Load line (watercraft) The load line, also known as Plimsoll line, indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, [1] particularly with regard to the hazard of waves that may arise. The load line is a waterline that corresponds to the maximum draft of the ...
Atterberg limits. The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different ...
The International Convention on Load Lines (CLL), was signed in London on 5 April 1966, amended by the 1988 Protocol and further revised in 2003. The convention pertains specifically to a ship's load line, a marking of the highest point on a ship's hull that can safely meet the surface of the water; a ship that is loaded to the point where its load line is underwater and no longer visible has ...
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the ...
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients.
The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes. The classification system was first developed by Hogentogler and Terzaghi in 1929, [1] but has been ...
Matthew Vaughan, chief scientist for the Lake Champlain Basin Program, spoke on the State of the Lake briefly, but refocused to talk about how flooding in the lake's basin affects the water quality.
The Runnymede-class large landing craft are powered watercraft in the United States Army. They replaced older USN-design landing craft, and are a typical Landing Craft Utility design with a bow ramp and large aft superstructure. They transport rolling and tracked vehicles, containers, and outsized and general cargo from ships offshore to shore ...
