The Rankine lecture is an annual lecture organised by the British Geotechnical Association named after William John Macquorn Rankine, an early contributor to the theory of soil mechanics.
This should not be confused with the biennial BGA Géotechnique Lecture.
The Rankine Lecture is held in March each year. In even-numbered years, the lecturer is from the UK. In odd-numbered years, the lecturer is from outside the UK. Each lecture is usually published[1] in Géotechnique.[2]
