  2. Open channel spillway - Wikipedia

    en.wikipedia.org/wiki/Open_channel_spillway

    Q mi = discharge capacity without freeboard (ft 3 /s) (In this case, freeboard is the vertical distance from the water surface to the dam crest when the water surface is at a lower elevation.) L = length of the spillway crest (ft) H = height of the sidewalls above the spillway crest (ft)

  3. Freeboard (nautical) - Wikipedia

    en.wikipedia.org/wiki/Freeboard_(nautical)

    In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion measured relative to the ship's load line , regardless of deck arrangements, is the mandated and regulated meaning.

    Eq. 2 is the cumulative Weibull distribution with scale parameter and shape parameter ; = [^ ()] = constant factor depending on the structure geometry, = structure volume; = relative (size-independent) coordinate vectors, ^ = dimensionless stress field (dependent on geometry), scaled so that the maximum stress be 1; = number of spatial ...

  5. Superstructure - Wikipedia

    en.wikipedia.org/wiki/Superstructure

    The height and the weight of superstructure on board a ship or a boat also affects the amount of freeboard that such a vessel requires along its sides, down to her waterline. In broad terms, the more and heavier superstructure that a ship possesses (as a fraction of her length), the less the freeboard that is needed.

    en.wikipedia.org/wiki/Ship_measurements

    Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessels displacement (obtained from ships stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is loaded ...

  9. Air draft - Wikipedia

    en.wikipedia.org/wiki/Air_draft

    The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the underside of the bridge at the chart datum Mean High Water (MHW), [3] [4] a less restrictive clearance than Mean Higher High Water ...
