The river could have lots of rocks and heavy currents
A waterfall or dam blocks their route on the river.
Carrying cargo by ship was faster, easier, cheaper and less dangerous than carrying it by land.

The sea route between Mecca and Aden is generally shorter than the land route. The sea route involves traveling across the Red Sea, while the land route requires navigating through the rugged terrain of the Arabian Peninsula. Consequently, the direct maritime distance is less than the overland distance, making the sea route the more efficient option.
The channel in a marina would be the entry/egress route to/from the sea or river.
Yes, the River Don connects the Black Sea and the Caspian Sea. It flows into the Sea of Azov, which is linked to the Black Sea, and further extends through the Don River basin. However, there is no direct navigable route between the two seas, as the river system is not continuous due to various geographical features.
A river is not bigger than a sea. A sea is a large body of salt water. A river is a running canal of water (usually fresh water) from precipitation from higher elevations of land (such as mountains).
The shortest trade route between India and Constantinople would be the land and sea route. This route would involve traveling overland from India to a port on the Arabian Sea, then sailing across the Arabian Sea, through the Red Sea, and finally into the Mediterranean Sea to reach Constantinople. This combination of land and sea travel would be more efficient than either the land or sea route alone due to geographical constraints and historical trade patterns.
The Nile and Yangtze combined brings more water than any other river into the sea. Plus the rivers run into the Mediterranean Sea.
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.
The sea route was often better than the land route for several reasons: first, it allowed for the transportation of larger quantities of goods over longer distances without the constraints of terrain. Second, maritime travel typically faced fewer obstacles, such as natural barriers and hostile territories, making it safer and more efficient. Finally, sea routes were generally faster, as ships could maintain steady speeds over water compared to the slower, more variable pace of land travel.
The Volga River flows through central Russia, starting in the Valdai Hills and ending at the Caspian Sea. It is the longest river in Europe and an important transportation route and water source for many cities along its banks.
