From: Pore water pressure responses in silty sediment bed under random wave action

Wave and pore pressure Fourier spectra under different random waves: (a) wave spectrum in Test 2-1 and (b) pore pressure spectrum in Test 2-1 in 15 cm depth of bed; (c) wave spectrum in Test 2–2; and (d) pore pressure spectrum in Test 2–2 in 15 cm depth of bed.
