Ecological Restoration of Wadi Al-Teen

University of Baghdad, College of Engineering

Project idea

The project originates from a critical reading of Wadi Al-Teen as a destabilized landscape—ecologically degraded, hydrologically disrupted, and socially fragmented under the pressures of desertification and infrastructural expansion. These transformations have displaced local fishermen and farmers who once sustained the valley’s rural economy. Rather than introducing architecture as an isolated intervention, the proposal establishes a landscape-driven regenerative system in which environmental intelligence directly informs spatial formation.
The valley is redefined as a self-sustaining ecological framework structured around water retention, biodiversity recovery, and socio-economic reactivation. At its core, a sequence of cascading terraced lakes decelerates flash-flood runoff, extends water retention cycles, and facilitates deep aquifer recharge, transforming episodic water events into a continuous regenerative process.
This system is supported by a lightweight architectural strategy embedded within non-sensitive, previously degraded zones to preserve ecological integrity. The project’s formal language emerges from the natural topographic contours, ensuring all interventions are precisely calibrated to the site’s environmental logic. Rather than imposing a dominant object, the proposal adopts a reversible and adaptive approach, where architecture operates as an enabling layer and the landscape becomes the primary agent of long-term transformation.

Project description

The project is conceived as a multi-layered ecological and spatial system for the restoration and activation of a desert valley, integrating hydrological infrastructure, environmental conditioning, and human occupation into a resilient design strategy.
Spatial organization follows the natural topography, with water flow as the primary ordering principle. Four interdependent terraced lakes are embedded along contour lines to maximize retention and infiltration, forming a continuous ecological corridor with a progressive programmatic gradient:
The Community Lake activates a civic and economic threshold, re-engaging local vendors and river-based economies.
The Ecological Restoration Lake functions as a core for biodiversity repair and habitat renewal.
The Contemplative Lake creates a condition of stillness and sensory immersion.
The Recreational Lake extends into a low-impact eco-touristic and preservation interface.

Technical information

The technical strategy integrates hydrological engineering, passive environmental control, and lightweight structural systems into a cohesive high-performance framework.
The terraced lake system operates as a cascade-based infrastructure, where each level acts as a retention basin that slows runoff, promotes infiltration, reduces erosion, mitigates flooding, and enables long-term groundwater recharge.
This is complemented by a reengineered subsurface water distribution network derived from the Qanat system. This gravity-fed underground infrastructure transports water efficiently while eliminating exposure to heat and evaporation. By utilizing the thermal stability of the subterranean substrate, it enhances efficiency, durability, and resilience in extreme climates.
A decentralized network of permeable micro check dams, constructed from local stone, regulates water velocity, facilitates sediment deposition, improves soil fertility, and stabilizes slopes, accelerating the formation of productive soil strata.
A large tensile canopy functions as a key bioclimatic device. Reinterpreting the traditional Arabic tent, it operates as a thermodynamic filter that reduces solar radiation, lowers ambient temperatures, and creates shaded environments. It enhances human comfort, protects vegetation, enables tree growth, and significantly reduces evaporation from the lakes, making it central to both microclimate regulation and water conservation. Rainwater harvesting is fully integrated through canopy and building surfaces. Tensile structures channel water toward structural masts into underground storage or back into the lake system, while building roofs act as secondary collection surfaces within a closed-loop hydrological cycle.
Architectural elements follow a lightweight tectonic strategy using steel–timber hybrid systems, minimal point foundations, and elevated platforms. This minimizes ground impact, preserves ecological continuity, and ensures full reversibility while maintaining the landscape as the dominant system.
