Overview

The Bawanur Dam is a hydroelectric infrastructure project currently under construction in the Kurdistan Region of Iraq. Located on the Sirwa River, the structure is situated just upstream of the town of Bawanur within the Sulaymaniyah Governorate. The dam is designed as an earth-fill structure, a common engineering approach for run-of-the-river hydroelectric schemes in the region. This project represents a strategic investment in the local energy grid and water resource management for the governorate.

The facility is engineered to support a 32 MW run-of-the-river hydroelectric power station. The dam itself stands 23 m tall, a height optimized to create the necessary hydraulic head for power generation while maintaining the flow characteristics of the Sirwa River. The operational status of the project is currently listed as under construction, with Hidroconstrucția identified as the operator. The use of an earth-fill design allows for flexibility in construction using local materials, which is typical for dams of this scale in the Kurdish highlands.

Project Objectives

The Bawanur Dam serves three primary functional objectives: power generation, flood control, and irrigation. The 32 MW capacity of the run-of-the-river power station contributes to the electrical supply of the Sulaymaniyah Governorate, helping to stabilize the regional grid. Run-of-the-river systems are particularly effective in this context as they rely on the natural flow of the river, minimizing the need for massive reservoir storage while still capturing significant kinetic energy from the water.

In addition to energy production, the dam plays a critical role in flood control. The Sirwa River, like many waterways in the Kurdistan Region, experiences seasonal variations in flow. The 23 m high earth-fill structure helps regulate these fluctuations, reducing the risk of downstream flooding in the town of Bawanur and surrounding agricultural lands. This flood mitigation capability is essential for protecting infrastructure and residential areas during peak flow periods.

The third key objective is the provision of irrigation water. The dam’s ability to manage water flow ensures a more consistent supply for agricultural activities in the region. This supports local farming communities by providing reliable access to water for crops, thereby enhancing food security and economic stability in the Sulaymaniyah Governorate. The integration of power generation, flood control, and irrigation makes the Bawanur Dam a multifaceted infrastructure asset for the area.

Engineering Design and Specifications

The Bawanur Dam is engineered as an earth-fill structure, a design choice that leverages locally available materials to create a robust barrier across the Sirwa River. This construction method involves the compaction of soil, sand, and gravel to form a stable embankment capable of withstanding the hydrostatic pressure of the reservoir. The dam rises to a height of 23 m, a dimension carefully calculated to optimize water retention while minimizing the volume of fill material required for the project in the Sulaymaniyah Governorate of the Kurdistan Region of Iraq. The earth-fill configuration is particularly suited to the geological conditions upstream of the town of Bawanur, providing a cost-effective and durable solution for the region's hydroelectric infrastructure needs.

Hydroelectric Power Station Configuration

Integrated with the dam is a run-of-the-river hydroelectric power station, designed to generate 32 MW of electrical capacity. This configuration relies primarily on the natural flow and elevation drop of the Sirwa River rather than storing vast quantities of water behind the dam wall, although the reservoir provides necessary head and regulation. The 32 MW output is intended to contribute significantly to the local energy grid, offering a renewable source of power that complements other energy infrastructure in the Kurdistan Region. The run-of-the-river design minimizes the environmental footprint compared to large reservoir schemes, allowing for a more continuous flow of water downstream while capturing kinetic energy for turbine generation.

Reservoir Functionality: Irrigation and Flood Control

Beyond power generation, the Bawanur Dam serves critical multi-purpose functions for the surrounding agricultural and urban areas. The reservoir created by the 23 m high earth-fill structure plays a vital role in flood control, mitigating the impact of seasonal high flows on the Sirwa River that historically affected the town of Bawanur and downstream communities. By regulating the river's discharge, the dam reduces the risk of flooding during peak rainfall periods, protecting infrastructure and agricultural land. Additionally, the stored water is utilized for irrigation, supporting agricultural productivity in the Sulaymaniyah Governorate. This dual-purpose design enhances the economic viability of the project, ensuring that the 32 MW hydroelectric facility also delivers tangible benefits in water resource management for the local population.
