صحت‌سنجی پهنه و هیدروگراف سیلاب با استفاده از داده‌های بارش ERA5 (مطالعه موردی: حوضه زشک) [PDF]

جغرافیا و مخاطرات محیطی, 2022
بارش یکی از اصلی‌ترین عوامل وقوع سیلاب‌هاست که به علت عدم پراکندگی مناسب ایستگاه‌های باران‌سنجی و تازه‌تأسیس‌بودن برخی از این ایستگاه‌ها در اکثر حوضه‌های کشور، استفاده از داده‌های بارش با چالشی جدی روبروست. ازاین‌رو روش‌های دورسنجی می‌توانند یکی از گزینه‌
