Abstract
إن الوقاية من المخاطر الكبرى وتسيير الكوارث اصبحت تشكل نظاما شاملا، تقوم الدولة بوضعه وتسييره وتتولى المؤسسات العمومية والجماعات الإقليمية انجازه في إطار اختصاص كل منها، بالتشاور مع المتعاملين الاقتصاديين والاجتماعيين والباحثين والتقنيين، وبتطور التجمعات العمرانية وازدهار الصناعات، إلى جانب ظهور مفاهيم جديدة كالتنميـة في مجالات شتى بما في ذلك مجال العمران ، والذي اثر نوعا ما على الطبيعة مما أدى الى حدوث كوارث متكررة والتي تحدث اضرار جسيمة للإنسان وممتلكاته، وهذا ما جعل التفكير الإنساني يتطور في ميدان الحماية من آثار الكوارث الطبيعيـة سيما الفيضانات بقصـد المحافظة على العنصر البشري والاقتصادي، وعلى غرار دول العالم تسعى الجزائر الى الحد من أضرار الأخطار الكبرى من خلال الإجراءات المتخذة في هذا الشأن من خلال تبني الحكومة الجزائرية لمخطط وطني للوقاية مـن الكـوارث وتنظيم التدخلات والإسعافات، إضافة إلى مختلف أنواع أدوات التعمير، وقد قمنا بدراسة خطر الفيضانات على مدينة المسيلة وبالتحديد بمنطقة التوسع العمراني والتي تم بها تحليل المعطيات والبيانات المناخية والطبوغرافية والعمرانية وذلك بالاعتماد على نظم المعلومات الجغرافي ،SIGوتم تحديد المناطق الخطرة داخل المجال المبني وتصنيف مخططات شغل الأرض حسب درجة الخطورة، حيث خلصنا في نهاية البحث الى أن توسع مدينة المسيلة لم يأخذ فيه بعين الاعتبار خطر الفيضانات في تجسيد أدوات التهيئة والتعمير
Prevention of major risks and the management of disasters constitute a comprehensive system, developed and managed by the State and carried out by public institutions and regional groups within their respective jurisdictions, in consultation with economic, social, researcher and technical clients, the development of urban communities and the prosperity of industries, as well as the emergence of new concepts such as development in various areas, including urbanization, which has affected nature, resulting in frequent natural disasters that cause damage to human beings and property. This is why human thinking has evolved in the field of protection against the effects of natural disasters (floods) in order to preserve the human and economic component, and like the countries of the world, Algeria seeks to reduce the damage of major threats through actions taken in this regard through the adoption of a national disaster prevention scheme by the Algerian Government and the organization of interventions and aid, in addition to various types of urban means, The study of hazards in the city focused on the risk of flooding, specifically in the expansion area, where the analyze of climatic, topographic and urban data were based on SIG, the hazardous areas within the built area were identified and classification the land occupation plans were by the degree of risk. At the end of the research w here we concluded that the expansion of the city of M’sila did not take into account the major dangers in the embodiment of the tools of preparation and reconstruction.
