Inland waters are all reservoirs and other water reserves located in the territory of a particular country. It can be not only rivers and lakes located inland, but also part of the sea or ocean, in the immediate vicinity of the state border.
A river is a stream of water moving for a long time along a certain channel. Most rivers flow constantly, but some can dry out during the hot summer months. In this case, their channel resembles a sand or earthen gutter, which is again filled with water with a decrease in air temperature and heavy rain.
Any river flows where there is a slope. This explains the very intricate shape of some channels that constantly change direction. A stream of water sooner or later flows into another river, or into a lake, sea, ocean.
It is a natural body of water located in the deepening of the earth's crust or mountain fault. The main specificity of the lakes is the lack of their connection with the ocean. As a rule, lakes are replenished either due to the flowing rivers, or thanks to springs spouting from the bottom. Also, a fairly stable composition of water refers to the features. It is “fixed” due to the absence of significant currents and a small influx of new waters.
A canal is an artificial channel filled with water. Such structures are built by a person to achieve a specific goal, for example, supplying water to arid areas or organizing a shorter transport route. Also, the channel can be overflow. In this case, it is used when overflowing the main reservoir. When the water level rises above the critical level, it flows through an artificial channel to another place (often to another body of water located below), as a result of which the probability of flooding the coastal zone disappears.
Wetlands are also inland waters. It is believed that the first swamps on Earth appeared about 400 million years ago. Such water bodies are characterized by rotting algae, released hydrogen sulfide, the presence of a large number of mosquitoes and other features
A glacier is a huge amount of water in an ice state. This is not a body of water, however, also applies to inland waters. There are two types of glaciers: integumentary and mountain. The first type is ice, covering a vast area of the earth's surface. It is common in the northern territories, for example, Greenland. The mountain glacier is characterized by a vertical orientation. It’s kind of a mountain of ice. A peculiar kind of mountain glacier are icebergs. True, they are difficult to classify as inland waters due to the constant movement across the ocean.
Inland waters include not only water bodies, but also underground water supplies. They are divided into many types, depending on the depth. Underground water storages are widely used for drinking purposes, since in most cases it is very clean water, often having a healing effect.
Sea and ocean waters
This group includes the territory of the sea or ocean adjacent to the coastline of the land within the state border of the country. Here are the bays, to which the following rule applies: it is necessary that all coasts of the gulf belong to one state, and the width of the water surface should not exceed 24 nautical miles. Marine inland waters also include port water areas and strait channels for the passage of ships.
