In an effort to reduce the impact caused by natural disasters, it is necessary to have disaster mitigation. Making maps of flood-prone zones is one form of non-structural mitigation. The purpose of this study was to determine the zoning level of flood vulnerability, design a dynamic model of flood vulnerability, and develop a floodprone area policy in Limapuluh Kota Regency, West Sumatra Province. The method used for the manufacture of flood-prone zones using a geographic information system (GIS) using GIS 10.1 software, then to determine dynamic modeling using a systems approach analyzed with powersim 10. Conclusion 1) Land use for gambir plants (Uncaria Gambir) has a large impact against floods. The mining activities of the excavated land also have a significant effect on the increase in flood disasters. 2) The study area consisted of three flood-prone zones, namely high vulnerability, 6.2% of the total area, prone zones while 50.6% zones were around 43.2% low hazard zonesotherflood-prone zonesdynamic modelspolicy directions
