توضیحات
This work is designed to broaden the scope with which many people regard a river. Rivers are commonly regarded from a very simplistic perspective as conduits for downstream flows of water. In this context, it may be considered acceptable and necessary to engineer the channel to either facilitate such flows (e.g., channelization, levees) or limit flows and store water (e.g., water supply reservoirs, flood control). The book presents the concept of a river as a spatially and temporally complex ecosystem that is likely to be disrupted in unexpected and damaging ways by direct river engineering and by human activities throughout a drainage basin. Viewing a river as a complex ecosystem with nonlinear responses to human activities will help to promote a more nuanced and effective approach to managing river ecosystems and to sustaining the water resources that derive from rivers. In this context, water resources refers to ecosystem services including water supply, water quality, flood control, erosion control, and riverine biota (e.g., freshwater fisheries). Chapters in this book draw extensively on existing literature but integrate this literature from a fresh perspective. General principles are expanded upon and illustrated with photographs, line drawings, tables, and brief, site-specific case studies from rivers around the world. Read more…

این اثر برای گسترش دامنه ای که بسیاری از مردم با آن به یک رودخانه نگاه می کنند، طراحی شده است. رودخانه ها معمولاً از منظری بسیار ساده به عنوان مجرای جریان های پایین دست آب در نظر گرفته می شوند. در این زمینه، ممکن است مهندسی کانال برای تسهیل چنین جریانها (مثلاً کانالسازی، سیلابها) یا محدود کردن جریانها و ذخیره آب (مثلاً مخازن تأمین آب، کنترل سیل) قابل قبول و ضروری در نظر گرفته شود. این کتاب مفهوم رودخانه را به عنوان یک اکوسیستم پیچیده مکانی و زمانی ارائه میکند که احتمالاً به روشهای غیرمنتظره و مخربی توسط مهندسی مستقیم رودخانه و فعالیتهای انسانی در سراسر حوضه زهکشی مختل میشود. مشاهده رودخانه بهعنوان یک اکوسیستم پیچیده با پاسخهای غیرخطی به فعالیتهای انسانی به ترویج رویکردی دقیقتر و مؤثرتر برای مدیریت اکوسیستمهای رودخانه و حفظ منابع آبی که از رودخانهها سرچشمه میگیرد کمک میکند. در این زمینه، منابع آب به خدمات اکوسیستمی از جمله تامین آب، کیفیت آب، کنترل سیل، کنترل فرسایش و زیستهای رودخانه (به عنوان مثال، شیلات آب شیرین) اشاره دارد. فصلهای این کتاب بهطور گستردهای از ادبیات موجود استفاده میکنند، اما این ادبیات را از منظری تازه ادغام میکنند. اصول کلی با عکسها، نقشههای خطی، جداول، و مطالعات موردی مختصر و مختصر از رودخانههای سراسر جهان گسترش یافته و نشان داده شده است. بیشتر بخوانید…
