Spread Calculation in Composite Gutter Sections

Abstract

A generalized chart is presented to determine the spread in composite gutters given the gutter discharge. The use of this chart eliminates the tedious trial-and-error calculations to determine the spread in routine pavement drainage problems. The chart is also different from those available in the literature in the sense that it is limited neither to a specific unit system nor to specific gutter dimensions. The use of the chart is demonstrated through a practical application.
