  EnvE/ESS 110, Hydrology and Climate  1 1.  Transient Unsaturated Flow  The degree of saturation is equal to moisture content divided by porosity,  water voids VV? ??'= = , therefore,  ? ??'= .  For flow in an elemental volume that may be only partially saturated, the equation of continuity  must reveal the time rate of change of moisture content as well as the time rate of change of water expansion  and aquifer compaction.  The  w ? ?  term in the continuity equation becomes  w ? ??'.  Applying the product  rule gives    () () () ()() ()()() wy wx wz ww wy wx wz w ww q qq xyzt t q qq x yz ttt ? ?? ?? ??? ? ??? ? ? ?? ?? ? ? ? ?? ??
