When photographing moving water, look for the direction of the flow and any shapes that might be created by that flow. You might have to stand and watch for awhile, and slow your mind down in order to see shapes that might be there. You can learn this technique easily if you are patient and concentrate.
Look for gaps between rocks where the water is channeled and generally flows faster because of the narrow channel. It is in those areas where finding shapes is easier. You will see the water funnel in, creating a triangular shape as in this image.
Also look for colors reflected in the water. Again, take your time and be patient. You might have to take a shot or two and look at the image on the back of your camera in order to see hints of color. After a little practice you will be able see the colors with your unaided eye.
When training yourself, you do not have to be at the most spectacular stream or the fastest moving water. Find any nearby stream or river, and then sit and watch. Be patient with the water and be patient with yourself. It may take several visits and many shots before your eye begins to see which areas of the water are best to shoot. Shoot a lot of images from different angles and different vantage points.
Over time you will notice that your success rate has improved, and that finding interesting sections of water to shoot has gotten easier.
