Question: Consider a triangular grass - lined swale with side slopes of 3 : 1 ( horizontal: vertical ) and a longitudinal slope of 1 .

Consider a triangular grass-lined swale with side slopes of 3:1(horizontal: vertical) and a longitudinal slope of 1.0%. The Manning's roughness coefficient for the swale is 0.035. Calculate the maximum discharge that this channel can convey while maintaining a flow velocity below the erosive limit of 4fts.
