A term used to describe the movement of a particle being transported by wind or water which is too heavy to remain in suspension The particle is rolled forward by the current, generates lift and rises, loses the forward momentum supplying the lift and settles to the floor, where the process is repeated The size of the particles which can be saltated depends upon the velocity of the current and its density, e g , water will saltate larger particles than air at the same velocity
A particular type of momentum-dependent transport involving: (i) The rolling, bouncing or jumping action of soil particles 0 1 to 0 5 mm in diameter by wind, usually at a height
A condition which exists in a moving stream of slurry when solids settle in the bottom of the stream in random agglomerations which build up and wash away with irregular frequency
movement of individual particles as variable leaps or jumps powered by wind or water; a "roll-and-bounce" motion
a mutation that drastically changes the phenotype of an organism or species (geology) the leaping movement of sand or soil particles as they are transported in a fluid medium over an uneven surface
(geology) the leaping movement of sand or soil particles as they are transported in a fluid medium over an uneven surface
An abrupt and marked variation in the condition or appearance of a species; a sudden modification which may give rise to new races
Transport of sediment initiated by moving air or water where particles move from a resting surface to the transport medium in quick continuous repeated cycles
