Abstract: Abstract This investigation aims to identify, prioritize, and determine the trend of changes in the factors affecting flood potential in the Khorramabad watershed in Iran; propose and evaluate appropriate management solutions to mitigate driving forces and pressures; and utilize the DPSIR framework to improve the state and reduce the relevant impacts. For this purpose, we quantified several indicators and criteria for each component of a conceptual cause–effect relationship diagram. According to the findings, climate change (with an average rank of 2.93), population pressure (~ 2.78), and traditional animal husbandry (~ 2.45) are the most influential factors influencing the occurrence of flooding in this watershed. The combination of flood risk factors has resulted in a significant increase in runoff production and consequently in flood discharge in the region. The results of this study indicate that: (a) there has been an upward trend in flood occurrence; (b) the pressure caused by the driving forces is intensifying; (c) the ability of managers to control the driving force is extremely limited; and d) the introduced policies have failed to mitigate flood risk.
