The document discusses engineering geology and provides examples of dam failures due to geological factors. It summarizes case studies of the St. Francis Dam in California and the Austin Dam that failed due to geological issues. It also discusses several dams in India like the Tigra Dam and Kedarnala Dam in Madhya Pradesh and the Nanak Sagar Dam that encountered problems. The document further covers topics like weathering processes and its impact on rock formations and structures.
