One physical factor that can increase a river's discharge is heavy rainfall, which leads to more water flowing into the river. This can cause the river to overflow its banks and increase its discharge. Another factor is snowmelt, where melting snow adds more water to the river, increasing its flow. Lastly, changes in the topography or geology of the river basin can alter the river's discharge by affecting how quickly water is able to flow into the river.
High precipitation intensity can lead to increased runoff into a river channel, causing a higher discharge. This can result in flooding and erosion due to the higher volume of water flowing through the channel. Conversely, low precipitation intensity can lead to lower discharge in the river channel, potentially causing water shortages and impacting ecosystems that rely on the river for water.
Factors that can cause a river's speed and discharge to decrease include reduced precipitation leading to lower water input, increased evaporation, and human activities such as damming that restrict flow. Additionally, changes in land use like deforestation can decrease runoff and thus reduce the speed and discharge of a river.
A river discharge is usually greatest at a given fall.
river discharge is when the amount of water is measured and the amount that is in the river channel, and at a given point (width,length,depth)
The Amazon River.
The physical characteristics of a river vary according to age. In a young river, one would expect to find a steep gradient (slope), high discharge, rapids, steep sides, no floodplain, and a lot of downcutting. In a mature river, one would expect to find a medium gradient, meadows, some meanders (bends in the river path), a narrow floodplain, lateral erosion, and medium discharge. In an old river, one would expect to find large meanders, a wide floodplain, more lateral erosion, and low discharge.
The River Thames discharges into the North Sea.
lots of deposition low velocity (speed) deposition slows it down. low discharge (amount of water) shallow and narrow high energy above sea level
The discharge of a river is the discharge that the river puts out into the sea. This is often the finer silt that the river has picked up and carried from the upper and lower reaches of the river.
The virtual river discharge answers will not be able to be obtained via the internet. The material will have to be reviewed to obtain the answers.
