Regional distribution patterns of soils in delta ecosystems and their potential use on different continents

New approaches using mathematical methods have been developed for estimation of the effect of undrained plain heights in delta ecosystems on soil diversity. This makes it possible to consider the effect of positive elements in the delta plain located below the zero marks that favoring the formation of local drainage. Models have been developed from the height gradients of the Terek–Kuma Lowland by the least squares method. The proposed method has revealed the soil diversity and spatial parameters characteristic of alluvialdelta coastal plains common to different continents.
