چکیده
سیل یکی از مهم‌ترین بلایای طبیعی است که تأثیرات گسترده‌ای بر مناطق مختلف ایران، به‌ویژه شهرستان کاشان، دارد. این پدیده سالانه خسارات مالی قابل‌توجهی به زیرساخت‌های منطقه وارد کرده و منجر به آسیب‌های جانی نیز می‌شود. با توجه به اهمیت این موضوع، شناسایی و ارزیابی مناطق سیل‌خیز می‌تواند نقش مؤثری در کاهش خسارات و پیشگیری از اثرات مخرب سیلاب ایفا کند. بر این‌ اساس، این پژوهش به پهنه‌بندی سیل‌خیزی شهرستان کاشان در مرکز ایران پرداخت. در این پژوهش، از سیستم اطلاعات جغرافیایی به‌عنوان ابزاری کارآمد استفاده شد. در گام نخست، نقشه‌های رستری مرتبط با شاخص‌های مهم و تأثیرگذار بر سیل‌خیزی منطقه تهیه شد. این شاخص‌ها شامل متغیرهای محیطی و جغرافیایی مؤثر بر وقوع سیل هستند. سپس، این نقشه‌ها با استفاده از روش تحلیل سلسله مراتبی به‌عنوان یکی از روش‌های وزن‌دهی مناسب تحلیل شد و وزن‌های هر معیار و طبقه‌های مرتبط با آن‌ها مشخص شد. درنهایت، نقشه نهایی پهنه‌های سیل‌خیز با بهره‌گیری از ابزار محاسبه‌گر رستر در محیط GIS تولید شد. یافته‌ها نشان داد که حدود 30 درصد از مساحت شهرستان در پهنه با بیشترین خطر وقوع سیلاب قرار دارد؛ این بخش عمدتاً شامل نواحی شرقی با تراکم بالای جمعیت و توسعه شهری است. در مقابل، حدود ۶۰ درصد از مساحت شهرستان در پهنه با کمترین خطر وقوع سیلاب جای می‌گیرد که بیشتر در مناطق غربی با شیب ملایم و تراکم بالای پوشش گیاهی واقع شده است. نوآوری این پژوهش ترکیب هم‌زمان 12 شاخص محیطی و هیدرولوژیکی در چارچوب AHP-GIS و تمرکز بر شرایط اقلیم خشک کاشان بود. یافته‌های این پژوهش می‌تواند مبنای مناسبی برای برنامه‌ریزی مدیریت بحران و اجرای اقدامات پیشگیرانه در سطح شهرستان کاشان باشد.

چکیده English

Flooding is one of the most significant natural disasters that has extensive impacts on various regions of Iran, particularly in Kashan County. Each year, this phenomenon causes considerable financial damage to local infrastructure and often results in human casualties. Given the importance of this issue, identifying and assessing flood-prone areas can play a crucial role in minimizing losses and preventing the destructive effects of floods. Accordingly, the present study focuses on flood susceptibility zoning in Kashan County, located in central Iran. In this research, Geographic Information System was employed as an effective analytical tool. In the first stage, raster maps related to key indicators influencing flood susceptibility were prepared. These indicators included environmental and geographical variables affecting flood occurrence. Subsequently, the maps were analyzed using the Analytical Hierarchy Process, one of the most widely used multi-criteria decision-making methods for weighting. The weights of each criterion and their respective classes were determined through this process. Finally, the flood susceptibility map was generated using the raster calculator tool within the GIS environment. The results indicate that approximately 30% of the county’s area falls within zones of high flood risk, primarily covering the eastern regions characterized by high population density and urban development. In contrast, about 60% of the area lies within low-risk zones, mostly located in the western parts of the county with gentle slopes and dense vegetation cover. The novelty of this study lies in the simultaneous integration of twelve environmental and hydrological indicators within the AHP-GIS framework, with a specific focus on the arid climatic conditions of Kashan. The findings of this research can serve as a valuable basis for disaster management planning and the implementation of preventive measures across Kashan County.
