Integrating non-market values in economic analysis of flood mitigation options: a case study of the Brown Hill and Keswick creeks catchment in Adelaide Morteza Chalak, Veronique Florec, Atakelty Hailu, Fiona Gibson and David Pannell Abstract: This study undertakes an economic analysis of flood mitigation options for a high flood risk catchment in Adelaide, South Australia: the Brown Hill and Keswick creeks catchment. Several proposals for flood mitigation investments have been presented, including creek capacity upgrades, high flow bypass culverts and detention dams. For flood managers to know which option or options provide the best value for money, it is necessary to compare the costs and the benefits of all available options. To date, economic analyses have focused primarily on estimating the tangible (market) costs and benefits of mitigation strategies, but have largely ignored the intangible (non-market) costs and benefits.
