Experimental and Numerical Investigations of a River Embankment Model under Transient Seepage Conditions

The evaluation of riverbank stability often represents an underrated problem in engineering practice, but is also a topical geotechnical research issue. In fact, it certainly true that soil water content and pore pressure distributions the materials vary with time, due to changeable effects hydrometric climatic boundary conditions, strongly influencing bank conditions. Nonetheless, assessment hydraulic mechanical behavior embankments are currently performed under simplified hypothesis steady-state seepage, generally neglecting unsaturated related issues. this paper, comprehensive procedure for properly defining key aspects presented and, particular, characterization partially saturated conditions suitably compacted mixture sand finer material, typical flood main river Po tributaries (Italy), reported. laboratory results have then been considered modelling embankment performance transient seepage following set possible peaks. outcome present contribution may provide meaningful insights, practitioners researchers, risk embankments.
