Prediction models can identify eroded waterways from digital terrain information, and thereby identify placement of grassed waterways to reduce soil erosion.Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion channels will likely form could help farmers and conservation professionals do a better job of designing and locating grassed waterways in...

A straight line may be the shortest distance between two points, but it isn't necessarily the fastest or easiest path to follow.That's particularly true when terrain is not level, and now American and British researchers have developed a mathematical model showing that a zigzag course provides the most efficient way for humans to go up or down steep slopes."I think zigzagging is something people do intuitively," said Marcos Llobera, a University of Washington assistant professor of...

Word of the Day
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
