Abstract

Flood data from 205 unregulated rural drainage basins ranging in size from 0.012 to 5,993 sq mi were analyzed to determine whether main-channel orientation had any effect on flood peaks. No significant effect on flood peaks was found for unregulated rural streams in Ohio except for steep basins (main-channel slope greater than approximately 1 percent) that flow in nearly the same direction as the prevailing storm movement (less than 20-degree deviation). These basins in general produce higher flood peaks than those predicted by the U.S. Geological Survey regional regression equations for Ohio.
