Public ISBD Titre de série : U.S. Geological Survey Water Supply paper, 2203 Titre : Investigation of the flooding in the Tug Fork Basin of Kentucky Virginia and West Virginia Type de document : texte imprimé Auteurs : Hirsch, R. M. ; Scott, A. G. ; Wyant, T. Mention d'édition : U. S. Geological Survey Editeur : U. S. Geological Survey Année de publication : 1982 ISBN/ISSN/EAN : CI-05099 Note générale : "Statistical analysis indicates that the average size of annual-flood peaks of the Tug Fork has been increasing. However, additional statistical analysis does not indicate that the flood levels that were exceeded typically once or twice a year in the period 1947 - 79 are any more likely to be exceeded now than in 1947. Possible trends in stream-channel size also are investigated at three locations. No discernible trends in channel size are noted. Further statistical analysis of the trend in the size of annual-flood peaks shows that much of the annual variation is related to local rainfall and to the ""natrual"" hydrologic response in a relatively undisturbed subbasin. However, some statistical indication of trend persists after accounting for these natural factors, though it is of borderline statistical significance."
