Abstract: Abstract The conjunct application of various tools, such as collaborative watershed management and strategic planning models, is crucial for monitoring Flood Control and Management Measures (FCMMs). Therefore, this study was carried out with the aim of strategic flood management using collaborative Game Theory (GT) and conjunct application of hydrologic and strategic planning models in the Cheshmeh-Kileh Watershed, Iran. To address this, semi-structured interviews were conducted with key stakeholders to implement strategic planning models and FCMMs. Subsequently, FCMMs were strategically analyzed using SWOT (Strengths, Weaknesses, Opportunities, and Threats) and PESTEL (Political, Economic, Social, Technological, Environmental, and Legal) models. GT was utilized to prioritize these factors, leading to the determination of optimal FCMMs. Critical Sub-Watersheds (SW) were identified to assess the quantitative impacts of FCMMs, followed by quantifying the effects of the proposed measures using the HEC-HMS model. The results indicated that the combined matrix of strategic planning models revealed that the assessment of internal and external factors for nature-based measures, with weights of 3.966 and 1.609 respectively, and for structure-based measures, with weights of − 2.847 and − 3.486, confirmed that nature-based measures were identified as the most optimal choice. The prioritization results of the Sub-Watersheds (SW) indicated that the watershed upstream had a high Flood Generation Potential. The impact of nature-based and structure-based measures on Flood Control and Management (FCM) was observed to decrease. The integrated use of hydrological and strategic planning models demonstrated that nature-based measures in FCM exhibited greater effectiveness. Overall, it can be concluded that these approaches are directly applicable for use by executive managers, policymakers, and decision-makers in FCM.
