A good example of an original basement science research project is setting up an apparatus to create and study the interference of two hydraulic jumps on an inclined surface. There was a study done by a student at his house for two interfering hydraulic jumps on a flat surface some years ago at Evanston, but now a student was interested in taking that type of study and tilt the surface through a range of angles. Preliminary results are in a paper the student wrote.
There is an extension that can be done on this experiment. One possibility is to try even larger angles, as well as vary the flow rates of one or both of the jets. For any of these studies, one could also take the best-fit functions of these data and modify existing theoretical equations for jump radii - an empirical formula at the very least could be developed to explain this phenomenon.
