The article discusses the existing inland water resources in Azerbaijan. As a result of scientific research, it is known that all the rivers of Azerbaijan belong to the Caspian Sea, which is an inland basin, and the number is 8359. Drawing attention to the formation of Azerbaijan's internal water resources, the author notes that these waters were formed over a long geological period, depending on climatic and relief conditions. The article notes that the rivers, which are considered to be the most important element of sand water, are divided into three groups according to the source of food and the direction of flow. It is grouped as a temporary river flowing directly into the Caspian Sea, belonging to the Kura River basin and Absheron-Gobustan. When discussing the reasons for the formation of some rivers, it is shown that the rivers flowing through the area formed canyon-shaped valleys as they passed through the soft, easily washed rocks of the Cretaceous and Jurassic periods of the Mesozoic era. The Tangi gorge, a tributary of the Valvalachay, was formed for this reason. In addition to rivers, natural water resources include lakes. Depending on the natural and geographical conditions of the area where the lakes are located, the origin of the depression, they are subject to various physicochemical and hydrological features. Key words: Azerbaijan, geographical location, water resources, rivers, lakes, river mouth, source of water resources

Southern Caspian Sea

The southern shore of the Caspian Sea is well known for its great potential in relation to sites of Mesolithic date (e.g. Coon 1951; Jayez & Vahdati Nasab 2016). Situated between two major geographic barriers—the Alborz Mountains to the south, and the Caspian Sea to the north—this area has been considered one of the major hominin dispersal corridors during the Pleistocene–Holocene transition (Vahdati Nasab et al. 2013). Furthermore, the relatively stable and mild climatic conditions, vast and lush temperate forests, and abundance of fauna and water resources have all made this region an attractive niche for human settlement.

Economic Implications

The Caspian coast of Azerbaijan is notable for its considerable diversity and complexity, it requires appropriate theoretical and practical work to make the most correct decisions ensuring the proper organization of rural recreational farms and industry of the territory. To successfully conduct agricultural production and increase the area of irrigated land used, along with the study of the land fund, the study of the region’s water resources is of great importance.

Hydrology And Water Resources

Abstract. Precipitation is the main driver of the water balance variability of the water over space and time, and changes in precipitation have very important implications for hydrology and water resources. Variations in precipitation over daily, seasonal, annual, and decadal time scales influence hydrological variability over time in a catchment. Flood frequency is affected by changes in the year-to-year variability in precipitation and by changes in short-term rainfall properties. Desiccation of the Caspian Sea is one of the world's most serious ecosystem catastrophes. The Persian Sturgeon (Acipenser persicus) caught under 10 m depth using bottom trawl net by research vessel during winter 2012, summer and winter 2013 and spring 2014 in east, central and west of southern parts of Caspian Sea, then, their diets were investigated. During 136 trawling in the aimed seasons, Persian sturgeon with 1 to 2 years old and 179.67 × 0.2 g (body weight) and 29.97 ± 0.4 cm (Total length) captured. Examination of stomach contents in the sturgeon specimens revealed that the food spectrum was composed of bony fishes (Neogobius sp., Atherina sp. and Clupeonella delicatula), invertebrates belonging to the family Ampharetidae polychaeta worms including (Hypanai sp. and Nereis diversicolor), various crustaceans (Gammarus sp. and Paramysis sp.). Investigation on stomach contents of sturgeon Acipenser persicus caught under 10 m depth in 2012 to 2013 surveys showed that there is significant difference in the consumed food. The most food diversity have been observed in winter 2013, also Polychaeta is the primary consumed food and crustacean is the secondary one (P > 0.05), no new types of food (such as bony fishes or benthics) have been observed on food chain of Acipenser persicus and shows no significant difference (P > 0.05).

The article contains a geographical analysis of the Concept on the legal status of the Caspian Sea (2018). As the main geographical factors, the author considers: the natural properties of the Caspian Sea, as a geographical object (sea or lake); its natural resources (emphasis is placed on reserves and the territorial distribution of hydrocarbon raw materials and biological resources); the geographical location of the Caspian countries (the continental nature of Kazakhstan, Turkmenistan and Azerbaijan, which forms the dependence of their international economic activity on neighboring countries — Russia, Iran; geographic location of the Caspian Sea (transit — the location at the junction of the Central Asian region, rich in hydrocarbon raw materials and Europe, China, its leading consumers

I will introduce the texts with a few remarks on the geographical location of the provinces where they are found. Kola is a peninsula on the White Sea and part of the government of Archangel which extends along the Artic Sea from Finland to Siberia. Vologda lies south of Archangel, and Perm southeast of Vologda, both on the Siberian frontier. The three governments of Niži-Novgorod (Nižegorod), Vladimir and Tver follow each other (from the city that gives its name to the first) to a point between Moscow and Petersburg. The provinces of Kaluga, Tula, Tambov, Saratov and Astrachan extend from a point a little towards the south west of Moscow to the Northern extremity of the Caspian Sea; Voronež lies south of Tambov.

Shallow Coastal Waters

Shallow coastal waters of the Volga river is a flooded feeding area for fish juveniles of nonmigratory fish species. There takes place annual downstream migration of fluvial anadromous fish species from spawning grounds of the Volga river to the Northern Caspian Sea. The most important factors determining the number and qualitative characteristics of fry fishes are the level of the Caspian Sea (currently having a tendency to the lowering), hydrological and thermal regimes of the Volga river. Researches were carried out in definite periods of time. In the summer-autumn period of 2012 fry fishes were presented by 19 species (13 of them were commercial species), which belonged to 9 families. The article gives data on all the commercial fish species. In the first decade of July the maximum number of fry fish was registered in the western part of the Volga outfall offshore - in box 247 (19.86 mln specimens/km2), in the eastern part - in box 142 (20.4 mln specimens/km2). The most populous were roach, red-eye, silver bream and bream; size-weight characteristics were better in the areas remoted from the Volga delta. In the third decade of July the quantitative indicators of fry fish on these areas decreased, size-weight characteristics greatly increased. In the second decade of October in the western part of the seaside there were registered increased pre-wintering concentrations of fish juveniles, their qualitative indicators increased, which is evidence to favorable feeding conditions in 2012.
