Eco-Friendly Technology to Prevent Floods
Biopores and Infiltration Wells as Natural Solutions
Environmentally friendly technology to prevent flooding is increasingly needed, especially in urban areas experiencing shrinking green areas. One effective method is the use of biopores and infiltration wells. Biopores are small holes made in the ground to increase air absorption, so that rainwater does not flow directly to the surface but seeps into the ground. Infiltration wells have a similar function, namely to collect rainwater so that it is absorbed into the ground slowly.
The application of biopores and infiltration wells is highly recommended in areas with high rainfall and minimal infiltration areas. With this method, rainwater does not directly enter the drainage channels which can cause overflow and accumulation. Big cities that implement this system have been proven to be able to reduce the risk of flooding significantly. In addition, biopores also help improve soil structure and increase fertility because organic waste that is put into it will decompose into natural compost.
Permeable Pavement to Reduce Waterlogging
In an effort to implement environmentally friendly technology to prevent flooding, the use of permeable pavement or porous pavement is an effective solution. This material allows rainwater to seep directly into the ground, replacing conventional asphalt or concrete that usually inhibits air absorption. With this technology, air no longer flows freely on the surface, but instead goes directly into the ground, reducing the risk of puddles and flooding.
In addition, permeable pavement also helps reduce the temperature of the road surface because the material used has a lower heat absorption capacity than ordinary concrete. Several developed countries such as Japan and the Netherlands have applied this technology to sidewalks, parking lots, and small roads to reduce the impact of urban flooding. In Indonesia, the application of technology is still limited, but it has begun to be introduced in several green city development projects.
Green Roofs and Vertical Gardens to Absorb Rainwater
Environmentally friendly technology to prevent flooding can also be applied through green roofs and vertical gardens. This concept relies on plants planted on building roofs or vertical walls to absorb rainwater before it reaches the ground. In addition, green roofs can reduce the urban heat island (UHI) effect, which often worsens flooding conditions in big cities.
Vertical gardens and green roofs not only provide ecological benefits, but also aesthetics. With plants growing in buildings, the air becomes fresher, and humidity can be maintained. In several big cities such as Singapore and New York, this concept has become part of sustainable development. In Indonesia, several office buildings and environmental centers have begun to implement this concept as a form of concern for the environment.
Nature-Based Drainage System to Control Water Flow
Poor rainwater management is often the main cause of flooding in urban areas. Therefore, environmentally friendly technology to prevent flooding can be applied by building a nature-based drainage system. This concept imitates natural ecosystems, such as artificial swamps, green canals, and retention ponds, which function to hold and slow down the flow of water before it reaches rivers or main channels.
The application of a nature-based drainage system is very effective in controlling flooding because it allows water to flow more naturally and does not directly enter the urban drainage system which is often overcapacity. In addition, this system also increases biodiversity by providing habitat for various species of flora and fauna that live in water areas.
AI-Based Early Warning System for Flood Prediction
Modern technology based on artificial intelligence (AI) also plays an important role in creating environmentally friendly technology to prevent flooding. The AI-based early warning system is able to analyze rainfall data, river water levels, and soil conditions to provide more accurate flood predictions. With this system, the government and the community can take preventive measures faster before flooding occurs.
Many developed countries have implemented this system by integrating sensors spread across strategic points. Data from these sensors are collected and analyzed in real-time using sophisticated AI algorithms. With the rapid development of technology, it is hoped that this system can be implemented more widely in Indonesia to reduce the risk of flooding.
Urban Forests and Green Belts as Natural Flood Restraints
Urban forests and green belts are one of the natural strategies in implementing environmentally friendly technology to prevent flooding. Trees in urban forests have the ability to absorb rainwater significantly, so they can reduce the amount of water that flows directly to the ground surface. In addition, plant roots also function to hold the soil so that it is not easily eroded by water flow.
Green belts created along river basins or coastal areas can function as natural barriers against flooding and abrasion. Vegetation planted in green belts helps stabilize aquatic ecosystems and reduces the impact of flooding that can occur due to high rainfall or rising sea levels. The implementation of this concept is not only beneficial for the environment, but also for public health because it improves air quality and reduces pollution.
Utilization of IoT Technology in Flood Control
The Internet of Things (IoT) is one of the important innovations in creating environmentally friendly technology to prevent flooding. By utilizing smart sensors and IoT devices, monitoring of weather conditions, river water levels, and drainage systems can be done in real-time. Information collected from these IoT devices can be used by the government and the community to take appropriate preventive measures before flooding occurs.
Several cities in the world have implemented this system by connecting IoT devices to a control center that manages data automatically. For example, if the system detects a significant increase in rainfall, an early warning will be sent to the community via an application or social media. This allows residents to evacuate early and significantly reduce the impact of flooding.
The Role of the Community and Collaboration in the Implementation of Environmentally Friendly Technology
In addition to implementing various environmentally friendly technologies to prevent flooding, community involvement is also a key factor in its success. Public awareness not to litter and to protect the surrounding environment can help reduce the risk of flooding. Educational programs on the importance of green technology must continue to be carried out so that more parties are involved in disaster mitigation efforts.
The government, private sector, and environmental communities must also collaborate in developing and implementing this technology more widely. With synergy between various parties, flood prevention measures based on environmentally friendly technology can be more effective and sustainable.
