This research investigated how the canal effects biogeomorphological changes on the desert washes it blocks. The section of the canal traversing the study area was constructed between 1986 and 1987; aerial photographs and GIS were used to quantify landscape changes. A kriged map of sediment depths shows that no apparent relationship exists between both sediment accumulation depths and the spatial distribution of vegetation and between sediment accumulation depths and the density of vegetation. Comparison of the interpolated map to visually estimated flow patterns from 1973 shows that channel flow direction did not change. The present-day channel is approximately 13.7 m shorter downslope from its original length observed in 1973
