10. Why are you here? Flooding influences the way I perform part of my job Flood management responsibilities will affect my role in future I’m concerned about flooding I need to know more My boss told me to come… It’s a morning out of the office, isn’t it?…

11. Etiquette Flooding is traumatic, and wrecks lives. People may die. Recognise that we are talking about an emotional issue, but that as professionals we need to be as rational as possible in our approach. We may also be amused at times. Ask questions – participate Talk to new people Discuss everything Make notes if you wish. Handouts will be available No mobiles or BlackBerries, please!

12. ‘Wicked’ problems… Are poorly formulated and complex With interconnected physical/scientific and human/sociological dimensions… Where what happens in one place and time affects what happens somewhere else, at a different time Involving many different stakeholders… Who don’t agree about what is important… And who use the terminology in different ways… And who cannot agree if the problem has been solved Solutions are usually ‘better’ or ‘worse’ rather than absolute, and yet decisions must nevertheless be made in the light of uncertainty. ‘Wicked problems’ defy traditional linear solutions, requiring more adaptable ways of thinking. Based on Rittel and Webber, 1973
