A branch (of a river) which, after diverging, rejoins the river farther down. The term is used, in particular, for a secondary channel, in a broad plain of braided channels, that maintains a semi permanent course. Examples occur in eastern Australia, the jungles of South America, in the southern Sudan, and elsewhere. See, e.g., billabong.
Industry:Earth science
Side looking radar operating at decimeter wavelengths and measuring the angle at which the radiation is emitted and returned. Most side looking radar operates at millimeter wavelengths. Such radiation is scattered by vegetation and does not reach the ground if the vegetation is dense, and the radar sees only the top of a densely forested region. Radar operating at decimeter wavelengths is able to see through the vegetation to the ground.
Industry:Earth science
The rate of change of velocity with respect to time, measured with respect to axes fixed in space.
Industry:Earth science
Navigation in which the prescribed course is a circular arc and the vessel or aircraft is kept on this course by reference to radio signals from a transmitter at the center of the arc.
Industry:Earth science
