Summary
This study uses System Dynamics to model urban flood risk, integrating social and hydrological factors. It highlights Blue-Green Infrastructure
Area of Science:
- Urban systems analysis
- Environmental engineering
- Socio-hydrology
Background:
- Urban flooding is a growing challenge due to climate change, urbanization, and aging infrastructure.
- Traditional hydrological models inadequately capture the complex interplay of urban systems, hindering effective flood risk management.
- Socio-hydrological modelling offers a complementary approach by integrating social and hydrological processes for enhanced flood resilience understanding.
Purpose of the Study:
- To propose and apply a participatory socio-hydrological modelling approach using System Dynamics (SD).
- To quantitatively analyze the feedback between flood risk and urban system components.
- To evaluate the role of Blue-Green Infrastructure (BGI) in urban flood resilience.
Main Methods:
- Participatory socio-hydrological modelling based on System Dynamics (SD).
- Integration of scientific expertise with stakeholder knowledge for model development.
- Quantitative analysis of interactions between flood risk reduction measures and urban sub-systems.
Main Results:
- SD quantitative modelling provides actionable insights into flood risk and resilience for decision-makers.
- Combining scientific and stakeholder knowledge enhances model tailoring and identifies effective resilience measures.
- Blue-Green Infrastructure (BGI) offers hydrological, social, and environmental co-benefits, especially when integrated with grey infrastructure.
Conclusions:
- Socio-hydrological modelling, particularly with SD, is crucial for understanding complex urban flood dynamics.
- Participatory approaches and stakeholder engagement significantly improve flood risk management strategies.
- Blue-Green Infrastructure presents a multi-benefit solution for enhancing urban flood resilience and sustainability.

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.

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
