A fixed Data Capsule of VDR mounted on a container ship. Voyage data recorder, or VDR, is a data recording system designed for all vessels required to comply with the IMO 's International Convention SOLAS Requirements (IMO Res.A.861 (20)) in order to collect data from various sensors on board the vessel. It then digitizes, compresses and stores ...
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 ...
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 runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess. [1] The curve number method was developed by the USDA Natural Resources Conservation Service, which was formerly called the Soil Conservation Service or SCS — the ...
If the bay number is odd it is suitable for 20 feet containers, if the bay number is even it is suitable for 40 feet containers. [3] [12] Container slot, position or cell – names of the spaces that containers can be loaded in. On a stowage plan their positions are identified by a six-digit coordinate number: Bay-Bay-Row-Row-Tier-Tier. [3] [5 ...
The International Association of Classification Societies (IACS) is a technically based non-governmental organization that currently consists of twelve member marine classification societies. More than 90% of the world's cargo-carrying ships’ tonnage is covered by the classification standards set by member societies of IACS. [1]
A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt's drainage equation. A well known steady-state drainage equation is the Hooghoudt drain spacing equation.
A nautical chart or hydrographic chart is a graphic representation of a sea region or water body and adjacent coasts or banks. Depending on the scale of the chart, it may show depths of water (bathymetry) and heights of land (topography), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and ...
