Imagine you are trying to cross a fast stream that has a constant width. The water is moving at the same velocity along the straight stretch which you must cross. The stream seems to be waist deep and the water is COLD! After scouting, you find a shallow place where it appears that you can wade across with the water only about ankle-deep. So you do it. What happens? (Remember the formula for stream discharge that is given in the text.)
