Global warming, melting polar caps, rising sea levels and
intensifying wave-current action, factors responsible for the
alarming phenomena of coastal erosion on the one hand and adverse
environmental impacts and the high cost of 'hard' protection
schemes, on the other, have created interest in the detailed
examination of the potential and range of applicability of the
emerging and promising category of 'soft' shore protection methods.
'Soft' methods such as beach nourishment, submerged breakwaters,
artificial reefs, gravity drain systems, floating breakwaters,
plantations of hydrophylous shrubs or even dry branches, applied
mostly during the past 20 years, are recognised as possessing
technical, environmental and financial advantageous properties
deserving more attention and further developmental experimentation
than has occured hitherto. On the other hand, 'hard' shore
protection methods such as seawalls, groins and detached
breakwaters, artefacts borrowed from port design and construction
technology, no matter how well designed and well implemented they
may be, can hardly avoid intensification of the consequential
erosive, often devastating, effects on the down-drift shores.
Moreover, they often do not constitute environmentally and
financially attractive solutions for long stretches of eroding
shoreline. Engineers and scientists practising design and
implementation of shore defence schemes have been aware for many
years of the public demand for improved shore protection
technologies. They are encouraging efforts that promise enrichment
of those environmentally sound and financially attractive methods
that can be safely applied.
