Webb10 jan. 2024 · The basin was 55 m long, 34 m wide, and 0.7 m deep. At one end of the basin was the piston-type wave maker consisting of 70 paddles. The concrete plane beach model was rotated at an angle of 30° to the wave maker and had a longshore dimension of 29 m. The shortest distance from the toe of the beach to the wave maker was 8 m. WebbThe project of a wave maker requires a mathematical formulation for the water waves propagation. Linear and non linear theory for water waves are presented in Le Méhauté (1976), Dean and Dalrymple (1991), Rahman (1995), Chakrabarti (1994) and Battacharyya, (1978). The mathematical connection between desired waves and wave maker is
