The Exner equation describes conservation of mass between sediment in the bed of a channel and sediment that is being transported. [1] It states that bed elevation increases (the bed aggrades) proportionally to the amount of sediment that drops out of transport, and conversely decreases (the bed degrades) proportionally to the amount of sediment that becomes entrained by the flow.
Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation (elevators and escalators) around a building. [1]
Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms.Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.
DTED (or Digital Terrain Elevation Data) is a standard of digital datasets which consists of a matrix of terrain elevation values, i.e., a Digital Elevation Model.This standard was originally developed in the 1970s to support aircraft radar simulation and prediction.
Elevation view of the Panthéon, Paris principal façade Floor plans of the Putnam House. A house plan [1] is a set of construction or working drawings (sometimes called blueprints) that define all the construction specifications of a residential house such as the dimensions, materials, layouts, installation methods and techniques.
Classification of Axonometric projection and some 3D projections "Axonometry" means "to measure along the axes". In German literature, axonometry is based on Pohlke's theorem, such that the scope of axonometric projection could encompass every type of parallel projection, including not only orthographic projection (and multiview projection), but also oblique projection.
Even though regular cement mortar can be used, most buildings that use AAC materials use thin bed mortar in thicknesses around 3.2 millimetres (1 ⁄ 8 in), depending on the national building codes. [ citation needed ]
Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. The resulting techniques are important for engineering, architecture, design and in art. [1]
