The presence of seepage of the flow from a channel or into it leads to a change in the bed deformation conditions and consequently the hydrodynamic characteristics of the channel. A study of the effect of seepage flows on the detachment of particles from the bed or incipient motion is of great interest, since this problem is related to the solution of important practical engineering problems. For instance, groundwater movement plays an exceptionally important role when constructing hydraulic structures, particularly dams; these problems are urgent when solving problems of the stability of dams and canal slopes. Seepage through boundaries of alluvial canals, rivers and streams is a common occurrence due to porosity of the granular material as well due to level difference between ground water and surface water in the canal. Seepage losses from alluvial canals have been estimated to range from 15 to 45% of total inflow (van der Leen et al., 1990). Clearly there is a continuing need to study or analyze seepage phenomena undergoing in the alluvial canals (Hotchkiss et al, 2001).  With the level of the free surface in a channel being different from the adjoining groundwater table, two typical seepage flows (bed suction and bed injection) may occur through the channel boundary (Rao and Sitaram, 1999; Yan et al., 2008). In the case of bed suction or downward seepage, water seeps out of the channel; while with bed injection or upward seepage, the channel receives additional water.
