  • A macroscopic one‐dimensional analytical model has been developed for the attenuation of low‐frequency pressure waves in the water of a variably saturated porous medium. The developed model associates pressure amplitude attenuation with pore scales. Pressure propagation in a single pore size is described by a linear wave equation, and the composition of characteristic pore sizes are combined for representing the porous medium. The capillary bundle approach allows for a geometrical abstraction of the pore sizes and the definition of the water‐filled capillaries under different water content states. This approach allows the pore water pressure attenuation to be addressed directly with r...
