in landscaping, a natural or artificial waterfall descending over terraced steps. In park architecture cascades are created by building at various levels of bodies of water and of steps and terraces over which the water descends. Examples of famous cascades are those in Italy, in the Villa d’Este in Tivoli (1550–72, architect P. Ligorio) and the Villa Aldobrandini in Frascati (1598–1604, architects G. della Porta and C. Maderna), as well as those in the park in Petrodvorets.
In the figurative sense a cascade is a rapid irrepressible flowof something—for example, words or sounds.

A series of actions that take place in the course of data processing, each triggered by the previous action in the series.
An electric-power circuit arrangement in which circuit breakers of reduced interrupting ratings are used in the branches, the circuit breakers being assisted in their protection function by other circuit breakers which operate almost instantaneously. Also known as backup arrangement.
An arrangement of separation devices, such as isotope separators, connected in series so that they multiply the effect of each individual device.
A landform structure formed by gravity collapse, consisting of a bed that buckles into a series of folds as it slides down the flanks of an anticline.
A small waterfall or series of falls descending over rocks.
(cell and molecular biology)
A molecular system that is capable of self-propagation or amplification.
The emission of a series of photons by a quantum system, such as an atomic nucleus or a laser, in an excited state, accompanying transitions of the system to successively lower excited states, until the system reaches the ground state.

cascadeA connected series of devices or images. It often implies that the second and subsequent device takes over after the previous one is used up. For example, cascading tapes in a dual-tape backup system means the second tape is written after the first one is full. In a PC, a second IRQ chip is cascaded to the first, doubling the number of interrupts.
