Average velocity increases downstream because of the overall flow of the river. As the river moves in the downstream direction, the volume of water increases due to tributaries adding water along the way. This increase in water volume results in a higher average velocity as the same amount of water needs to flow through a larger channel.
As energy from waves moves through the water, the water itself also moves in a circular motion. This circular motion involves the transfer of energy through the water column, causing a vertical and horizontal movement of water particles in the direction of the wave propagation.
The heat transfer in this scenario is primarily through conduction, where heat is transferred from the pot to the water through direct contact. As the water at the bottom of the pot absorbs heat, it becomes less dense and starts to rise, leading to a process of convection where the warmer water moves upward and the cooler water moves downward.
The energy for rivers primarily comes from gravity. Water flows downhill due to gravity, creating the kinetic energy that moves the water downstream. Additionally, sunlight provides energy for the water cycle which drives the movement of water in rivers.
If the boat is moving downstream, you add the speed of the boat with the speed of the river flow. Therefore, the velocity of the boat downstream is 18 km/h. If the boat is moving upstream, you subtract the river flow speed from the boat's speed, so in this case, it would be 12 km/h.
To regulate itself so it can continue flowing.
the currents push it downstream
The gradient of a stream affects the speed of the water as it moves downstream. The steeper the gradient, the faster the water moves.
That means that the water either flows downstream, or falls down, depending on the case.

it decreses
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
As energy from waves moves through the water, the water itself also moves in a circular motion. This circular motion involves the transfer of energy through the water column, causing a vertical and horizontal movement of water particles in the direction of the wave propagation.
Water flows from a higher elevation to a lower elevation due to gravity. It seeks the lowest point possible as it moves downstream.
Water in a wave moves in a circular motion, with the water particles moving in an orbital path and not moving very far forward as the wave passes through. This movement is a transfer of energy rather than a transfer of water mass.
Valley's or hills. Wind and water erosion moves light particles from river banks and shores making new landmasses both downstream and at the sight of erosion.
