Respuesta :
The velocity of a stream is tied to the discharge of a stream then the average velocity of a stream is constant.
The percentage increases when water is added to the river via tributaries. This means that less water is in contact with the bed and estuary so less energy is expended to overcome friction. As a result the river flows progressively faster downstream. The higher the slope the faster the current will flow. Channel shape and texture.
The shape and roughness of the channel also affect the speed of the water flow. This is because as rivers move downstream they tend to get deeper and wider discharging greater volumes. As a result, relatively less water comes into contact with the wet surroundings reducing river water friction from downstream channel floors and banks and resulting in a faster flow.
