The risk of flooding is the main natural hazard that affects the European Mediterranean region. This hazard has worsened in recent decades due to the occupation of flood areas and the effects of climate change. Therefore, understanding and gaining a more in-depth knowledge of social representations of flooding is important. In addition, interest in this subject is accentuated in the case of future teachers. This is because it is mandatory to teach this subject in Primary Education (Grades 1-6; Social Sciences subject). The aims of this research are: (1) To explore the instruction about flooding received by future teachers during their school period, and (2) to examine their perception about factors influencing flood risk. Methodologically, a questionnaire was distributed among future teachers of Primary Education (Faculty of Teaching Training, University of Valencia, Spain). The results regarding the respondents' perception show that only 21.3% of the future teachers received instruction about floods during their school period. With reference to factors that influence floods, they mostly believe that the main factors are climate change and the spatial land management. Furthermore, 51.3% believe that this phenomenon has been increasing over the last few years, and 82.5% think that it rains heavier today
