Project: Assessment and mitigation of storm runoff loads from an informal settlement (slum)
Supervisors: Dr Lee Bryant, Dr Thomas Kjeldsen and Prof Wesaal Khan
One of the biggest global health problems today is that posed by urban conditions, most significantly in developing countries. Within informal settlements the lack of infrastructure including sanitation and sewage facilities can generate serious problems for health and the environment. It is necessary to understand the processes and characteristics of runoff to mitigate health risks from storm runoff and improve sanitation. The aim of this PhD is to examine how anthropogenic and environmental factors influence stormwater runoff quality and quantity during storm events in a South African settlement and improving the understanding of the links between the hydrology, geochemistry and microbiology of runoff. The case study for this research is in Enkanini, Stellenbosch one of the primary informal settlements near Cape Town, South Africa. Two fieldwork sessions in 2016 and 2017, over the summer months of May to September, were undertaken to collect data. Fieldwork included site selection based upon catchment analysis, data collection within the informal settlement and then analysis of water quality (geochemical and microbiological) and water quantity (hydrology) in the labs at Stellenbosch University. This research and work is performed in collaboration between the University of Bath and its international partner Stellenbosch University.
Olivia is a PhD Student on the WISE CDT based at the University of Bath in the Department of Architecture and Civil Engineering. She is part of both the Water, Environment and Infrastructure Resilience (WEIR) research group and the Water Innovation and Research Centre (WIRC).
Olivia studied Geography under an Open Scholarship at Aberystwyth University and gained a First Class (Honours) BSc. Her dissertation developed a risk map of malaria risk in The Gambia, and is the source of her interest in waterborne diseases and natural hazards. During her third year, Olivia studied for a term at UNIS in Svalbard in the Arctic. Her post-graduate study was a Master of Research in The Science of Natural Hazards at the University of Bristol. Fieldwork included studying the natural hazards in Guatemala, followed by research in Ecuador for her dissertation on volcano risk at Cotopaxi Volcano. The data collected during this research formed the basis of a paper published by her supervisors Dr Ryerson Christie and Dr Joachim Gottsmann (University of Bristol).
Since graduating from Bristol she has gained further experience by working on the Apolline Project, a multi-disciplinary research project in Naples, looking at volcanic deposits and four months spent as a Research Assistant at the Centre of Exchange and Research in Volcanology at the University of Colima, Mexico undertaking data collection, analysis and report writing on volcanoes in the region.
