چکیده
مادی های اصفهان از رودخانه زاینده رود منشعب و به صورت شبکه ای منظم و شاخه ای در سطح شهر اصفهان گسترده شده تا علاوه بر کاربری های کشاورزی و آبیاری به آبادانی و زییایی محیط زیست کمک کند. در گذشته به منظور آبیاری زمین های کشاورزی از آنها استفاده می شد اما امروزه با تغییر کارکردشان هویت و کارایی گذشته خود را از دست داده اند. گسترش فعالیت ها و تغییرات اساسی در ساختار و عناصر شهری، باعث از بین رفتن اهمیت و هویت مادی ها در شهر اصفهان گردیده است. پژوهش حاضر با هدف شناسایی مشکلات مادی های مناطق 1 و 3 شهر اصفهان و راهکارهایی برای ساماندهی آنها صورت گرفته است. روش این پژوهش توصیفی- تحلیلی می باشد. در این راستا مشکلات موجود مادی های این دو منطقه با برداشت میدانی و با استفاده از دستگاه موقعیت یاب ماهواره ای شناسایی شد. سپس مشکلات برداشت شده دسته بندی و راهکارهایی در رابطه با رفع آنها ارائه شد. طبق مطالعات صورت گرفته طول شبکه مادی های منطقه یک 10921 متر (9/10 کیلومتر) و مادی چشمه نیاصرم با 3624 متر طویل ترین مادی این منطقه می باشد. در منطقه 3 نیز طول مادی ها 59/10921 متر (9/10 کیلومتر) و مادی چشمه نیاصرم با 72/3624 متر طویل ترین مادی این منطقه می باشد. نتایج نشان داد مادی های منطقه یک از 33 نوع مشکل برخوردارند که عمده ترین آنها اصلاح شیب بستر و نظافت می باشد. در منطقه سه نیز 18 مورد مشکل شناسایی شده که لایروبی و نظافت عمده ترین آنها می باشد. ساماندهی فضای سبز اطراف مادی ها و استفاده مناسب از مبلمان شهری و ایجاد فضایی به منظور بهره گیری و استفاده هرچه بیشتر ساکنان اطراف مادی ها از جمله مهمترین راهکارهای مدیریتی ساماندهی مادی ها در این دو منطقه است.Identification and Mitigation of Urban Madies Issues in Central Regions of Isfahan: Strategies for Their Effective Organization
The water streams branching from Zayandehroud in the city of Isfahan are called Madi and they are among the unique features of the structure of this city. In the past, they were used to irrigate agricultural lands, but today, with the change in their function, they have lost their past identity and efficiency. The expansion of activities and fundamental changes in the urban structure and elements have caused the loss of the importance and identity of Madi issues in the city of Isfahan. The current research has been carried out with the aim of identifying the Madi problems of Regions 1 and 3 of Isfahan and solutions to organize them. The method of this research is descriptive-analytical. In this regard, the existing Madi problems of these two areas were identified by field sampling and using a satellite positioning device. Then, the perceived problems were categorized and solutions related to their solution were presented. According to the conducted studies, the length of the Madi network of Region 1 is 10921 meters (10.9 km) and the Madi of Cheshme Niasserm is the longest Madi of this region with 3624 meters. In Region 3, the length of the Madi is 10,921.59 meters (10.9 km) and the Niaseram spring Madi is the longest one in this area with 3,624.72 meters. The results showed that Madies of Region 1 have 33 types of problems, the most important of which are bed slope correction and cleaning. In Region 3, 18 problems have been identified, of which dredging and cleaning are the main ones. Organizing the green space around the properties and using urban furniture and creating a space for the residents around the properties are among the most important management solutions for organizing the properties in these two regions.Keywords: Isfahan City, Madi, Regions 1 and 3 of Isfahan, Spatial Organization. IntroductionThe Madi system consists of artificial waterways and water transfer routes that transport water from the Zayanderud River throughout large parts of the urban fabric of Isfahan. Historically, the Zayanderud and its network of branched Madies played a crucial role in agriculture, water supply, surface water collection, and urban development. However, in addition to their benefits, Madies have also faced various challenges, resulting in their discontinuation and environmental concerns in certain regions. Identifying the issues facing Madies and developing solutions to address them can greatly improve the livability of Isfahan by enhancing its urban fabric, given the contextual, historical, and environmental significance of Madies. The present study examines the issues and disorders faced by Madies residing within Regions 1 and 3 of Isfahan. Materials and MethodsAn applied research approach