Abstract

The article discusses the main problems of predicting changes in the geological environment under anthropogenic impact: in terms of, changes in the filtration properties of soils in the aeration zone. The value of soil water permeability serves as the basis for calculating the loss of water from the projected canals, irrigation areas, setting the norms and timing of irrigation, calculating and placing the collector-drainage network. The geo-filtration characteristics of the loess soils of the aeration zone were determined by experimental filling into pits, according to field observations on existing drains and by soil locking in experimental pits and laboratory studies. Based on these data, the predicted values of the filtration coefficient of rocks of various genesis and ages were calculated and recommended for calculations.
