When a river originates 200 meters above sea level and travels 400 kilometers to the ocean what is the average gradient in meters per kilometer?

To calculate the average gradient of the river, subtract the elevation at the ocean (0 meters) from the elevation where the river originates (200 meters) and then divide by the distance traveled (400 kilometers). This gives an average gradient of 200 meters / 400 kilometers = 0.5 meters per kilometer. Thus, the average gradient of the river is 0.5 meters per kilometer.


What is the rate of the river's current if a tug tows a barge 24 miles up a river at 10 miles per hour and returns down the river at 12 miles per hour The trip took 5 and a half hours?

Assuming the tug speed is relative to the river flow and is constant over each trip, and the river flows at the same constant rate during the trips, then: Let the flow rate down river be x mph Then the land speed when going upriver is 10 - x mph and the land speed when going down river is 12 + x mph This gives the total time for the journeys: time = distance/speed → 5½ hours = 24 miles/(10 - x)mph + 24 miles/(12 + x)mph → 11/2 = 24(12 + x + 10 - x)/(10 - x)(12 + x) → 11/2 = 24×22/(120 - 2x - x²) → 120 - 2x - x² = 24×22×2/11 → x² + 2x - 120 + 96 = 0 → x² + 2x - 24 = 0 → (x - 4)(x + 6) = 0 → x = 4 or -6 → The river is flowing at 4 mph down the river or 6 mph up the river. If the river is non-tidal, then the river is flowing at 4 mph down the river. (In river terms, up is towards the source of the river, down is towards the mouth of the river, and for a tidal river, eg the Thames between Richmond and its mouth, the current can be flowing up or down the river - the rate will not be constant, but for a period of time whilst the tide is flowing in one direction can be considered to be constant.)


3 Is The Seine bigger than The Thames?

Yes, the Seine is generally larger than the Thames in terms of length and discharge. The Seine, which flows through Paris, is approximately 777 kilometers (483 miles) long, while the Thames is about 346 kilometers (215 miles) long. Additionally, the Seine has a larger average flow, making it a more significant river in terms of water volume.

Mouth Part of a river?

The mouth part of a river is called a delta. It is the large silty area at the mouth of a river at which the river spills into different slow flowing channels.
