چکیده

چکیده رود شط‌العرب حدوداً به طول 200 کیلومتر است و از به هم پیوستن دو رود دجله و فرات در شهر قرنه که در 74 کیلومتری شمال غربی شهر بندری بصره در جنوب عراق واقع شده است، شکل می‌گیرد. این رود تحت تأثیر تغییرات اقلیمی، باران‌های مکرر و مستعد خطر و ریسک طغیان رود و همچنین جاری شدن سیل است. حوضه رودخانه شط‌العرب در محدوده شهرستان بصره شاهد وقوع سیلاب‌ها و نتایج مخرب آن بوده است. هدف از این پژوهش ارزیابی و تحلیل مکانی خطر طغیان رود شط‌العرب در محدوده شهرستان بصره عراق با بهره‌گیری از سیستم اطلاعات مکانی (GIS) می‌باشد. در این پژوهش از GIS برای برآورد و ارزیابی مکانی و پهنه‌بندی مناطق طغیان رود شط‌العرب در منطقه بصره با بهره از داده‌های موجود استفاده خواهد شد. با مشخص نمودن انواع کاربری‌های اطراف رودخانه، تحلیل دقیقی از نحوه توزیع آن‌ها در مناطق با خطرپذیری مختلف ارائه می‌کند. نتایج نشان می‌دهد که کاربری‌ زمین‌های کشاورزی با توجه به مساحت زیادی که دارند بیش از سایر کاربری‌ها در معرض خطر طغیان قرار دارد. نتایج این تحقیق می‌تواند تأثیر زیادی در پیشگیری از ایجاد صدمات جبران‌ناپذیر طغیان در این محدوده داشته باشد.

چکیده [English]

Abstract The Shatta al-Arab River is approximately 200 km long and is formed by the confluence of the Tigris and Euphrates rivers in the city of al-Qarna, 74 km northwest of the port city of Basra in southern Iraq. The river is affected by climate change and frequent rains, it shows the risk of flooding and overflowing at the riverside. The Shatta al-Arab River Basin in the city of Basra has been faced with floods and devastating consequences. The purpose of this study is to evaluate and analyze the spatial risk of river overflow of the Shatta al-Arab River in the city of Basra, Iraq, using the Geospatial Information System (GIS). GIS was used to estimate and evaluate the location and zoning of the Shatt al-Arab floodplain in Basra using the available data. By identifying the types of land uses around the river, provided a detailed analysis of how they are distributed in different risk areas. The results show that the agricultural landuse due to its large area is more at risk than other uses. The results of this study can have a significant impact on preventing irreparable flood damage in this area.
