Long Profiles Water On The Land The water cycle. this is a series of processes by which water is evaporated from the sea and eventually condenses and precipitates over the land. it is the main input to the drainage basin and you can read detailed notes on this process at the met office's website. changes in river variables characteristics long profiles. The long profile shows the gradient of a river as it journeys from source to mouth. it spans the source of a river (where it starts) and the mouth (where it reaches the sea). the long profile of a river is a way of displaying the channel slope (gradient) of a river along its entire length. therefore, it shows how a river loses height with.
Long Profiles Water On The Land The yangtze river. the yangtze is the longest river in asia, with a length of over 6,300 kilometres. its long profile has a steep gradient in the upper course, where the river flows through a series of deep gorges and rapids. in the middle and lower course, the river flows through a wide floodplain and delta, where it is home to a variety of. A long profile close long profile a section when the land is eroded or worn away in a downwards direction, eg a river that is high up will erode vertically because gravity pulls the water. River cross profiles show you a cross section of a river’s channel and valley at certain points in the river’s course. the cross profile of a river changes as it moves from the upper to lower course as a result of changes in the river’s energy and the processes that the river carries out. in the upper course, the valley and channel are. Long profile of a river the steep reduction in height near the source gives way to a more gradual reduction further downstream, giving a typical concave profile. the river has much potential energy near the source due to the steep drop. later on, this is replaced by energy from a large volume of water. however, such a perfect long profile is rare.

The long profile. the long profile of a river marks its change in gradient and altitude from its source to its mouth. it shows how a river changes throughout its course. long profiles are concave in shape and depict how a river’s slope becomes gentler as it nears the sea. the long profile also illustrates how from its source, the river’s. Then plot a graph with the riverbed elevation on the vertical axis and the upstream distance on the horizontal axis. pass a smooth curve through the points. the result is what is called the longitudinal profile (or long profile) of the river. the longitudinal profiles of most rivers are concave upward, as shown in figure 5 19.
