WebThis condition is common for larger basins that are above 300 m (1000 ft.) in elevation and is automatically accounted for in the USGS regression equations. For small basins where the rational method is being used, the designer should increase the runoff coefficient to reflect the reduction in infiltration and resulting increased surface runoff. WebSummary. North Dakota is divided into three hydrologic regions (fig. 1). The regression equations developed for these regions are for estimating peak discharges having recurrence intervals T that range from 2 to 500 years. The explanatory basin variables used in the equations are contributing drainage area (CA), in square miles; and main ...
