Simulation Study of Soil Infiltration Process Based on an Improved Mathematical Model

This work refined the current mathematical model and thoroughly examined the process of deep water infiltration into the soil, which is seen as a result of irrigation operations on agricultural lands under irrigation and precipitation conditions. According to research findings, irrigation and precipitation have a substantial impact on the moisture content of the top one meter of soil. Water absorption into the soil is accelerated by irrigation water, which creates comparatively stable infiltration channels in the topsoil layer. As a result, there is an increase in moisture content in the lower layers, which are deeper than one meter, and the transfer of moisture to these layers becomes more intense. In turn, maintaining a high soil moisture content can be crucial to guaranteeing the agro-ecosystem's stability in the face of shifting climatic conditions.
