System and method for generating reverse-flow tsunami waves under laboratory conditions

A method for generating reverse-flow tsunami waves under laboratory conditions comprising the steps of:

• providing a system comprising:
• an elongated simulation channel having a first side region, a second side region in a position opposite to the first side region and a measurement region positioned between the first side region and the second side region;
• a first basal gate configured to selectively control a first fluid outlet from the elongated channel by opening and closing it and a first emerging gate positioned in the first side region;
• a second basal gate configured to selectively control a second fluid outlet from the elongated channel by opening and closing it and a second emerging gate positioned in the second side region, at least one fluid driving pump, flow measuring and control means, a fluid circulation line comprising a main fluid line, a first fluid inlet line in the first side region and a second fluid inlet line in the second side region;
• and a control system of the at least one driving pump, of the first basal gate, of the second basal gate of the first emerging gate, of the second emerging gate, and of the measuring means, wherein the measuring means comprise a first fluid level sensor positioned in the first side region, a second fluid level sensor positioned in the second side region, and a third fluid level sensor positioned in the flow measuring and control region;
• performing a first experiment of generating a tsunami wave in a first direction by means of a flow driven by the at least one fluid driving pump through the main line, and the first fluid inlet line, and by controlling the fluid level by means of the second emerging gate the second basal gate and the control system;
• and
• performing a second experiment of generating a tsunami wave in a second direction by means of a flow driven by the at least one fluid driving pump through the main flow line, and the second fluid inlet line, and by controlling the fluid level by means of the first emerging gate, the first basal gate, and the control system.
