Although known for its natural charm that attracts visitors from abroad, Bali faces major challenges in terms of natural disasters. Recently, Bali was hit by floods caused by prolonged rain. As a result, the infrastructure of buildings has deteriorated due to increased humidity.
An effective solution is needed for flooding in Bali, and geobags could be the answer. This efficient innovation better maintains the sustainability of buildings. Useful for flexible and environmentally friendly water control bags, geobags offer effective protection for flood-prone areas.
This article will explain how geobags can be the best option for flood control, as well as their proven application in several areas in Bali. Here is the full explanation.
What is a Geobag and How Does it Work?
These large bags made of geotextile material are usually filled with sand or soil. The filled geobags are then arranged to form a protective embankment to hold back floodwater.
This geotextile material is highly resistant to erosion and high water pressure. However, water drainage is still possible through the water surface. Therefore, water can still flow safely without damaging the structure.
Geobags work in a very simple way. After being filled with materials such as sand or soil, they are arranged in stacks or barricades to form a retaining wall. Although they provide temporary protection, they are very effective at retaining and diverting water flow. This is an advantage that is needed in areas at risk of severe flooding.
There is no need to worry about installation, as it is quick and easy. This Balinese flood control technology is ideal for short-term disaster management, and even long-term infrastructure.
Another advantage of geobags is their ease of application, even in terrain that is difficult to access with heavy machinery. In addition, geobags can be installed by trained local workers. This can reduce construction costs and time compared to building concrete or stone walls.
The Advantages of Geobags in Flood Management
This effective solution for flood control in Bali was chosen because of its various advantages. First, its flexibility allows it to be adjusted to various shapes and sizes, depending on the needs of the location to be protected. Not only does it prevent flooding, it can also protect homes, infrastructure, and agricultural land. Everything can be easily adjusted to effectively withstand water flow.
The second lies in its raw material, namely geotextile. It is highly resistant to extreme weather conditions, enabling it to last for a long time. In short, geobags are effective at retaining water and are resistant to friction, expansion, and contraction caused by drastic weather changes. For example, intense heat during the day and heavy rain at night.
On the other hand, installing geobags is practical and relatively quick. This is in comparison to building concrete embankments, which are costly. Their practicality is very helpful in emergency situations. Interestingly, geobags can be moved to the required location, due to their non-permanent nature.
Geobag Application in Bali
In several flood mitigation projects in Bali, geobag installation has been successfully implemented. One of these projects was in the coastal area of Monggalan Beach, where geobags were used as embankments to strengthen the coastline. This preventive measure reduces abrasion and tidal flooding. The coastal structure, which is prone to erosion, can be maintained, and settlements near the coast are protected.
In another case, geobags were also used by BPBD or the Bali-Penida Regional Disaster Management Agency. This was part of flood mitigation efforts involving the local community. BPBD also conducted training and installed geobags to maintain the resilience of infrastructure against potential natural disasters. The success of this project proved the effectiveness and durability of the material in dealing with floods.
Geobags are also relied upon in flood control projects in Bali’s agricultural areas. In this case, the bags serve to divert water flows that could damage agricultural land. As a result, agricultural land that was previously threatened by flooding can be protected, thereby better safeguarding food security in Bali.
Geobags have proven to be a highly effective solution for flood control in Bali. Their advantages, made from strong geotextile materials and ease of installation, make them the ideal choice for various flood control projects.
