Why water seems to be white when it is faster and why it looks transparent when it is slow moving? and why it seems to be blue when it is in its normal speed?

Water never appears blue in normal conditions. It merely partially reflects the sky above. It is transparent by its color and it appears white when flowing in speed due to the formation of bubbles of air (froth).
