Summary
This study introduces an electric unmanned surface vehicle (USV) for efficient river and lake water quality monitoring. The autonomous USV reduces labor costs and improves pollution detection accuracy, supporting sustainable water management.
Area of Science:
- Environmental Science
- Robotics
- Sensor Technology
Background:
- Industrialization has intensified river pollution, necessitating advanced detection methods.
- Traditional water quality monitoring is labor-intensive, costly, and time-consuming.
- Existing methods struggle with prompt and effective river pollution detection.
Purpose of the Study:
- To develop and demonstrate an autonomous unmanned surface vehicle (USV) for remote water quality detection.
- To replace manual sampling with an efficient, cost-effective, and unmanned solution.
- To enhance the accuracy and timeliness of river and lake pollution monitoring.
Main Methods:
- An electric USV equipped with GPS, AIS, and wireless data transmission was utilized.
- The USV autonomously navigated pre-defined routes for water quality measurements.
- Integrated sensors measured pH, dissolved oxygen (DO), electrical conductivity (EC), and oxidation-reduction potential (ORP).
Main Results:
- The USV demonstrated precise positioning and autonomous navigation capabilities.
- Real-time water quality data effectively indicated pollution levels.
- The system successfully identified collision risks using AIS for safe route planning.
Conclusions:
- The autonomous USV offers a significant improvement over traditional methods for water quality monitoring.
- This technology reduces operational costs and labor requirements in environmental monitoring.
- The developed system contributes to achieving UN Sustainable Development Goal 14 (Life Below Water).

Testing Water Quality

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Buoyancy and Stability for Submerged and Floating Bodies
2.0K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Quality of Water
195
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
