System for generating progressive water waves in water-filled basin, has displacement element whose geometric shape is designed such that water displacement associated with transition of displacement element is annular

摘要

The system has displacement element (1) which is movable from initial position in which displacement element at rest is partially or entirely above water surface (20) along vertical axis (24) into end position in which displacement element is located partially below water surface such that single progressive water wave is generated by water displacement associated with transition of displacement element. A returning unit makes displacement element to return from end position to initial position. The geometric shape of displacement element is designed such that water displacement is annular. An independent claim is included for method for generating for progressive water waves in water-filled basin.
