A strategy for quantitative analysis of mono- and polysystemic organization of multi-level geospaces is described, with the construction of a series of empirical models of inter-component and inter-complex connections. The “micro-” and “macrosubstrate” approaches to the structural and functional analysis of the state of the natural environment are combined. As a methodological basis, a provision on the structural levels of natural-territorial organization is proposed, based on the conceptual cybernetic model of the natural complex as a hierarchical control system. A cybernetic model of the natural complex has been created as a hierarchical control system; the model has enriched modern ideas about the mechanisms and structural  levels  of  the  spatial  organization of  the natural environment. Model has enriched modern ideas about the mechanisms and structural levels of the spatial organization of the natural environment. An experiment was performed in order to analysis the state of geographical spaces by three  blocks of cybernetic model: landscape frame, processor, and landscape pattern.  Based on this model, a system of conjugation of different-level characteristics of natural components with the taxonomic rank of geographic spaces (from the geographical sector and natural zone to landscape facies and biogeocoenosis) was constructed. Using the Volga River basin as an example, a comparative assessment of environmental factors in their landscape-forming influence was carried out.

The main aim of groundwater studies is to assess the physical and chemical characterizations of water-bearing layers as a goal for assessing their suitability for various purposes Wasit Governorate, which is located in eastern Iraq, is an important area in terms of agriculture and poultry and livestock husbandry. The area mainly depends on groundwater, especially on the Iraqi-Iranian border. The area was investigated (40) wells inventoried during the field study and used to demonstrate the hydrogeological and hydrochemical properties. The groundwater aquifer is composed of Quaternary deposits and Mukdadiyah formation. The mean thickness, transmissivity, and maximum yields were 53 meters, 114 m²/day, and 600 m³/day, respectively. The groundwater moved partially to the western parts and mainly towards the southern parts of the area towards Shuwaicha Marsh, which is located outside the study area. The salinity map showed a regular decrease in salinity concentrations towards the central and southwestern parts of the area due to groundwater recharge from infiltrated surface water. The groundwater is brackish to saline, with two dominant calcium and sodium sulphate types. The central area between Zurbatia and Badra towns can be a qualified location to increase well drilling due to salinity decreasing as the transmissivity and maximum yields increase.
