Dick Newell oversaw the creation of the Plant Design Management System (PDMS) for 3D process plant design. He later co-founded two software companies – Cambridge Interactive Systems (CIS) which was known for its Medusa 2D/3D CAD system, and Smallworld with its eponymous Smallworld GIS (Geographical Information System).
3D view. HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.. The program was developed by the United States Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its ...
A chute spillway is a common and basic design that transfers excess water from behind the dam down a smooth decline into the river below. These are usually designed following an ogee curve . Most often, they are lined on the bottom and sides with concrete to protect the dam and topography.
The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid.Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam ...
Liners generally have a pore structure that is designed to retain the majority of cement and other small fines. This results (for vertical and inclined surfaces) in the creation of a uniform surface relatively free from blowholes and other surface blemishes when compared to impermeable concrete.
It is performed to assess the safe design of a human-made or natural slopes (e.g. embankments, road cuts, open-pit mining, excavations, landfills etc.) and the equilibrium conditions. [1] [2] Slope stability is the resistance of inclined surface to failure by sliding or collapsing. [3]
In software engineering, a pipeline consists of a chain of processing elements (processes, threads, coroutines, functions, etc.), arranged so that the output of each element is the input of the next. The concept is analogous to a physical pipeline .
A cofferdam on the Ohio River near Olmsted, Illinois, built for the purpose of constructing the Olmsted Lock and Dam A cofferdam during the construction of locks at the Montgomery Point Lock and Dam A cofferdam is an enclosure built within a body of water to allow the enclosed area to be pumped out or drained.
