Summary
This study introduces AvDren, a software tool simplifying urban stormwater management. It aids decision-makers in evaluating and comparing drainage systems with Best Management Practices (BMPs) across various factors.
Area of Science:
- Environmental Engineering
- Urban Planning
- Water Resource Management
Background:
- Urban stormwater system design is complex, especially when incorporating Best Management Practices (BMPs).
- Traditional drainage design often relies solely on pipe techniques.
- Evaluating multiple design aspects simultaneously presents a significant challenge.
Purpose of the Study:
- To present a decision aid methodology and software (AvDren) for urban stormwater systems.
- To facilitate the evaluation and comparison of drainage scenarios using BMPs.
- To support decision-makers in selecting appropriate alternatives and planning investments, particularly in developing countries.
Main Methods:
- Development of a simple decision aid methodology.
- Creation of the AvDren software tool.
- Evaluation of drainage scenarios based on technical, sanitary, social, environmental, and economic criteria.
Main Results:
- AvDren provides a structured approach to compare diverse drainage scenarios.
- The software integrates multiple assessment criteria for comprehensive evaluation.
- It offers a practical tool for informed decision-making in urban stormwater management.
Conclusions:
- The AvDren tool simplifies the complex process of designing urban stormwater systems with BMPs.
- It is particularly valuable for developing countries facing sanitation issues and budget constraints.
- The methodology aids in selecting optimal drainage solutions and planning investments effectively.
