چکیده مقاله :
چکیده زمینه و هدف: توسعه شهرنشینی و افزایش سطوح نفوذناپذیر در بسیاری از موارد، منجر به افزایش حجم رواناب و ایجاد سیل در نواحی پایین دست شده است. یکی از روش های مفید در کاهش خطرات سیل در مناطق شهری، استحصال رواناب های شهری و استفاده از آن در مصارف غیر شرب می باشد. با توجه به توسعه شهرسازی در منطقه 22 تهران و افزایش خطر سیل، و همچنین ضرورت توسعه فضای سبز در این منطقه سعی گردیده، تا استحصال رواناب شهری به منظور تامین بخشی از آب مورد نیاز فضای سبز این منطقه صورت گیرد. این مطالعه با هدف برآورد نیاز آبی فضای سبز منطقه 22 در طول یکسال و برآورد حجم رواناب سالیانه منطقه و سپس استفاده بهینه از رواناب قابل استحصال جهت آبیاری فضای سبز می باشد. روش بررسی: به همین منظور ضمن شناسایی فضای سبز منطقه پرسشنامه هایی تهیه و با کمک متخصصین، نیاز آبی گونه های موجود در منطقه طی یکسال تخمین زده شد و سپس حجم رواناب یکساله حاصل از بارش ها محاسبه گردید. یافته‌ها: با توجه به محاسبات انجام شده نیاز آبی فضای سبز منطقه حدود 534/969/14 متر مکعب می باشد در حالیکه متوسط سالانه حجم رواناب حاصل از بارش ها حدود 441/285/33 متر مکعب تخمین زده شد. با توجه به نتایج بدست آمده چنانچه بتوان با مدیریت اصولی یک چهارم از این رواناب که حدود 360/321/8 متر مکعب است را کنترل و به مصرف آبیاری فضای سبز منطقه رسانید، می توان حدود 5/55 درصد از آب مورد نیاز این بخش، که در حال حاضر با صرف هزینه و از طریق تانکر تامین می گردد را جبران نمود. بحث و نتیجه‌گیری: با توجه به یافته های تحقیق و شرایط موجود، روش هایی از جمله سد خاکی، پشته های هلالی و لوزی شکل در جاهایی مثل پارک های جنگلی چیتگر، وردآورد، لتمال و خرگوش دره می تواند به عنوان الگوی مناسب استحصال آب در منطقه پیشنهاد گردد.
Background and Objective: Urbanization and increase in imperious surfaces, in many cases, have led to increase of runoff volumes and flooding in downstream areas. One of the useful methods for reduction of flood risk in urban areas is urban runoff harvesting to be used for non-potable purposes. In this study, according to urban development in region 22 of Tehran and increased risk of flooding, as well as the need for green spaces development, it was attempted to implement urban runoff harvesting to supply a part of water required the green spaces in this area. Method: For this purpose, green spaces of region 22 were identified and then water requirements of different species in one year was estimated using a questionnaire filled by specialists. The annual runoff volume was also calculated. Findings: Result of the calculations showed that water requirement of green spaces is 14,969,534 cubic meters while the average annual runoff volume was estimated as 33,285,441 cubic meters. According to the results, if only a quarter of the runoff (8,321,360 cubic meters) is controlled by special management, it would be possible to provide 5,55% of the water required for irrigation of green spaces, which is currently supplied by tankers and is costly. Discussion and Conclusion: Finally, some methods such as earth dams, Crescent- shaped stacks and diamond-shaped stacks were suggested as a good models for water harvesting in places such as Cheetgar Forest Park, Vardavard, Letman and Khargooshdare.
