The graph plots shear modulus in megapascals against depth in metres. Depth ranges from 0 to 14 metres and shear modulus ranges from 0 to 150 megapascals. Diamond markers for 25 grams increase from about 60 megapascals at 1.4 metres to about 82 megapascals at 2.3 metres. Triangle markers for 50 grams increase from about 70 megapascals at 2.6 metres to about 100 megapascals at 4.5 metres. Circle markers for 75 grams increase from about 84 megapascals at 4 metres to about 109 megapascals at 6.7 metres. Square markers for 100 grams increase from about 82 megapascals at 5.7 metres to about 130 megapascals at 9.7 metres. Open triangle markers from Almeida et al. 2024 and open circle markers from Almeida et al. 2023 show values near 54 to 97 megapascals between 5.8 and 11.7 metres. Curves from Hardin and Drnevich 1972, Seed and Idriss 1970, and Oztoprak and Bolton 2013 increase gradually with depth from near 0 megapascals at the surface to about 114, 148, and 136 megapascals at 14 metres.Small-strain shear modulus profile of São Francisco sand at Dr = 80%
