The Geological Cycle of Rock formation

Geological cycle includes many processes acting simultaneously. The most important of these begin with molten magma from within the earth forming into rock, then continue with rocks being broken down into soil, and that soil being converted back into rock.

Freeboard - Types, Determination & Uses

Freeboard is the vertical distance between the crest of the embankment and the reservoir water surface. Free board can be defined in different terms such as: Normal freeboard is defined as the difference in elevation between the crest of the dam and the normal reservoir water level as fixed by design requirements. Minimum freeboard is defined as the difference in

Highway Capacity | Definition, Types & Factors

It is the ability of a road to accommodate traffic volume. It is the maximum hourly rate at which vehicles can reasonably be expected to cross a point on a roadway during a given time period under prevailing traffic roadway and control condition. For multi lane highway it is 2000pcphpl,

Design & Construction of Steel Structures

it is the ability to redistribute the load. Simple beam is determinate. Fixed beam is indeterminate by 2 degrees so it has two redundant actions. fixed supported beam is more better as indeterminate structure can redistribute the load. When load increases support becomes plastic and it turns into a simply supported beam. But simply supported does not go through the stage of plastic

What are Survey Stations and How to Select a Survey Station

Survey Stations is a point of importance at the beginning and end of chain line. There are two types of survey stations: ... These are the end of survey line i.e. which connects boundaries. Line joining Main Stations is called Main Survey Line or Chain Line.

Uses & Design of Flow Equalization Tank

Flow equalization is method used to overcome the operational problems and flow rate variations to improve the performance of downstream processes and to reduce the size & cost of downstream treatment facilities. To prevent flow rate, temperature, and contaminant concentrations from varying widely, flow equalization is often used. Variations occur

Introduction to GeoInformatics

It is a software development and services company providing Geographic Information System (GIS) software and Geo-database management applications. The headquarters of ESRI is in Redlands, California. ESRI uses the name ArcGIS to refer to its suite of GIS software products, which operate on desktop, server, and mobile platforms. ArcGIS includes the following

Definition, Advantages & Disadvantages of Freeways

A freeway or corridor is a long stretch of road connecting various large and small streets intersecting it at various spots. They provide a non stop, comfortable and an easy access to the road users without delays and with less vehicular fuel costs with the presence of grade separated junctions including flyovers and underpasses. Freeways and corridors are free of

Free Flow Speed of a Vehicle

Free-flow-speed of a vehicle is defined as: The desired speed of drivers in low volume conditions and in the absence of traffic control devices. The mean speed of passenger cars that can be maintained in low to moderate flow rates on a uniform freeway segment under prevailing roadway and traffic conditions. Factors affecting free flow speed: Width, Lateral clearance,

Distributary Head Regulator - Definition, Working Mechanism

The distributary head regulator is constructed at the upstream end (i.e., the head) of a channel where it takes off from the main canal or a branch canal or a major dis-tributary. The distributary head regulator should

Culverts Types, Design, Installation and Materials

A culvert is an opening through an embankment for the conveyance of water by mean of pipe or an enclosed channel. OR It is a transverse and totally enclosed drain under a road or railway. Pipe culverts are made of smooth steel, corrugated metal, or concrete material. Their primary purpose is to convey water under roads, although a variety of wildlife use them as

Components of Road Structure

1. Subgrade is the foundation of the road, thus its the lowest and most important component of road structure. 2. SUB BASE Consists of a. Upper Base Courseb. Sub or Lower Base Course... If natural surface is above the formation level then the surface is cut down to proposed sub grade surface If natural surface is below the formation level then the sub grade will be above the

Bending Moment - Definition and Calculation

Bending moment at a point or at a section is the algebraic sum of Moments caused by forces action to the left or right of that point or section. Mathematically it can be written as

Surveying Dictionary Words Starting from B

A back-sight is a reading taken on a position of known coordinate(s). Since a survey progresses from a point of known position to points of unknown position, a back sight is a reading looking "backward" along the line of progress. The first reading of almost any survey job should be a back-sight onto a fixed point of reference, usually a benchmark of some sort.

Surveying Dictionary Words Starting from A

A measure which indicates how closely the coordinates of a point in Ordnance Survey map data agree with the true National Grid coordinates of the same point on the ground. As the true position can never be known exactly, the statistic is quoted relative to the best known position determined by precise survey methods. A coordinate pair or triplate measured directly from
