The IAEG Bangladesh National Group (IBNG) and the Nepal Society of Engineering Geology (NSEG), along with partner organizations in Bangladesh, Japan, and Nepal, are organizing the 15th IAEG Asian Regional Conference (ARC-15) in Kathmandu, Nepal, from November 27-29, 2025. This prestigious international conference series has been a crucial platform for advancing Engineering Geology in Asia. Over the years, geoscientists and engineers from around the world have contributed to and greatly benefited from the discussions at past IAEG Asian Regional Conferences. The upcoming event will be another key milestone in enhancing geoengineering knowledge and furthering the understanding of Engineering Geology in this region.

This will mark the third time Nepal is hosting an IAEG Asian Regional Conference, reaffirming its status as a favored destination for geoscientists and tourists alike. While ARC-15 was initially planned to be held in Dhaka, Bangladesh, the venue has now been shifted to Kathmandu, Nepal. The conference serves as a forum for geoscientists and engineers to engage in collegial discussions and share the latest research findings in the fields of Engineering Geology and related subjects. Both IBNG and NSEG have received an overwhelming response from the global geoscience community, and this event is poised to be another milestone in the history of ARC.

This first circular is being issued to provide important information about the conference. Pre-registration is now open through the official conference website (arc15.nseg.org.np). Geoscientists and engineers working in geoengineering, geotechnics, geology, disaster risk management and engineering geology are kindly encouraged to submit their pre-registration forms along with their details before the stated deadline. Your cooperation will greatly assist the organizers in planning and executing this significant event successfully.
