Summary
Urbanization increases flood risk by reducing natural water storage. Protecting stormwater corridors and connecting green spaces enhances urban flood resilience and supports sponge city goals.
Area of Science:
- Environmental Science
- Urban Planning
- Hydrology
Background:
- Rapid urbanization leads to hardened surfaces and reduced land for water storage, diminishing urban stormwater control capabilities.
- Increased frequency of flood disasters highlights the conflict between urban development and stormwater safety.
- Construction land often encroaches on natural rainwater confluence areas, exacerbating urban waterlogging issues.
Purpose of the Study:
- To analyze the rain and flood safety patterns in Harbin's central city.
- To propose optimization strategies for coordinating water ecosystem services with socio-economic development.
- To enhance urban resilience against rainstorm risks and reduce waterlogging disasters.
Main Methods:
- Spatial analysis using ArcGIS.
- Hydrological modeling with the Soil Conservation Service (SCS) model.
- Evaluation of rain and flood safety patterns.
Main Results:
- Protecting original stormwater corridors is crucial for maintaining connectivity.
- Strengthening connections between stormwater control patches builds natural regulation and storage systems.
- Effective strategies can significantly increase a city's resistance to rainstorm risks.
Conclusions:
- Preserving and enhancing natural stormwater infrastructure is key to mitigating urban flooding.
- Integrating ecological principles into urban planning is essential for sustainable development.
- The study provides a framework for achieving sponge city objectives and improving urban water management.

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.

Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...
