A flow in an open channel is said to be uniform if its properties remain constant with respect to space. Detailed discussion about Uniform Flow.
Open channel flow refers to the flow of liquid in channel open to atmosphere or in partially filled conduit (Pipe). Example- River, Flood, Rivulets, Torrent, Sewers carrying sewage, Rode side Gutter. Detailed discuss about OCF.

Traffic studies or surveys are carried out to analyze the traffic characteristics. These studies help in deciding the geometric design feature and traffic control for safe and efficient traffic movements. The traffic surveys for collecting traffic data are also called traffic census. The various traffic studies generally carried out are: Traffic Volume Study, Traffic Speed Studies.
The basic objective of traffic engineering is to achieve free & rapid flow of traffic with least no of accidents. For this various studies are carried out. These studies are divided into- Traffic Characteristics, Traffic Studies and Analysis, Traffic Control Regulation.

Vertical Curve are provided at the intersections of different grades to smoothen the vertical profile. The vertical curve used in the highway are of two types: Summit Curve, Valley Curve.
A theodolite is an important instrument used for measuring horizontal and vertical angles in surveying. The system of surveying in which the angles (both horizontal & vertical) are measured with the help of a theodolite, is called Theodolite surveying.
In special instrument, we detailed discuss about hand leveling, abney level, indian pattern clinometer, ceylon ghat tracer, sextant, site square, mining dial, brunton’s compass, pantagraph, eidograph.
