Design and Manufacturing of Small Scale Tsunami Simulator Channel

Abstract

Increasing the cost of in-situ or field tests to solve engineering problems, particularly water engineering, pushes researchers worldwide to simulate different water engineering problems using small-scale physical modeling like soil erosion, hydraulic jump, water flow, and underground water. This paper focuses on the design, manufacturing, and calibration of the 6 m small-scale tsunami simulator channel to investigate the tsunami wave behavior with time until it reaches the shore or beach. The new wave generator capable of recreating scaled tidal waves, the physical modeling of tsunamis in the laboratory, and has advanced significantly. The working principles behind the new wave generator and its design, manufacturing, and first stages of testing to validate its capacities and limitations are discussed in this paper. Each part of the generator has been represented; model preparation and new wave generator calibration have been discussed. Well, agreement of the wave height is noticed (14 cm), and this is replicated that the new wave simulator can reproduce solitary waves with high steepness.
