DIQUE / ESPIGAO, COLUMNAL BASALTIC LANDSCAPE

摘要

A mosaic seawall comprises a fascine of vertically-elongated structural prisms of generally identical cross-section. Each of the elements has at least one lateral face abutting a lateral face of another of the prisms to define a common lateral face extending substantially the full vertical extent of at least one of the abutting prisms. A plurality of the prisms together define in cross-section a stable mosaic to resist overturning or sliding under the wave action, a plurality of the prisms together defining an echeloned or vertically stepped mosaic crest.
