MODERN CONDITIONS OF NUTRITION AND FORMATION OF GROUNDWATER RESOURCES OF THE KARAKALPAK USTYURT

The article discusses the modern conditions of nutrition and formation of groundwater resources of the Karakalpak Ustyurt. Numerous hydrogeological studies have found out that in the areas of depressions as a result of transit runoff formed outside the study area, as well as in weakened zones along regional faults traced in the vaulted parts of the meganticlines of the Central Ustyurt uplift system, natural funnels with a relative depth of up to 15-30 m were formed as a result of groundwater discharge. In arid conditions, with a meager amount of precipitation, groundwater of upper Pliocene-Quaternary formations are formed mainly in low relief forms such as flat depressions, steppe saucers, large gullies, valleys of temporary streams, where during the period of snowmelt and heavy heavy rains, a large mass of atmospheric infiltration water is collected from a significantly spillway area. In this case, in these territories, groundwater is formed in the form of lenses of different sizes depending on the size of the area and, accordingly, they have a complex system of connection between each other.
