A physical phenomenon of free surface swelling found out at the circulating water channel of the National Research Institute of Fisheries Engineering is investigated. Form of measuring section is measured and degree of accuracy is discussed. Fundamental properties of effect to free surface flow due to the friction of boundary layer, bottom and side form of measuring section are examined using open channel theory. Physical reason of the phenomenon of flow surface swelling is explained theoretically. Physical characteristics between profile of free surface and form of measuring section are proposed. As an advanced technology, new form of bottom plane to induce free surface flow included 0-inclination condition under all range of velocity is developed. Actual designing is tried for standard type of circulating water channel under designed velocity of 1 m/s and for high velocity type under 5 m/s.
