Green Roof Research Opportunities

Hydrology/Urban Drainage

The following topics are currently available for PhD research in the Department of Civil and Structural Engineering at The University of Sheffield. These projects are unfunded, but we can assist strong applicants to find appropriate scholarships. We would normally only consider applicants with the equivalent of a First Class Honours undergraduate degree and/or a Distinction at Masters level in relevant subjects (e.g. Civil Engineering, Geography), but please contact us if you feel you have other relevant skills and experience. You are welcome to propose alternative research project titles if you feel you have other ideas that complement our existing research activities. For informal enquiries please contact Virginia Stovin. If you wish to make a formal application to the University, please use the on-line application form.

As a PhD student you will have the opportunity to become part of both the Pennine Water Group and the Green Roof Centre, providing excellent opportunities to interact with a wide range of relevant research disciplines.

For informal enquiries relating to research opportunities, please contact Dr Virginia Stovin.

Retention and Detention Performance of Green Roof Substrates

From a stormwater management (urban drainage) perspective, it is essential to be able to predict how a specific green roof installation will respond (i.e. the amount and timing of runoff) to a specific (design) storm event. The roof’s response is affected by various components, including the plants, the substrate and the underlying drainage layer. This research project will focus on substrate, and will explore interactions between the physical characteristics of the material (grain and pore size distributions, % organic, moisture holding capacity) and its hydrological behaviour. The research will predominantly use laboratory rainfall simulator tests to quantify the hydrological response, although data from long-term monitoring of external test beds will also be used to validate and extend the findings.

This project would suit someone with an interest in laboratory analysis and monitoring.

A Generic Model for Green Roof Rainfall-Runoff

From a stormwater management (urban drainage) perspective, it is essential to be able to predict how a specific green roof installation will respond (i.e. the amount and timing of runoff) to a specific (design) storm event. The roof’s response is affected by various system components, including the plants, the substrate and the underlying drainage layer. In recent years, many researchers have published findings relating to specific green roof installations operating within specific climatic environments. The aim of this research project will be to bring these various independent research activities together using consistent performance criteria to explain how roof configuration and climatic conditions affect the roof’s hydrological performance. The research will aim to identify appropriate parameters for input into a simple hydrological modelling tool (based on initial losses and reservoir routing concepts), which will then enable roof performance under different climatic inputs to be simulated.

This project would suit someone with an interest in data analysis and modelling.
