بررسی شبکه آب رسانی و نظام توزیع آب در دوره اسلامی(مطالعه موردی شهر سنقر)

درجستار پیش رو به روش پژوهش تحلیلی – توصیفی نحوه شکل گیری شبکه آب رسانی و نظام توزیع آب در شهر سنقر از دوره های میانی تا معاصر اسلامی مورد بررسی قرار گرفته است و اطلاعات کتابخانه ای در قالب اطلاعات اسنادی و آرشیوی ویافته های میدانی به شیوه غیر تماسی em گردآوری شده است. هدف از این بررسی شناخت هر چه بهتر شبکه آب رسانی سنتی شهر سنقر است که درگذشته نیاز جمعیت این شهر را رفع می نمود و اینک به دلیل عدم آگاهی از وضعیت فعلی نظام سنتی آب، و گسترش سازمان فضایی و فیزیکی شهر و ایجاد خطوط لوله کشی آب و فاضلاب، آثار باستانی وابسته به آب در زیر بافت نوین شهر مدفون شده است و شناسایی هر چه بهتر و مستندنگاری یافته ها در این زمینه اهمیت به سزایی در شناخت هویت فرهنگی و تاریخ فراموش شده شهر سنقردارد. لذا به دنبال پاسخ به این پرسش که شبکه آب رسانی نظام سنتی آب چه تاثیراتی بر شهر از گذشته تاکنون داشته است.؟ این فرضیه در نظر گرفته شد که به نظر می رسد شبکه آب رسانی و توزیع آب در شهر سنقر درشکل گیری و انسجام محله ها ازدوره میانی اسلامی به بعد تاثیرداشته است. دیوان حاکم در شهر سنقر از دوره میانی تا معاصر اسلامی برحفظ آثار مرتبط با آب و نحوه چگونگی توزیع آب در محله ها نظارت داشته است. نتیجه اینکه محله ها با توجه به اسناد و شواهد باستان شناسی مطابق با نظامنامه تقسیم آب در بافت سنتی شکل گرفته است و شهر سنقر از دوره های میانی تا معاصر اسلامی بر پایه شبکه آب رسانی دارای نظام سنتی توزیع آب بوده است.

Investigation of water supply network and water distribution system in the Islamic period(Case study of Sonqor city)

IntroductionIn the present research, the traditional water system and the way of obtaining and exploiting water resources in the past have been studied. To verify the existence of this traditional system in this city, archival documents, which had a significant impact on our understanding of urban development and the water supply network, were referred to. It is the commencement of our understanding of how to use traditional canals and waterways, the signs of which can be recognized in the ancient context. Consequently, the key question was raised as follows: what effects did the water supply network and the traditional water system have on the formation of the spatial organization? In response to this question, this hypothesis was shaped that it seems that the water supply and water distribution network in the city of Sonqor affected the formation and cohesion of neighborhoods from the middle Islamic period onwards.Data and methodThe current research is applied research regarding the purpose of the research method, the data collection method is a case study, and the noncontact method of electromagnetism method has been subjected to a field survey. This method was used to determine the movement of water underground and to locate and prove the existence of springs and alluviums. The determined points of springs and canals as the studied community have been evaluated in a descriptive and nonexperimental format. Collecting information from library and field methods and in a nonexperimental descriptive format based on documents and ancient evidence, springs, aqueducts and reservoirs were located and identified on the maps using the analyticaldescriptive method.Discussion and conclusionAccording to soundings done on the identification points of the springs outside the city, which were checked within a radius of 2 km from the city, the slope of the water flow of the springs and canals along the canal, waterways and streams based on the roughness and height position in the depth of the ground or the ground surface was calculated and measured based on the height of a place above the sea level. The result was that on the eastern side of Danesh Sara and Shah Murad Kariz; on the north side of the Chaman Pashm kariz; and on the western side with Malik kariz and Dara Maleh valleys, the depth of the water flow in the ground is between 3 and 7 meters. Underground water flows from the north of the city to the south of the city, with the slope of the land between 1.5% and 2% of natural alluvium and the water of springs and canals to the lower parts of the city. On the east side of the city, water flows downstream from the Daneshsara aqueduct with a slope of 2%, in the center of the city with a slope of 1.68%, and on the west side of the city with a slope of 1.5%. This procedure can be proven in the vicinity of the northern aqueducts compared to the southern aqueducts and in comparison to the height above sea level. Out of the total number of springs and aqueducts in Sonqor city, 17 points were identified and investigated, out of which 6 points had ancient remnants, and the rest of the studied community were located in the urban context.ResultsFrom the geology and natural geography point of view and according to the field and noncontact EM investigations, the collected information designates that the city of Sonqor was built on alluvial layers. These alluvial layers have changed the earth’s surface water path over millions of years. This change has caused the alluviums in the northeast to be higher than the alluviums downstream in the south and southwest. Water appears at fewer than 5 meters on the alluvial layers and is easily accessible to the early inhabitants. Man can build his residence near natural springs by relying on communication and interaction with nature.Consequently, in response to the research question, it
