Summary
An unmanned aerial vehicle (UAV) system effectively inspects riverbanks for garbage, preventing marine pollution. This technology uses advanced path planning and obstacle avoidance for efficient cleanup operations.
Area of Science:
- Environmental Science
- Robotics and Automation
Background:
- Coastal pollution originates primarily from land-based sources.
- Effective management of riverine waste is crucial for maintaining marine ecological health.
- Current inspection methods may lack the efficiency and adaptability needed for complex riverine environments.
Purpose of the Study:
- To develop and evaluate an unmanned aerial vehicle (UAV) system for riverbank inspection and garbage identification.
- To enhance the efficiency and adaptability of UAVs in complex riverine environments through advanced algorithms.
- To facilitate proactive waste management by identifying pollutants before they reach the sea.
Main Methods:
- Utilized an unmanned aerial vehicle (UAV) for autonomous riverbank inspection.
- Implemented Improved Particle Swarm Optimization (IPSO) with a fuzzy system for optimized path planning.
- Integrated an Artificial Potential Field (APF) algorithm for real-time dynamic obstacle avoidance.
Main Results:
- The UAV system successfully performed riverbank inspections in a complex environment.
- Optimized path planning reduced energy consumption and inspection time.
- The obstacle avoidance system effectively navigated environmental challenges like protruding branches.
Conclusions:
- The proposed UAV system offers a viable solution for monitoring and identifying riverbank waste.
- This technology can significantly contribute to preventing marine pollution by enabling timely cleanup.
- The integration of advanced path planning and obstacle avoidance enhances operational efficiency for environmental monitoring.

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

50
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

69
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...