was employed to achieve the study's objective, and a descriptive-analytical methodology was used to analyze the data. Data on the Madies' location, problematic areas, and the type and location of issues they encounter were collected through a field survey and a GPS device. To ensure the accuracy of the collected data, an expert provided their expertise and verified the information. The issues and challenges associated with each Madi were then identified and classified. Next, the collected data and information were entered into GIS software to visualize the locations of Madies and their respective problems on a map. Lastly, recommendations were put forth to manage the Madies in these two areas.Research FindingsMadies in Region 1 have a total of 33 problem types. Among these, the issue of ‘bed slope correction and cleaning’ emerges as a critical issue, with a prevalence of 18 instances in the area. The next most prevalent problem is related to ‘bed slope correction, dredging, and cleaning’, with 15 observed cases in the Madies area of this region. Furthermore, 23 of the problems in Madies within this area are related to ‘bed slope correction, cleaning, and dredging’. As noted earlier, although each of these three problem types is associated with another issue and viewed differently, they are still considered the primary problems in Madies, as they are also among the 23 problem types previously mentioned. Other problems encountered in the area include the need for green space organization and irrigation network management. In Region 3, there are a total of 15 problem types, with ‘dredging and cleaning’ emerging as the most prevalent issue, occurring 18 times. The second most prevalent issue involves ‘bed slope correction and cleaning’, with 11 instances. This region also experiences the problem of ‘dredging and cleaning’, along with 11 other issues, rendering it a significant issue. The research findings revealed that Madies in Region 1 encounter a greater number of issues than those in Region 3. Both regions encounter similar issues, including “bed slope correction and cleaning”, “organizing green spaces and bed slope correction”, “dredging and bed slope correction”, “dredging and cleaning”, and “dredging and organizing green spaces”. Region 1 exhibits a greater prevalence of all of the aforementioned issues, except for “dredging and cleaning”, which is more prevalent in Region 3. Discussion of Results and ConclusionMadies are a distinctive and remarkable feature of Isfahan's urban fabric, and undoubtedly, the Madies network is a crucial part of its identity. Running along a long path from the southwest to the northeast, Madies have given a unique shape to the city and are recognized as a significant element of its identity. Currently, however, the presence of issues in Madies has resulted in the neglect of these fundamental elements that once contributed significantly to the vibrancy of Region 3 of Isfahan which faces more problems than Madies in Region 1 due to having a higher number of Madies. Madies serve as vital life-giving elements that facilitate the connection and coherence of inner elements within neighborhoods. In areas where Madies exist, neighborhoods tend to have a more structured and organized layout, whereas those without them often exhibit a lack of cohesion among the elements within the neighborhood. Organizing and resolving the problems of Madies is essential for improving the structure of neighborhoods and enhancing the links between their elements. To achieve this, suitable solutions need to be devised for the issues affecting each Madi. The primary problem in Regions 1 and 3 is related to the need for ‘dredging and cleaning’. Therefore, it is imperative to undertake the dredging and cleaning of all Madies in these two regions and implement measures to ensure that the surrounding environment's health is maintained. For example, to prevent the growth and reproduction of insects and animals, Madies should be regularly dredged, and garbage must not be thrown into them. By organizing and utilizing the green space around Madies with appropriate urban furniture, the citizens can make the most out of this beautiful and serene area, which significantly contributes to the overall beauty and tranquility of the neighborhood and the city.
