Spatial and temporal analysis of lake sedimentation under reforestation

Spatial and Temporal Analysis of Dusty Days in Iran

Iran is one of the world's arid regions and exposed to dust particles in the air. This is important in spatial and temporal terms as well as the affects human health. In this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. In the spatial and temporal analysis of dusty days 38 synoptic stations were studied. In order to conduct data...

  عدم قطعیت در بارش پیش بینی شده، یک منبع اصلی عدم قطعیت در پیش بینی بهنگام سیل می باشد. عدم قطعیت بارش از عدم قطعیت در مقدار بارش، توزیع زمانی و توزیع مکانی بارش تشکیل می شود. در این تحقیق به منظور پخش عدم قطعیت بارش در مدل پیش بینی سیل HEC-1 ، روش گسسته سازی زمانی در چهارچوب اصل بسط تئوری فازی و در ترکیب با الگوریتم ژنتیک نرمال بکار برده می شود. عدم قطعیت به علت توزیع زمانی ناشناخته بارش با ت...
