Monitoring and Modeling of Urban Hydrology - A Case Study of Two Japanese Catchments
by Srikantha Herath, Katumi Musiake, Amila Silva and Sadayuki Hironaka
- Study focuses on modeling the impact of urbanization on the hydrological cycle and assessing the effectiveness of infiltration systems.
- Utilizes a lumped parameter hydrological process model specifically developed for this purpose.
- Applied to a hilly catchment in the outskirts of Tokyo, Japan, undergoing urban development.
- Model parameters derived from various sources such as topographic maps, soil distribution maps, and land use data.
- Compares simulated and measured stream flows to evaluate model performance.
- Conducts simulations to assess changes in the hydrological cycle due to urbanization.
- Explores strategies for restoring the hydrological cycle, including infiltration trenches and retention-infiltration systems.
- Evaluates alternate plans to identify the most effective scheme for restoring the hydrological cycle in the urbanized catchment.
