Iran (IMNA) - Long before urban planning emerged as a formal discipline, generations of engineers, water managers and local communities developed systems that enabled Isfahan to flourish in an environment where water was never abundant.
Today, as cities worldwide grapple with drought, population growth, rising temperatures and increasingly unpredictable rainfall, these traditional approaches are attracting renewed interest. Isfahan's experience offers a valuable starting point for a broader discussion: Could the water management systems of historic cities provide lessons for building more resilient urban environments?
A city shaped by the flow of water
The historical relationship between Isfahan and water is deeply embedded in the city's urban development. During the Safavid era, when Isfahan emerged as a major political and cultural centre, water was not simply regarded as a natural resource. It was an essential element of urban planning and a defining factor in the city's growth.
The Zayandeh Rud River formed the backbone of this relationship. Flowing through central Iran, it sustained agriculture, residential areas, green spaces and everyday urban life. As Isfahan expanded, however, distributing water across the city required more than access to the river. It called for an organised network capable of delivering water to different neighbourhoods for a variety of purposes.
One of the most distinctive features of this network was the system of engineered waterways known as Madi. These open channels diverted water from the Zayandeh Rud and carried it into different parts of the city, contributing to Isfahan's distinctive urban landscape.
Historical research on Safavid Isfahan indicates that this network operated within an established framework of water allocation, regulations and administrative responsibilities. Water distribution was governed by specific rules, while officials known as Mirabs supervised and managed the process.
A 2017 study by Safa Mahmoudian and Mehrdad Qayyoomi Bidhendi examined both the physical structure of the Madi network and the social and administrative arrangements that sustained it.
Isfahan's historic water infrastructure was therefore far more than a collection of canals. It represented an integrated urban system in which engineering, public administration, local knowledge and collective agreements worked together.
The forgotten intelligence beneath the ground
While the Madi network channelled water through Isfahan, another traditional system played an equally important role in sustaining settlements across the region: the Qanat.
Unlike open waterways, Qanats transported groundwater through gently sloping underground tunnels. Vertical shafts provided access for construction, ventilation and maintenance, allowing water to flow from aquifers to villages, towns and agricultural land without requiring continuous mechanical pumping.
This technology was particularly valuable in semi-arid regions, where surface water was often scarce or unreliable. Constructing a Qanat demanded considerable technical expertise, financial resources and cooperation. Its long-term operation also depended on regular maintenance and the shared responsibilities of the communities that relied on it.
In 2023, Fabian Sarga published research examining a Qanat in northwestern Isfahan, near Varkān, in an area known as Mobārrak Ābād. The study explored how the system supplied water to agricultural land, gardens and village buildings, illustrating the close relationship between water infrastructure, settlement patterns, economic activity and everyday life.
The significance of these systems extends well beyond their engineering achievements. They demonstrate how communities developed long-term arrangements for managing limited resources and distributing responsibilities among different users.
At a time when groundwater depletion is becoming an increasingly serious challenge in many parts of the world, the history of Qanats raises an important question: What can contemporary cities learn from traditional water systems that worked in harmony with local environmental conditions?
When water infrastructure becomes part of a city's identity
In Isfahan, water has also played a defining role in shaping architecture and public spaces. The city's historic gardens, pools, fountains, bridges and tree-lined avenues were not merely decorative features. They formed part of a broader relationship between water, climate and everyday urban life.
Water helped organise and shape public spaces, while vegetation and shade created comfortable environments where residents could gather, socialise and enjoy outdoor activities.
The historic water channels also contributed to the distinctive character of Isfahan's neighbourhoods. By connecting different parts of the city, they established a relationship between essential infrastructure and everyday public life, an aspect that is not always adequately addressed in contemporary urban planning.
This heritage has become increasingly relevant to discussions about urban landscapes and conservation. A 2023 study examining Isfahan's historic waterways applied the Historic Urban Landscape (HUL) approach to propose protective zones around these systems, recognising their central, functional and visual significance.
The findings highlight an important principle: protecting historic waterways requires more than preserving individual structures. Their relationship with the wider urban environment, including surrounding buildings, landscapes and public spaces, must also be considered.

From heritage conservation to climate resilience
Renewed interest in traditional water systems does not mean that historic infrastructure can simply replace modern water networks. Qanats, for example, depend on groundwater availability and require specialised knowledge and regular maintenance. Their capacity is also limited by the volume of water stored in the aquifers that supply them.
In areas where groundwater levels are declining rapidly, restoring a Qanat without addressing the underlying water crisis is unlikely to provide a lasting solution.
Research into Qanat systems in central Iran has examined their hydrological, social and economic sustainability, highlighting the importance of indigenous knowledge in maintaining and restoring these traditional networks.
For Isfahan, this means approaching water infrastructure as part of a comprehensive urban and environmental strategy rather than treating it as an isolated heritage conservation project. Protecting historic waterways, documenting traditional distribution networks, preserving local knowledge and incorporating water-sensitive design into contemporary neighbourhoods could help reconnect urban development with the city's environmental heritage.
It also requires recognising that the Zayandeh Rud cannot be considered independently of its wider river basin. Water resources, agricultural demands, environmental requirements and urban consumption are closely interconnected. Sustainable solutions therefore depend on cooperation, integrated resource management and planning that extends beyond municipal boundaries.
The future may lie in looking back
For decades, urban development has often been associated with expanding infrastructure, extending networks and finding new ways to secure additional water supplies. Today, growing demand and mounting environmental pressures are encouraging cities to reconsider this approach.
Isfahan's history offers an important reminder that effective urban water management is not necessarily about bringing more water into a city. It is also about understanding where water comes from, how it moves through the urban environment, how it is shared and used, and how it can be protected for future generations.
The city's historic Madi channels, Qanats and water-related landscapes may belong to another era, but the principles behind them remain relevant. They demonstrate the value of integrating infrastructure with the natural environment, combining technical expertise with local knowledge and recognising water as a shared resource that requires collective responsibility.
For Isfahan, rediscovering this heritage could mean much more than restoring old canals or preserving historic gardens. It could provide an opportunity to rethink the relationship between the city, its river and the surrounding landscape.
As cities prepare for an increasingly water-stressed future, some of the most valuable solutions may already exist in knowledge developed and passed down through generations.
Perhaps the future of urban water management will not be built entirely on new ideas. Some of its most important foundations may already lie in the systems that earlier generations created.
