Summary
Constructed wetlands and media filters effectively treat nonpoint source pollution in Korea
Area of Science:
- Environmental Engineering
- Water Resource Management
- Pollution Control
Background:
- Nonpoint source pollution is a significant threat to aquatic environments in Korea's major river basins.
- Numerous best management practices (BMPs) have been implemented to mitigate this pollution.
Purpose of the Study:
- To evaluate and compare the performance and cost-effectiveness of various BMPs for nonpoint source pollution control.
- To identify the most suitable treatment options based on a comprehensive analysis of efficiency and expenses.
Main Methods:
- Monitoring and maintenance data from 2005 to 2012 were analyzed for facilities including grassed swales, constructed wetlands, vegetated filter strips, hydrodynamic separators, media filters, and infiltration trenches.
- Performance in pollutant removal and associated construction and operational costs were compared across different BMP categories.
Main Results:
- Constructed wetlands, media filters, and infiltration trenches demonstrated superior pollutant removal capabilities.
- Media filters incurred the highest construction and operational costs.
- Constructed wetlands offered the lowest operational costs and effectively managed runoff quantity, indicating cost does not always correlate with performance.
Conclusions:
- The selection of BMPs for stormwater runoff management should prioritize a balanced consideration of both treatment performance and economic factors.
- Cost-effective solutions like constructed wetlands can provide efficient pollution control and runoff management.

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...
Design Example: Analyzing Capacity Contours for Flood Risk Assessment
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...
Design Example: Managing Concrete Workability
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.
