Sanur Beach is implemented along the beach of approx 6-7 km between Grand Bali Beach and Serangan Area. Before, the beach and the hotel are naturally protected from erosion by nearly continuous parallel ridge of coral lying just offshore. In the more-less 500 m space between the coral ridge and the beach, there is very shallow tidal lagoon, which is rich in sea life and which dampens the force of waves coming over the reef top.
There are many coastal protection structure like groin and seawall have been made along the coast by the owner of the properties to protect their own area, which finally led to an unnatural beach and degraded the coastal and recreational amenity value and the natural character has been severely degraded. All of the structures. Only beach in from of Bali Beach Hyatt Hotel (almost 1 km) are still preserved without any coastal protection. This is shown the effectiveness of natural offshore reefs to absorb and attenuate the wave energy before reaching the beachfront.
More than 30 m of shoreline retreat has occurred since 1983 due to the destruction of the coral reefs by mining, beach sand extraction and man made channel cut through the reef and pollution. According to function of the beach, shore protection work for Sanur Beach need to fulfils the following requirements:
- Protect the beach and reduce erosion
- Provide a wide beach and a safe swimming area
- Maintain good aesthetic effect
- Religious activity for Hindu people
After desire the required situation, some alternative can be making base on feasibility studies and existing investigated reports. Shoreline retreat has occurred due to the destruction of the coral reefs by mining, beach sand extraction and man made channel cut through the reef. They are many fishermen broken the coral reef to make canal. This is made the effectiveness of natural offshore reefs reduce to absorb and attenuate the wave energy before reaching the beachfront.
When the coral was removed, stronger wave came through the lagoon, presumably eroding the beachfront and making certain parts of the beach unsuitable for tourist use. Beside that, lowering of the lagoon give effect to an increased beach slope caused some slump of beach sand into the lagoon.
The immediate reaction of many tourist hotel owner was protected their own area without coordinate. The owner of the properties has made coastal protection structures like groin and seawall/riprap along the coast. This is caused new and difference problem, like total loss of adjacent and down current beach at some site. Which finally led to an unnatural beach and degraded the coastal and recreational amenity value and the natural character has been severely degraded.
