in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.

sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

Discharge is the volumetric rate of water flow past a point at a particular time.

Discharge = $\frac{volume of water}{time}$

We see that discharge is directly proportional to the volume of water in a stream.
It is inversely proportional to the time taken.
We know that volume is the amount of space occupied by a body. It is function of its size and shape.
A big water body that is deeper, wider and longer will have more wate and a greater discharge.
