SUMMARY AND EVALUATION OF METHODS FOR DETECTING HYDROLOGIC CHANGES
HYDROLOGIC CHANGE DETECTION IS TAKEN TO MEAN ANALYSIS OF HISTORICAL RECORDS TO ESTABLISH THE PLAUSIBILITY OF NONHOMEGENEITY OF DATA. SUCH NONHOMOGENEITY IS CONVENTIONALLY ASSOCIATED WITH WATERSHED PHYSICAL CHANGE. A CHANGE COULD OCCUR IN ANY RECORDED OR DERIVED ITEMS OF DATA. THEREFORE, SUMMARIZATION OF METHODS FOR DETECTION IS NOT GIVEN SPECIFICALLY FOR SELECTED VARIABLES. RATHER, A GENERAL DESCRIPTION OF DATA PROVIDED BY EXPERIMENTAL HYDROLOGIC DESIGNS IS GIVEN. GENERAL MODELS AND SELECTED ILLUSTRATIONS ARE GIVEN FOR DIFFERENT TYPES OF DATA. IT IS SHOWN THAT THE CONVENTIONAL STATISTICAL METHODS OF DISCRIMINANT AND REGRESSION ANALYSES ARE SUITABLE FOR MANY SITUATIONS. AN EVALUATION OF ANY METHOD FOR DETECTING CHANGE IS PROVIDED BY EXAMINATION OF ITS CONFORMITY TO THESE OR OTHER CLASSICAL STATISTICAL METHODS. /AUTHOR/
