Once the pipeline touches the seabed , flow mechanism changes and local scour
ceases due to the significant reduction of shear stress underneath the pipeline .
Fig . 6 gives the maximum scour depth relative to sagging 60 40 20 0 - 20 .

( 1997 ) applied the three - phase model to estimate phase hold - ups in three
phase stratified flow . They estimate the phase hold - ups by comparing the
pressure drops in each phase which are derived from the phasic momentum
