MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511133068 A) filed by Central University Of Haryana, Mahendragarh, Haryana, on Dec. 29, 2025, for 'grooved pier for scour protection.'
Inventor(s) include Yudhveer Singh; Damodar Lal Meena; Dr. Vikas Garg; Shivam; Simran; Anil Kumar; Poonam; and Dr. D. V. S. Verma.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a cylindrical bridge pier (200) equipped with a plurality of circumferential grooves (204) formed along its outer surface for reducing local scour under flowing-water conditions. The grooves (204) are configured to disrupt near-bed flow (206), weaken formation of horseshoe vortices, and reduce sediment-erosion intensity at the pier foundation. The grooves extend fully around the pier circumference and are dimensioned relative to the pier diameter, including a groove depth (208) of 0.43D, a groove thickness (210) of 0.16D, and a groove spacing (212) of 0.24D. Alternative embodiments include uniform groove geometries optimized for site-specific hydraulic conditions, as well as retrofit configurations using prefabricated grooved jackets. Flume experiments demonstrate that the grooved pier achieves up to a 63% reduction in maximum scour depth compared to a plain circular pier under identical hydraulic conditions. The invention provides a simple, durable, and maintenance-free solution to enhance the stability and service life of bridges exposed to riverine and open-channel flows."
