Simulation of basin scale runoff reduction by infiltration systems
by S. Herath, K. Musiake
- The study Introduces a modeling approach for simulating infiltration systems in urban areas.
- Model comprises a hydrological sub-model and an infiltration system sub-model.
- Richards' equation is used to simulate infiltration characteristics of individual facilities.
- Linear relationships between water head and infiltration rate are determined based on facility width.
- Infiltration system model integrates aggregated facilities with the catchment runoff model.
- Model validation conducted in a residential area with and without infiltration systems.
- Proposed modeling method effectively evaluates infiltration system performance.
- Model parameters derived from physical characteristics of the catchment.
- Comprehensive approach provides insights into infiltration system performance and stormwater runoff impact.
