In the rugged landscapes of Azerbaijan’s Karabakh region, where water is as precious as oil, a hidden geological battleground is quietly shaping the future of the country’s energy and water security. Movlud Teymurov, a researcher whose work bridges hydrology and geology, has uncovered how the very bedrock beneath our feet dictates whether rivers flow like steady veins or flash floods, a discovery with profound implications for industries from hydropower to agriculture.
Teymurov’s study, published in *Bulletin of Taras Shevchenko National University of Kyiv. Series Geology*, tracked river behavior across 25 years—a period of shifting climates and landscapes. His team found that rivers cutting through the Karabakh Plateau’s fractured volcanic rocks act like natural sponges, soaking up rainfall and releasing it slowly through underground channels. Here, baseflow—the groundwater contribution to rivers—often exceeds 50%, keeping water flowing even in dry months. “These rocks aren’t just passive layers; they’re active regulators of our most vital resource,” Teymurov notes. In contrast, rivers flowing over impermeable southern bedrock behave like storm drains, with 70–90% of their water racing away in surface runoff after rain.
The commercial stakes are clear. For energy producers, this means the difference between predictable hydropower output and erratic generation tied to unpredictable rainfall. Teymurov’s “natural regulation ratio” (NRR)—the balance between surface and subsurface flow—dropped by nearly 5% over 25 years due to land degradation and reduced vegetation. That decline isn’t just academic; it signals shrinking resilience against droughts, a growing threat as the region’s climate tightens its grip.
Industries relying on water—from thermal power plants to mining—will need to adapt. Rivers with high NRR, like those fed by volcanic aquifers, could support smaller, decentralized storage solutions, while others may demand costly reservoirs to stabilize supply. Teymurov’s work suggests that future water infrastructure planning must begin not with concrete, but with a drill core. “You can’t manage what you don’t understand,” he argues. “And in Karabakh, the bedrock holds the key.”
This isn’t just a story about rocks and rivers—it’s about energy security in a warming world. As Azerbaijan diversifies its economy beyond fossil fuels, the hidden geology of its waterways may determine which projects thrive and which falter. The research challenges engineers and policymakers to look deeper, literally, before building higher.
