Answer:
They have reduced the river's force to almost nothing by the time it finally empties into the sea.
Explanation:
The Colorado River is one of the biggest rivers in North America. It runs mostly through the United States and little through Mexico where it ends its flow and empties into the sea. This river has been the subject of heavy exploitation by humans, and for that purpose, numerous dams have been built on it.
The number of dams is so high and the water is used at such a high rate that the river barely has any water as it empties into the sea. As this river runs mostly through arid and semi-arid areas that are also used for agriculture, its waters are heavily used for irrigation, leaving less and less water in the river as it gets closer to its endpoint. The dams are helping a lot in the economies of the states through which the Colorado River runs but the effect on the ecosystem of the river has been devastating.
The greatest common factor is 1

Answer:
Stream gradient refers to the slope of the stream's channel .It is the vertical drop of the stream over a horizontal distance.
Explanation:
Gradient is the slope or steepness of a stream channel. It affects the stream's velocity because the steeper the gradient is the greater the velocity due to gravity.
