Abstract: Urban stormwater runoff is a primary degrader of stream ecosystems.Excess stormwater runoff causes altered flow regimes, reduced in-stream water quality, and modified channel form.Recognition of such impacts has renewed interest in the protection or restoration of the hydrologic cycle in urban stormwater management.One of the greatest unknowns, however, is how the urban stormwater impacts on the flow regime translates to hydraulic conditions in the channel.This understanding is critical to identifying how the hydraulic environment supports complex and dynamic ecosystem functioning.My thesis investigates how the flow regime and channel form, and their interactions, deliver in-stream hydraulic outcomes for urban streams.I use hydrodynamic modelling (TUFLOW) to predict hydraulic outcomes, with the models developed using hydrographic and topographic data from two streams in the Melbourne region.A good support system is critical to surviving and staying sane in grad school.It has been a great experience and a wonderful privilege to have been part of WERG, the GOAT (greatest of all time) research group.It was always a joy to come to work because of the wonderful people and the amazing environment created in this research group.I am grateful for the friendship, love and all the wonderful memories.The daily quiz time during lunch was amazing, although I could not answer most of the questions about Africa.I still get a laugh when I reminisce about Tim wondering if I am even from that continent for not getting the answers.I owe special thanks to Rob James, Peter Poeslma and Mike Sammonds for their valuable assistance with fieldwork.Mike, it was a pleasure to always talk (and sometimes argue) about sports (soccer).I hope Liverpool wins the English premiership this year to give you some joy after more than two decades of disappointment.
