The present paper deals with a weakly nonlinear stability problem under an imposed time-periodic thermal modulation. The temperature has two parts: a constant part and an externally imposed time-dependent part. We focus on stationary convection using

Due to the disturbed rock mass and topographic conditions caused by earthworks, slopes are highly susceptible to weathering. During and just after the earthworks of a slope, the exposed rock material and mass may be subject to weathering and erosion.
