H s is the design significant wave height at the toe of the structure (m) Δ is the dimensionless relative buoyant density of rock, i.e. (ρ r / ρ w - 1) = around 1.58 for granite in sea water; ρ r and ρ w are the densities of rock and (sea)water (kg/m 3) D n50 is the nominal median diameter of armor blocks = (W 50 /ρ r) 1/3 (m)
Rubble masonry or rubble stone is rough, uneven building stone not laid in regular courses. [ 1 ] [ 2 ] It may fill the core of a wall which is faced with unit masonry such as brick or ashlar . Some medieval cathedral walls have outer shells of ashlar with an inner backfill of mortarless rubble and dirt.
the wall is made of rubble stone with a high proportion of mortar; it has a curved ground plan; it has facing brickwork (Vorsatzmauerwerk or Verblendung) on the upper part of the upstream side; it has an earth embankment against the lower part of the upstream side, the so-called Intze Wedge (Intze-Keil) [2]
Core-and-veneer, brick and rubble, wall and rubble, ashlar and rubble, and emplekton all refer to a building technique where two parallel walls are constructed and the core between them is filled with rubble or other infill, creating one thick wall. [1] Originally, and in later poorly constructed walls, the rubble was not consolidated.
For design purposes, for the coefficient c p the value of 5,2 and for c s the value 0,87 is recommended. [2] Notional permeability according to Van der Meer (1988) The value of P can be read from attached graph. Until now, there is no good method for determining P different than with accompanying pictures.
Rubble-work on Wyggeston's Chantry House in Leicester, built c. 1511 "Rubble-work" is a name applied to several types of masonry. [1] One kind, where the stones are loosely thrown together in a wall between boards and grouted with mortar almost like concrete, is called in Italian "muraglia di getto" and in French "bocage". [1]

Riprap (in North American English), also known as rip rap, rip-rap, shot rock, rock armour (in British English) or rubble, is human-placed rock or other material used to protect shoreline structures against scour and water, wave, or ice erosion.
