THE FUTURE CHALLENGE

Generally the aim of the Sabo-Techno application is to control debris mass movement (sediment and other detritus) by REDUCING, CONTROLLING and PREVENTING its power in causing disaster and property losses, and also saving people lives. Despite that, it is not realized that at the same Sabo structure will give contribution on raising the ground water table in order to fill up the aquifer as SAND FILLED RESERVOIR.

The forestation or regreening activity also can be categorized as one of Sabo activities. The principle of natural disaster counter measures that is caused by the debris mass movement is to control the mass movement debris so that it will not cause damages or dangerous to the communities. Deforestation is one causes of debris mass movement. In the well-vegetative covering mountains area, the run-off coefficient and erosion tend to decrease so that the mass movement debris will be reduced. Therefore, Sabo-Techno is combination between the work vegetation and civil engineering. That is why it is called as synthetic technology that was appropriate applied in order to deals with the natural disaster such as debris mass movement.

The debris mass movement does not always move from upstream to downstream. The TSUNAMI disaster that happened at the end of 2004 was also debris mass movement that was very extraordinary, where the current moved from lower to the upstream by the crashing of the tidal wave. Debris and the other detritus that were carried also caused serious damage in river basin area, contaminated fresh water sources including its infrastructure, and disrupted the provisions of clean water for community. Sediment debris (sediment and other detritus) inundation on the rivers had been reduced the capacity of the river channel. This condition was very dangerous and potential caused the secondary disaster such as flood or debris mass movement. The impact of tidal wave and debris flow inundation were also damage irrigation facilities. It also destroyed ecosystem in along coastal area. It is the future challenge for the next Sabo-Techno improvement.

As the front counter of sediment-related disaster, Sabo works can be classified into three counter areas :HILLSIDE SABO WORKS in upstream area, TORRENT SABO WORK in transition area, and COASTAL SABO WORKS in downstream/coastal area. Today the implementation of the Sabo works is limited on hillside and torrent Sabo works. It is the new challenge for The Experimental Station for Sabo as research institution to expand Sabo-Techno application in disaster counter measures, especially in coastal area in order to prevent abrasion and tsunami.
