Abstract              The case of a partially lined
                      trapezoidal channel excavated
                      in a highly permeable soil of
                      infinite depth is investigated in
                      this paper. The results of an
                      earlier research are Modified
                      and used in establishing
                      equations     for     estimating
                      channel length downstream
                      from a reference section and
                      channel discharge at a general
                      section. The above mentioned
                      equations are provided for
                      channels with side lining as well
                      as for those with bottom lining.
                      The solution of a numerical
                      example shows that equations
                      are simple and practical.
                      Inspection of a number of
graphs illustrates the effect of
various parameters on the
channel length. Distribution of
discharge along with channel
the lining efficiency for both
bottom lined and side lined
channels.
