Flash floods and torrential floods occur frequently in the Brague catchment, the last extremeevent in Oct. 2015 was a large-scale disaster. Located in Southern France, the Brague catchmentis challenged by flood hazards threatening residential and economic areas. Those living in floodproneareas face the risk of severe damage to their infrastructures due to torrential floodseventually aggravated after forest wildfire, and those living outside flooded areas have to copewith runoff hazards. These natural disasters, although they are natural drivers of ecology andgeomorphology, generate large losses to economy and human lives. Flood and fire risk analysiscombined to nature-based solutions (NBS) are an opportunity to reduce vulnerability and toassess the value of NBS. This report aims at presenting the methodology developed in theBrague DEMO to assess the potential efficiency of nature-based solutions. The main strategiesthat will be investigated are a series of NBS spread along the river corridor in the lowlands wherethe largest number of assets and people is concentrated. However, a significant part of thecatchment is still occupied by forests and a study of forest fire hazards and possible cascadingconsequences on floods in the lowlands will also be performed in order to raise the awarenessof the current flood reduction ecosystem service of forests. The report is organized as follows:(i) fire hazards, (ii) hydrology (rainfall and runoff modelling), (iii) hydraulics, (iv) exposure basedon insurance flood claims and (v) integrated flood protection schemes (assessment and portfolio
