Implementing green infrastructure in retrofit projects to reduce flooding and pollution is a significant challenge in space-constrained and overdeveloped communities that also have complex underground utility systems.
To overcome this challenge, researchers have developed an adaptive green infrastructure toolkit that can be adjusted according to both the spatial size above ground and the depth of obstacles below ground.
The study, titled “Adaptation Toolkit for Predicting the Impact of Green Infrastructure Development on Stormwater Runoff and Pollution Loads—A Case Study of the City of Galena Park, Texas, USA,” published in the diary of Frontier of landscape architecture.
This study evaluates the effectiveness of this toolkit in mitigating flooding and non-point source pollutants by demonstrating the case of the city of Galena Park, Texas, USA, which suffers from severe flooding and above- and below-ground space constraints. It is intended to. problem.
The researchers first applied the toolkit to create a master plan for Garena Park, using a Delft3D-FM (flexible mesh) flood model in conjunction with a long-term hydrological impact assessment (L-THIA) model to refine the plan. We evaluated the effectiveness.
The results show a gradual decrease in stormwater runoff and NPS pollutants across different stages. These findings highlight the effectiveness of the toolkit in improving water management and pollution control and provide valuable empirical evidence for similar communities facing similar challenges.
