The process of how soil moisture profiles evolve into the and reach root zone could be estimated by solving appropriate strong nonlinear Richards’ equation. nonlinearity equation occurs because diffusivity D is generally an exponential function water content. In this work, boundary conditions physical problem are considered fuzzy for various reasons (e.g., machine impression, human errors, etc....

Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...
