Can someone me with this question

In this question, effect of three parameters (water volume, incline gradient, and temeprature) is inquired towards stream energy. Here I have discussed all of them in detail:

Water volume: volume of water is directly proportional to the energy of stream. More water increases the volume of the stream and speeds up the flow.

Inclined gradient: Inclined gradient will increase the effect of gravity and thus speed of water. The water at higher elevation will have more potential energy, which upon moving downhill, will be converted to kinetic energy and increase the stream energy.

Temperature:  Temperature is also positively correlated with the energy of stream. The increased water temperature will cause water molecules move faster. Hence, the stream energy will also be increased.
