distribution of unit discharge, determined from measurements made at six cross
sections using a temporary cable and boat, is compared to the lateral distribution of
unit discharge computed by the model. The largest errors, as one would expect,
occur at the upstream end of the study reach in the vicinity of cross section 5. This
result occurs because the lateral distribution of flow entering the study reach has
been assumed to be uniform, althou~h this assumption is only an approximation.
In some instances, where the unit discharge is increasing or decreasing rapidly in
the cross stream direction, there appears to be discrepancies between the measured
and computed values. These apparent discrepancies OCCur because the model results
