[[Sarada K. Sarma|Sarma]] worked in the area of seismic analysis of earth dams under [[Nicolas Ambraseys|Ambraseys]] at [[Imperial College]] for his doctoral studies in the mid 1960s.<ref>Sarma S. K. (1968) ''Response characteristics and stability of earth dams during strong earthquakes''. PhD Thesis, Imperial College of Science & Technology, University of London</ref> The methods for seismic analysis of dams available at that time were based on the [[Slope stability analysis#Limit equilibrium analysis|Limit Equilibrium]] approach and were restricted to planar or circular failures surfaces adopting several assumptions regarding force and moment equilibrium (usually satisfying one of the two) and about the magnitude of the forces (such as interslice forces being equal to zero).
Sarma looked into the various available methods of analysis and developed a new method for analysis in seismic conditions and calculating the permanent displacements due to strong shaking. His method was published in the 1970s (the very first publication was in 1973<ref>{{Cite journal | last1 = Sarma | first1 = S.
