Basically, tidal wave is the rising of the earth ocean's surface caused by the relative motion of the Earth, Sun and the Moon, which interact via gravitational forces. It arises because the gravitational force exerted on one body by a second body is not constant across its diameter. The side nearest to the second body experiences a greater force, while the opposite side experiences a lesser force. However, tidal wave can also be created artificially using engineering approaches. It can be generated by consistently moving water with a moving pallet, swinging gate, or movable immersed block. This eventually will create disturbance at the water surface and lead to the creation of tidal wave. This project is about designing and modeling a scaled-down model of a tidal wave generating system. A water container, installed with four pressure chamber was designed and fabricated to store water. Vertical pressure is applied inside those chambers using pedals driven by DC motors. The pedals are installed inside the chambers at the water container which are controlled by PLC. The PLC is a control system which takes and processes input from the control panel and send the output to the external relay system. The outputs sent by the PLC to the external relay system will determine forward and reverse movement of the DC motors. By then, artificial tidal wave is created in the water container. The waves formed can be used for structural test and learning tools. Apart from that, the concept can also be applied at water theme parks during the process of making artificial tidal waves.
