Interaction between hydrologic variability and the macrophyte assemblage within urban waterways


This project aims to improve our understanding of the long term interaction between vegetation and hydrology in wetlands. The mathematical models to be developed in this research project enable us to predict the response of vegetation groups, and consequently develop criteria for better design of urban waterways.

Why my research is important

The dynamic interaction between vegetation and hydrodynamic processes in wetlands and urban waterways has implications for the long-term partitioning of vegetation and subsequent performance of the system. For example, the nature of the vegetation assemblage affects the capacity of the system for nutrient uptake, flood attenuation and habitat creation. Hydrodynamic processes such as the drag force may affect the persistence of certain species, which in turn affects their competitiveness and partitioning within the larger wetland ecosystem. On the other hand, macrophyte presence can impact wetland hydrology and biogeochemistry. The multiple feedbacks between hydrology, macrophytes and water quality remain poorly explored in the context of constructed wetlands, and there is a need for improved understanding of the effect of this dynamic interaction between vegetation and hydrology on the long-term performance of these systems in order to aid urban waterway design. In order to understand this interaction, an interdisciplinary study of hydrology, biogeochemistry and ecology, and incorporation of them into a modelling platform, is essential. To date there have been many mathematical models developed to explore different components of aquatic ecosystems, including lakes and wetlands, however improvements are required to wetland models to allow us to simulate the dynamic interaction between hydrology, vegetation and water quality, and how their performance changes over time.
