The vocab word you're looking for is "watershed." A watershed is an area of land where all of the water that falls within it drains into a common outlet, such as a river, lake, or ocean. It often refers to high places, such as mountains or ridges, from which rivers originate and flow down into lower areas.
All rivers start in the high country and end in the Ocean.
It doesn't have to be a high ridge, but in any event, it is the 'Continental Divide'.
In Nepal, perennial rivers are those that flow continuously throughout the year, primarily fed by melting snow and glaciers, as well as rainfall. These rivers originate from the high Himalayan ranges and maintain a consistent flow due to their sustained water sources. Notable examples include the Koshi, Gandaki, and Karnali rivers. Their reliable flow supports agriculture, hydropower, and ecosystems in the regions they traverse.
Indus, Gangas, Brahmaputra.
When Lake Okeechobee's water levels are high, excess water is released into several rivers, primarily the St. Lucie River to the east and the Caloosahatchee River to the west. These rivers facilitate the flow of water from the lake to the Atlantic Ocean and the Gulf of Mexico, respectively. Additionally, water can also flow into the Everglades, contributing to the region's ecosystem.
For the same reason it is salty now. Rivers flow into it but not out and there is a high rate of evaporation.
The area you are referring to is called a watershed or a divide. It is a boundary separating the flow of rivers towards different sides of a continent. The size of the watershed can vary depending on the topography and geography of the region.
The water flow in rivers is too high.Rivers are less productive than swamps because swamps just like marshes have the highest primary production of all the world's ecosystems.
The rivers and streams that flow into the Great Basin are unusual because they are endorheic, meaning they do not flow into an ocean or sea. Instead, they drain into lakes or evaporate, leading to a closed hydrological system. This results in high evaporation rates and high salinity levels in the lakes, as minerals accumulate without being flushed away. The Great Basin's unique geography and climate contribute to this distinctive water behavior.
The Rocky's, idiot
rivers depend on water flow and if they get low waterflow the river wont have enough water
A waterfall is a steep fall or flow of water.
