Gaston Sauvage de Saint Marc entered in 1938 Ecole Centrale in Paris but was mobilized one year later and wounded in 1940 such that he graduated as a hydraulic engineer in 1943. He then joined the pump designer Neyret-Belier in Grenoble where he took responsibility for the well-known in-house hydraulic laboratory. In the 1950s, this institution was transformed into NEYRPIC's Laboratoire Dauphinois de l'Hydraulique.

Sauvage's first project related to groundwater flow across earth dams. By application of the Laplace equation thereby assuming the validity of the Darcy law for porous media, the flow below a water tightness sheet was determined with a graphical approach in 1947. In collaboration with Julien Kravtchenko (1911-1994) and Mladen Boreli (1922-1995), Sauvage presented boundary singularities arising in plane groundwater flow. The method was applied for a point common to a free surface and an impermeable wall. The result was compared with the classical solutions of Morris Muskat (1907-1998) and Pelageya Yakovlevna Kochina (1899-1999). In the mid 1950s, Sauvage turned his attention more to problems of hydraulic engineering and thus considered in the 1959 paper free water jets downstream of gates. In 1960 then, he investigated with Maurice Bouvard (1923-) the elastic equilibrium of an internally pressurized conduit of variable wall thickness. Results were then extended to tunnels driven in rock by assuming that the latter behave as a completely porous medium.
