The periodic water tank structure and topological transition for water waves.

(a) the three dimensional view of one unit cell of water tank with lattice constant 2a. (b) the topological transition point at Δw = 0. Parameters: lattice constant 2a = 0.4 m, radius of cylinder tank r = 0.4a, water depth h = 0.5a (intermediate water waves), width of connecting rank w = 0.16a.
