained and high-permeable soils, can be theoretically carried out by applying the continuity and motion equations with the appropriate boundary ...

Abstract: Microirrigation plants, if properly designed, allow water use efficiency to be optimized and quite high values of emission uniformity to be obtained in the field. It is known that disposing paired laterals, in which two ...

Abstract: Every model is, by definition, a simplification of the system under investigation. Although it would be desirable to reduce the gap between the simulated and the observed behaviors of the system to zero, this reduction is ...
