Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional position of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish land maps and boundaries for ownership, locations like building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales.

“The way we treat stormwater, especially in California, is broken,” explains Joseph Charbonnet, a graduate student in civil and environmental engineering at UC Berkeley. “We think of it as a pollutant, but we should be thinking about it as a solution.” 

As water flows through urban areas, over rooftops, lawns, and

Exploring Subsurface Detection Technologies and Methods

Many popular sayings are polar opposites of each other. “Look before you leap” is the exact opposite of “He who hesitates is lost.” However, a successful earthwork contractor must do both simultaneously. They must avoid the hidden dangers that can lurk below ground at any job site. They must also

Use and Chemical Composition of Turbine Lubricants

Lubricants are materials that reduce friction by increasing the smoothness of moving surfaces in contact. All solids have surfaces with imperfections and roughness. These irregularities lead to increased friction and associated heat generation. By covering these imperfections in a viscous material or slippery liquid, friction is reduced and the moving

Groundwater Graphics

It looks like the earth is breathing. The land beneath Southern California appears to rise and fall in two animated graphics created by geophysicists at Caltech. Researchers recently analyzed satellite radar data in order to better understand the effects of groundwater extraction and replenishment on the land. Their findings reveal
