Fortunately for life, as we know it, on Earth, water has the amazing property of cohesion which allows it to be a liquid.
As the water flows over the rim, it's all cohesively connected and uniform, then gravity causes it to increase speed. When the water accelerates it gets torn away from the slower water behind and the faster water ahead. Droplets form of the water that's close enough in speed to have cohesion triumph. That's the white in the first picture, water droplets which scatter light.
