Hence, something like hydraulic jump continuously provides new, original research options. For example, one option is to have multiple streams of water forming multiple jumps, that can interfere with each other. Another option is to study jumps on inclined surfaces. But what about combining those studies into one? This is an option a student recently has done, as a preliminary project. Check out the video for some pointers about how ANYONE can do this at a school or at home, and how there are so many more questions that can come from this preliminary one: from the fits of these data, can someone take existing theoretical math models for single jumps and modify it, at least as an empirical formula, to make a math model for interfering jumps? For jumps on an angle, where a component of gravity enters the model? And then for the combination of the two? What about interference patterns one can see in the video for this project? All of those flow details are not yet studied and documented! Numerous more projects can be developed just from this one study. Be creative, explore, ask questions, and the build an experiment to look into your questions - this is science research at its finest!

Two hydraulic jumps on an incline
One way professors run their research programs, and as they go from year to year and have new graduate students joining their team while older ones graduate and leave the team, is to have extension on earlier projects and studies. Good research projects are those that have interesting questions studied, but when answers are found there are even more new questions developed because of the study.

Initial study of interfering dual hydraulic jumps on incline
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.
