| Abstract | Map Ta Phut port is located on the Rayong coastline between Sattahip and Samet
Island which is an open coast exposed to moderate waves generated in the Gulf of Thailand
from the southwest and southeast. The predominant southwest waves prevailing from May
to September provide moderate longshore sand transport from west to east while the smaller
southeast waves prevailing from February to April provide less longshore sand transport
in the opposite direction.
A 4.0 kilometer long breakwater and 1.7 kilometer long groin were constructed on
the western and eastern sides of the port respectively from October 1989 to May 1992. It
was anticipated that accretion would prevail on the west and erosion on the east of the port.
This field monitoring was made to determine rates of accretion and erosion of
shorelines as a result of the ·construction of Map Ta Phut port on Rayong coastline in order
to find appropriate remedy measures especially for eroding zones.
It was found from the study for a period of 2 years from May 1990 to May 1992 that
the dominant southwest monsoon waves generated a net littoral drift from west to east at
a rate of 383,000 m3/year from the rate of shoreline accretion on the west of the breakwater.
Despite the expected dominant erosion on the east side of the port, the shoreline was
found to be less eroding due to the existence of Saket Island and the breakwater which
provided shelter for the shoreline. This is in fact a fortunate circumstance. However, the
monitoring should be continued since the dominant accretion on the west side of the port
should contribute to dominant shoreline erosion on the east of the port which has not yet
been revealed in May 1992. It is seen by eye inspection in May 1993 at the time of. this
reporting that some erosion has occurred on the east of the port. |
