River training structures will help to modify the hydraulic flow and the sediment response of a river. [5] Miyagase Dam in Japan. Humans have modified the natural behavior of rivers for longer than history is recorded. The management of water resources, protection against floods and hydropower are not new concepts. Regardless, river engineering ...
[7] The sediment yield of a river is the quantity of sand per unit area within a watershed that is removed over a period of time. [11] The monitoring of the sediment yield of a river is important for ecologists to understand the health of its ecosystems, the rate of erosion of the river's environment, and the effects of human activity.

Rivers get their alluvium from erosion, which carves rock into canyons and valleys. Rivers have sustained human and animal life for millennia, including the first human civilizations. The organisms that live around or in a river such as fish, aquatic plants, and insects have different roles, including processing organic matter and predation.
A river valley civilization is an agricultural nation or civilization situated beside and drawing sustenance from a river. A river gives the inhabitants a reliable source of water for drinking and agriculture. Some other possible benefits for the inhabitants are fishing, fertile soil due to annual flooding, and ease of transportation.
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
The Peninsular Rivers are mostly fed by the rainfall. During the summer, their discharge is significantly less. Some of their confluents indeed get dehydrated, purely to be regenerated in the monsoon. The catchment region of the Godavari River in the peninsula is the biggest in India, covering a territory of around 10% of the whole country.
A stone near Crissolo, Italy, is inscribed, "Here is born the Po".. The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream".
The Deccan rivers system consists of rivers in Peninsular India, that drain into the Bay of Bengal and the Arabian Sea. There are numerous short coastal rivers, predominantly on the West coast. There are few inland rivers, which do not drain into sea. [2] [3] Most of the rivers in India originate from the four major watersheds in India.
