| Abstract: | Measurements at bankfull stage were made at 136 sites in Idaho to determine whether predictions of flood discharge using channel-geometry characteristics are as good as or better than predictions using basin characteristics. These measurements are used to determine the variables of bankfull width, area, depth, and velocity. These variables are combined with basin characteristics for the sites, and multiple-regression techniques are used to select the best combination of variables to estimate the 10-year flood. To achieve the lowest standard error of estimate, the data set is divided into segments based on percentage of forest cover. Generally, discharge estimates obtained from equations using channel characteristics have smaller standard errors than those using basin characteristics. (USGS) |
