Abstract

Un « creux marin (UTSURO) » est une partie d'une zone recouverte d'eau entourée et enfermée par une structure de banc dans une zone marine changeant suivant le niveau de la marée. En utilisant un générateur de marée près d'un « creux marin (UTSURO) » qui étale une embouchure de canal qui ouvre une zone d'eau de « creux marin (UTSURO) » par l'intermédiaire d'un canal en direction d'une partie amont de rivière pour l'ouvrir dans une zone d'eau en amont de rivière et changeant avec le niveau de marée, l'extension fonctionnelle d'une rivière est réduite, un gradient du lit de rivière est accentué, le débit et la force de traction d'une rivière sont accrus, un lit de rivière est creusé, une zone de section de rivière est agrandie, et l'écoulement des eaux d'un bassin interne ainsi que la capacité d'évacuation du flux sont accrus. Au niveau d'une partie en aval, la taille du « creux marin (UTSURO) » A est accrue, une capacité de production d'un courant de marée est renforcée, un courant de marée aussi important en intensité qu'une inondation est produit, une surface de section de courant d'eau est agrandie, ceci permettant d'obtenir un effet de lutte contre les inondations et d'entretien des voies d'eau. En outre, afin de retirer des quantités énormes de sable et de terre entraînées dans le flux vers une embouchure de rivière et déposées sur un lit de rivière, un autre « creux marin (UTSURO) » B riche en trous est installé pour capturer les boues par l'action de la marée haute aux fins de la précipitation et du nettoyage permettant le développement d'étendues plates intertidales et de terres gagnées sur la mer, et, à marée basse, le surnageant propre est recueilli dans un canal afin de produire la marée. En outre, l'installation d'un banc enfermant des bancs externes (8) peut empêcher un débit sortant de boue dans une zone marine externe et renforcer les effets d'entretien d'un canal. De plus, afin de conserver les fonctions du « creux marin (UTSURO) » A, la longueur de canal est accrue pour empêcher une entrée d'eau trouble.
