ABSTRACT
Data independent of the flood record may suggest that a flood record may not be stationary. Knowing that changes in land cover occurred during the period of record will necessitate assessing the effect of the land cover change on the peaks in the record. Statistical hypothesis testing is the fundamental approach for analyzing a flood record for nonhomogeneity. Statistical testing only suggests whether a flood record has been affected; it does not quantify the effect. Statistical tests have been used in flood frequency and hydrologic analyses for the detection of nonhomogeneity (Natural Environment Research Council, 1975; Hirsch, Slack, and Smith, 1982; Pilon and Harvey, 1992; Helsel and Hirsch, 1992).
