Comprehensive development of the Volga River basin, climate of the Volga River basin

The construction of a canal in the Volga River basin connected the surrounding sea.

Is there any mistake, why don't you talk about the comprehensive development of the Yangtze River, the comprehensive development of the Songhua River, and care about Russia's economic problems. Cut.

Most of the Volga River basin has a continental climate, and the upper, middle and lower reaches of the basin and the right bank of the lower reaches belong to the forest climate.

The lower left bank has a steppe climate and a semi-desert climate;

The temperature and precipitation in the western part of the Volga River were the highest in July, while the precipitation in autumn decreased, but the number of rainfall days increased, and the relative humidity of air leakage was high in autumn and winter.

The average monthly temperature in the eastern part of the basin is much lower than that in the western part of the basin in winter, while the summer temperature is higher.

The Volga River is the longest river in Europe, with a total length of 3,690 kilometers and a basin area of 1.38 million square kilometers. The annual runoff is 254 billion cubic meters, and the seasonal variation is large, because the Volga River water source is dominated by snowmelt, so the spring flow is the largest, accounting for about 60% of the total annual flow, about 20% in summer, and in winter. About 10%.

The drop of the whole river is very small, so the water flow is slow and steady, the river channel is curved, the navigation conditions are very good, the tributary navigation mileage is 3260 kilometers, and the navigation period is more than 200 days.

The Volga River basin is rich in minerals such as oil, natural gas, potash, and phosphorus, as well as natural resources such as building materials and fish, which has become an important factor in the comprehensive development of the basin.

The Volga River basin is located in the central part of the Russian plain and slopes from west to south, with slight uplifts in the north and west. To the north and northwest, there are a large number of lakes scattered in the area of ancient glaciation, generally not large, the largest of which are the White Lake and the Schelliger Lake. The basin is bounded by the Baltic Sea, the White Sea and the Barents Sea basins to the north, the Ural Mountains and the Kara Sea basins to the northeast and east, the Ural River basin to the southeast, and the Dnieper River and the Don River basin to the west and southwest.

The longest inland river in the world is the Volga, the main topographic area through which it flows is the Eastern European Plain, the Caspian Sea is the water area of Xunzaodong, and the river is the mother river of Russia

Therefore, d

The Volga River is an endorheic river, and it flows into the Caspian Sea - the largest saltwater lake in the world, due to the construction of a large number of Volga dams, the amount of water flowing into the Caspian Sea in the Ridge Hall is reduced, the level of the Caspian Sea drops, and the original part of the lake bottom near the delta will be exposed to form a new delta, so the estuary Sanshen Hidden Horn Island advances to the center of the lake, a right. The massive construction of dams will only destroy the river's ecosystem, b wrong.

Answer: A Estuarine delta advances to the center of the lake
