Management Strategies For Reduce the Consequences of Flood Hazard with the SWOT Analytical Method (Case Study: Hamedan- Bahar Plain)

   Inadequate productivity and over-capacity of land in many watersheds and plains of the country, has increased flooding potential. Therefore, reducing flood damage with the participation of both policymakers and the public as key stakeholders in decision-making, planning, long-term management and foresight in decisions are unavoidable. In the present study, SWOT analytical method was used to reduce flood potential and reduce flood risks in Hamedan- Bahar plain of Hamedan province in Siminehroud basin. To this end, the strengths, weaknesses, opportunities, threats to the method of precipitation, and the relative and final value of each of the SWOT evaluation matrix factors were assessed to determine the strategy for reducing the consequences of flood hazards. The final value of the matrix of all SWOT factors was 4.47, which indicates that strengths outweigh weaknesses. Also, the final value of external and internal factors was obtained as 2.51 and 1.96, respectively, which indicates that there are more opportunities than threats. These conditions indicate the establishment of a conservative strategy (WO) in the Hamadan-Bahar plain and the use of existing opportunities to reduce weaknesses. Finally, the two strategies of monitoring the construction of river banks and applying expert opinions in the implementation of land management laws along rivers and catchments with a weight of 0.761 ranked first in reducing the flood potential of the plain and reducing flood hazards.
