Numerical modeling of groundwater filtration in irrigated areas
Keywords:
concentration, groundwater level, saturation, filtration rate, pressure change, temperature, irrigation waterAbstract
The article covers the theoretical and practical aspects of the mathematical model for predicting the movement and level of underground water based on the studied literature. An improved mathematical model based on Darcy’s law and convection-diffusion equations are presented for predicting the movement and level of groundwater in cropland. The model allows determining the speed and concentration of underground water, taking into account the processes of convection and diffusion of water. In addition, as a new approach, taking into account water salinity, temperature and soil saturation in calculating the permeability coefficient, which forms the distribution of water in the environment increased the efficiency of the model. Effective management of irrigation systems and saving of water resources can be achieved by using the model.
