A tsunami wave has been generated like a solitary wave in the laboratory. The dam break model is one method of modeling a tsunami run-up. However, a long flume is required to generate the tsunami run-up and run-down together. This chapter presents the development of methods for generating the tsunami run-up and run-down based on the dam break model using a flume with a limited length. By modifying the release of upstream water using two gates simultaneously, both tsunami run-up and run-down could be generated in a limited-length flume. This method can also be used to generate the run-up and run-down as a single wave to observe scouring around structures caused by a tsunami.
