PUTRAJAYA – The Natural Resources and Environment Ministry through the Department of Irrigation and Drainage (DID) plans to upgrade bunds along the Selangor coastal areas to resolve flooding caused by the high-tide phenomenon.
Its minister Datuk Seri Wan Junaidi Tuanku Jaafar said the coastal bunds and erosion prevention structures were to stop seawater moving inland especially during the high-tide phenomenon.
However, he said, the global rise in sea-levels meant existing bunds could not stop the seawater.
“The ministry through the DID will take appropriate action with the state government to resolve the flood problem which hit Selangor’s coastal areas following the recent high-tide phenomenon.
“DID plans to upgrade the bunds along the Selangor coastline according to the allocation and this matter will be taken to the Cabinet so that it will get special attention,” he said in a statement here today.
Wan Junaidi said in general, the tidal range varied in different coastal areas of Malaysia, ranging from 1.8 metres to 6.1 metres.
The areas which had high tidal range and low topography were more likely to be submerged during high tide and areas along the west coast of Peninsular Malaysia were generally sloping and low, he said.
“The (flooding) incident was concentrated along the west coast, especially the coast of Selangor because the geographical location was most affected by the high-tide phenomenon,” he said.
He added that according to the data analysis issued by the Department of Surveying and Mapping this year and compared to the findings by Google Play Tide Forecast which applies the Permanent Service for Mean Sea Level (PSMSL) data, the full moon phase was between Sept 16 to 20.
He said the water level could be influenced by the high-tide phenomenon, strong waves, storm surge and strong winds, causing it to exceed the bund height and water to overflow onto the land, causing floods.
As preparation for floods, Wan Junaidi said the DID was ready to provide information of tide schedules to all irrigation canal gatekeepers to control water flow, prepare DID pumps to flush out floodwaters.
“The information and announcement about the possibility of floods as well as information of tide schedules will be passed on to the relevant agencies and early efforts such as maintenance and improvement of the irrigation system under the DID will be carried out to tackle floods,” he said. – BERNAMA
