Tidal Bore

Tidal bore is a natural phenomenon at Bt Lupar or Lupar River in Sri Aman. Tidal bore occurs due to the rapid rise in water level during the tide. During certain time of the year, the tidal bore is very huge and during that time boat regatta were usually being held annually.

Tidal bore occurs twice a day. Last weekend, the tidal bore occurred at 5 pm in the afternoon and at 8 am in the morning where the following pictures were taken.

As a result of the constant pounding of the tidal bores, the riverbank erosion is a unique problem that need to be tackled by the local authorities. Most of the structures built along the riverbank unless the foundation is solid rock are being eroded into the river.

The following picture shows the approaching tidal bore.

In order to prevent their boat from being damaged by the tidal bore, the boat owner will prefer to have the tidal bore ride as shown in the following picture. Small boat or ships also will have to move away from the wharf in order not to damage the structure during the tidal bore.
