To restrain oscillation associated with motion of water accumulated in a floating body type artificial tidal flat from being magnified when the floating body type artificial tidal flat oscillates due to impact of waves.SOLUTION: A floating body type artificial tidal flat which is floated on a water surface comprises a bottom plate part 21 and longitudinal wall parts 22, 23 which are vertically arranged around circumference of the bottom plate part 21 in a fence-like shape and includes a floating body structure 20 which is composed so as to float on the water surface and a base bottom part 30 which covers the bottom plate part 21 at inside of the longitudinal wall parts 22, 23 of the floating body structure 20 and composes a tidal flat by one part being submerged under water accumulated within the floating body structure 20. A base bottom surface 32f which is capable of directly contacting with water in the base bottom part 30 is configured so that height size becomes smaller continuously as approaching from one end side to a central part in a direction along a proceeding direction W of waves around the floating body structure 20 and height size becomes larger continuously as approaching from the central part to other end side.SELECTED DRAWING: Figure 3 【課題】波の影響で浮体式人工干潟が揺動する際、その浮体式人工干潟に溜められた水の移動に伴う揺動の増幅を抑制する。【解決手段】水面に浮かべられる浮体式人工干潟であって、底板部２１と、底板部２１の周縁に塀状に立設された縦壁部２２，２３とを備え、水面に浮かぶように構成された浮体構造物２０と、浮体構造物２０の縦壁部２２，２３の内側で底板部２１を覆っており、一部が浮体構造物２０内に溜められた水に水没することで干潟を構成する基底部３０とを有しており、基底部３０において水が直接的に接触可能な基底表面３２ｆは、浮体構造物２０の周囲の波の進行方向Ｗに沿う方向における一端側から中央部に近づくにつれて高さ寸法が連続的に小さくなり、前記中央部から他端側に近づくにつれて高さ寸法が連続的に大きくなる。【選択図】図３
