One of the most important natural resources we have is the soil and it is of great interest to the society to take care of them and not to pollute it. In the study of this issue, we are going to consider one of the most common forms of soil contamination ... see more

Hydrus-2D/3D is a numerical software to simulate water and solute movement in porous media. Currently, three different versions of the Hydrus software packages are available: Hydrus-1D, Hydrus-2D, and Hydrus (2D/3D). Similar basic processes are involved o... see more

Aim of study: The aim of the present study was to introduce a sinusoidal equation into poultry science by applying it to temporal growth data from quail.Material and methods: To examine the performance of the sinusoidal equation in describing the growth p... see more

Mosaic 3-D cascade of parallelepiped-shaped silt blocks, which sandwich sand- lled cracks, has been discovered in the eld and tested in lab experiments. Controlled wetting-drying of these blocks, collected from a dam reservoir, mimics field ponding-desicc... see more

Why soil water diffusivity in stead of hydraulic conductivity? In order to simplify the mathematical treatment of unsaturated flow process the scientists transformed the classical Richard equation into a diffusion equation that is easier to solve under a ... see more

In this note we make a connection between diffusion equation and equations of Darcy andRichard used in study the soil hydrodynamics.

A solitary wave in two-dimensional, incompressible, turbulent free-surface flow over a plane bottom with small, constant slope is considered. The flow is assumed to be slightly supercritical with Froude numbers close to 1. If the flow far upstream and far... see more

This paper presents several algorithms that were implemented in DRUtES [1], a new open source project. DRUtES is a finite element solver for coupled nonlinear parabolic problems, namely the Richards equation with the dual porosity approach (modeling the f... see more
