• Abstract:
  Drainage area, slope, and mean annual precipitation were the only ; factors that were statistically significant at the 95-percent confidence ; level when the characteristics of the drainage basins were used as independent variables in a multiple-regression flood-frequency analysis of ; natural, unregulated streams in Texas. The State was divided into six ; regions on the basis of the distribution of the residuals from a single ; statewide regression of the 10-year flood. Equations were developed for ; predicting the magnitude of floods with recurrence intervals of 2, 5, 10, ; 25, SO, and 100 years in each of the six regions. These equations are ; applicable to unregulated rural streams with drainage basins ranging in area ; from 0.3 square mile to about 5,000 square miles in some regions. Regression equations were not developed for several areas, particularly in south ; Texas, because of the lack of definition of the flood-frequency characteristics.
