Tombolo near Karystos, Euboea, Greece Tombolo contrasted with other coastal landforms.. A tombolo is a sandy or shingle isthmus.A tombolo, from the Italian tombolo, meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ayre (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a ...
A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
The sandy isthmus or tombolo "The Neck" connects North and South Bruny Island in Tasmania, Australia. An isthmus (/ ˈ ɪ s m ə s, ˈ ɪ s θ m ə s /; [1] pl.: isthmuses or isthmi) [2] is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated.

Los Morrillos de los Cabos Rojos (Spanish for "the little promontories of the red capes") or more commonly known as Los Morrillos de Cabo Rojo, is a cape and tombolo landform located in southwestern Puerto Rico in the municipality of Cabo Rojo. Los Morrillos is an excellent example of a tombolo, or a tied island, with two sand pits.
An additional rubble mound is sometimes placed in front of the vertical structure in order to absorb wave energy and thus reduce wave reflection and horizontal wave pressure on the vertical wall. Such a design provides additional protection on the sea side and a quay wall on the inner side of the breakwater, but it can enhance wave overtopping .
In telecommunications and transmission line theory, the reflection coefficient is the ratio of the complex amplitude of the reflected wave to that of the incident wave. The voltage and current at any point along a transmission line can always be resolved into forward and reflected traveling waves given a specified reference impedance Z 0.
A typical example of glide reflection in everyday life would be the track of footprints left in the sand by a person walking on a beach. Frieze group nr. 6 (glide-reflections, translations and rotations) is generated by a glide reflection and a rotation about a point on the line of reflection. It is isomorphic to a semi-direct product of Z and C 2.
An example of this type of cuspate foreland is the one found at Dungeness along the southern coast of Britain. [6] This cuspate foreland has formed as a result of the merging of SW waves from the English Channel, and waves from the east from the Strait of Dover. [ 4 ]
