12. Designing the shape of soil slopes stable during seepage fluctuations in California hillsides

: The ultimately stable slopes in the cases of seepage through the earth dam, under the sheet piling, and to the drainage trench are founded by the methods of linear differential equations, boundary-value problems, and hodograph of velocity.
