Title: what is
the better solution of coastal erosion bringing toward sustainability
development.
Introduction
Waves generated
by storms, wind, or fast moving motor craft, cause coastal erosion. Coastal
erosion is a natural process along the world’s coastlines that occurs through
the actions of current and waves. Coastal erosion also is the wearing a
way of land and the removal of beach by wave action, tidal current,
wave currents, or drainage. Coastal erosion is a natural process that becomes a
hazard or problem when it poses that threat to things the human’s value. How to
address coastal erosion is a challenge for government and other agency because
there have many alternative remedial measures. To protect coastal erosion, some
areas need to build fortress to separate the beaches from the effects of the
seas. For example Seawalls and revetments are built to protect the land behind
them. Groins are rock, timber, concrete or metal pilings built perpendicular to
the shore to reduce sediment transport and widen beaches. Besides that, the
offshore breakwaters are offshore rock or concrete armor units are designed to
reduce the wave energy before it reaches the beach. There have many solution
but we don’t know which the better solution are.
Problem statement
According the
Sinar Harian newspaper (2 Mei 2012), Department of Irrigation and Drainage
(DID) are urged to immediately build concrete stone embankment to prevent
further erosion of the sea waves occur in coastal at Jawa village. According to
them, it is urgent because of erosion that occurred more damaging the
structural condition of the coast, especially during the monsoon season and
tide phenomenon. So, the construction of build concrete stone is the one of way
the better solution to apply as sustainable development?
According to
coastal scientist Professor Andrew Short, Australian coast lines rarely need
protecting; rather it is the man-made seawalls, groynes and breakwaters that
actually create the damage as they harden the coastline and interfere with the
natural movement of sand. So, coastal erosion are man-made or naturally
problems?
Objective
1.
To identify the type of coastal
erosion.
2.
To understand the coastal
erosion issue.
3.
To identify the factors and
ways that determine how best to achieve positive environmental outcomes which
preserve the natural character of the coast.
