Exploring Underwater Intricacies: Utilising Drones to Assess Marine Ecosystem Impact from Dike Construction

The rise of drone technology now offers unprecedented possibilities for exploring and monitoring the most inaccessible environments. Underwater drones, in particular, have become valuable tools in the study and monitoring of marine ecosystems. Their use in infrastructure projects such as the construction of dikes represents an innovative method for ensuring the preservation of marine ecosystems affected by these major works. This article offers an immersion in the techniques for using underwater drones to monitor the impact of dike construction on aquatic life.

Understanding the impact of dike construction

Understanding the impact of dike construction

Even before deploying underwater drones, it is essential to understand the challenge of building dikes in aquatic environments. Sea walls, designed to protect coastal areas from flooding and erosion, can alter currents, deposit sediment in new locations and potentially destroy habitats. Scientists and engineers responsible for environmental monitoring rely on a variety of methods to understand and mitigate these effects.

Underwater drone technology

Features and functionality

Underwater drones, also called ROVs (Remotely Operated Vehicles), are equipped with high definition cameras, sonars, sensors capable of measuring different physicochemical parameters (such as temperature, salinity and turbidity of water) and sometimes arms manipulators. These machines can dive to depths unreachable by humans and remain submerged for hours or days, providing valuable data in real time or recorded for later analysis.

Configuration and implementation

Preparing for an underwater drone mission requires careful programming of flight parameters, tailored to the specific mission objectives. This includes the definition of the route, the working depth, the cruising speed, as well as the data collection methods.

Environmental monitoring protocol with underwater drones

Preparatory phase

The success of an ecological monitoring mission begins with an identification phase. It is essential to conduct studies to identify risk areas and determine drone routes. Preliminary dives with reconnaissance drones can be useful to provide background mapping before installing the dike. This step makes it possible to evaluate the underwater topography and identify the biological characteristics of the ecosystem to be protected.

Data collection during construction

During the construction of the dike, regular monitoring is necessary to control changes made to the environment. The drone is then deployed to observe the evolution of sediments, the dispersion of particles and changes in habitats. Captured images and videos provide visual evidence, while sensor data enables quantitative analyses.

Post-construction analysis

After construction, monitoring continues to assess long-term effects. Inspection sequences reproduced at regular intervals can reveal trends and developments in the marine environment. Post-construction analyzes are crucial to detect unanticipated impacts and require special attention.

Advantages of using underwater drones

The mobility offered by underwater drones allows you to reach areas that were previously difficult to access. Their ability to collect large amounts of data accurately and in a short period of time improves understanding of environmental impacts while reducing the costs and risks associated with human diving.

Reduce human intrusion is another notable advantage. Drones cause much less disruption to marine life than divers or manned submarines, providing a more environmentally friendly approach to studies at sea.

Recent developments and prospects

The current trend is the integration of artificial intelligence in underwater drones. This allows increased autonomy, better interpretation of the data collected and the ability to adapt interactively with the environment. Advances in sustainability and energy efficiency also promise to increase mission longevity.

Ethical and regulatory considerations

Protection of privacy and conservation of natural spaces are primary considerations when using underwater drones. Compliance with local and international regulations regarding surveillance and research is the responsibility of every user of this technology.

Examples and case studies

International projects have already demonstrated the usefulness of underwater drones. Case studies, such as monitoring coral reefs around seawall construction areas in Southeast Asia, have shown adjustments in engineering and methodology to minimize environmental impact. These examples are instructive for future projects and highlight best practices in the use of underwater drones.

Training and skills needed

Handling underwater drones requires a combination of engineering, robotics and marine biology skills. Operators must be trained in the use of these complex systems and be made aware of the ecological issues linked to the study areas.

Interdisciplinary collaboration

Environmental monitoring by underwater drone cannot be a success without close collaboration between engineers, marine biologists, ecologists and other stakeholders. This synergy between disciplines is crucial to maximize the effectiveness of monitoring and to guarantee interventions that respect the ecosystems studied.

The application of underwater drones in monitoring the effects of dike construction on marine ecosystems constitutes a bridge between technology and the environment. Although the article refrains from formulating a conclusion, it is clear that underwater drones have a leading place in the protection of marine environments affected by human activity. Thanks to their precision, discretion and versatility, these devices are emerging as essential allies in the quest for sustainable development and harmonious coexistence with the treasures of the oceans.
