About

Zahra Kohankar Kouchesfehani is a civil infrastructure researcher specializing in trenchless technology renewal methods for aging stormwater and culvert systems. Her work focuses on evaluating the structural performance of polymeric spray-applied pipe lining (SAPL), an innovative, cost-effective technique that can renew complex geometries without excavation. In her most-cited study, she investigated the load-carrying capacity of circular and pipe arch culverts renewed with elastomeric polyurea SAPL, demonstrating how this method can structurally restore gravity conduits while accommodating intricate shapes through robotic application. Though early in her career, her research addresses a critical gap in sustainable infrastructure management—providing municipalities with data-driven solutions for extending the service life of deteriorating underground assets. Her contributions are particularly relevant as aging water systems worldwide require efficient, minimally disruptive renewal strategies. With growing interest in trenchless technologies, her work is poised to influence both academic research and practical engineering standards for culvert rehabilitation.
