   Jul 30, 2018 · The slope of a river decreases as it flows progressively downstream. Gravitational force is stronger uphill, but gentle in the lower course. The water tends to flow slowly due to higher water friction, hence the width increases. Towards the mouth, the gradient is lower, enabling water to flow on a wide surface area.

   Mar 22, 2021 · River processes. River features. Slip-off slope. Oxbow lakes. In the middle course of a river the gradient decreases (it flattens out) and the discharge increases. This is due to the fact that many more tributaries have joined the main channel, leading to an increased volume of water, as well as the fact that the high level of gravitational ...

   Why does the width of a river increase?

   • The larger mass of water causes wider and deeper water channels in order to allow water in the river to flow more freely. The slope of a river decreases as it flows progressively downstream. Gravitational force is stronger uphill, but gentle in the lower course. The water tends to flow slowly due to higher water friction, hence the width increases.

   Why does river water flow slowly?

   • The water tends to flow slowly due to higher water friction, hence the width increases. Towards the mouth, the gradient is lower, enabling water to flow on a wide surface area. River water carries millions of tonnes of sediments. The sediments are both suspended load and bed loads.

   What factors contribute to the widening of a river downstream?

   • In the middle phase, the river morphology changes in width and depth. As the river gathers momentum downstream towards the lower course phase, the width reaches its widest point. The following factors contribute to the widening of a river downstream. The volume of water increases downstream due to increasing inlets from tributaries and rainwater.

   How does a river affect the flow of water?

   • Additionally, less water is in contact with the river bed, which results in less energy needed overcome friction. The larger mass of water causes wider and deeper water channels in order to allow water in the river to flow more freely. The slope of a river decreases as it flows progressively downstream.

   How does the size and shape of a river change as flows downstream?

   • The size and shape of a river changes as flows downstream. The course of a river begins in relatively high areas, with a very narrow width depending on the source. However, different processes occur in different stages downstream. There are three distinct stages: the upper, middle, and lower course.

   Why does a river become bigger if it erodes?

   • However, downstream the water flow meanders due to the erosion of outer parts of bends in the river. The river becomes wider as the meandering channel is eroded and washes away more materials along the riverbank. The cross-sectional area of the river, therefore, becomes larger.

Two sets of variations take place: variations at a particular cross section (at-a-station) and variations along the length of the stream (downstream variations). Characteristics responsive to analysis by hydraulic geometry include width (water-surface ...
