Longitudinal slope vs cross slope
Web29 de dez. de 2024 · Slope of swale: The longitudinal slope of a dry swale may vary from 0.5 to 2 percent and will affect the selection of swale type. It is HIGHLY RECOMMENDED that the design engineer consider the expected watershed flow to be conveyed by the swale in making the preliminary determination of design type. WebA cross slope should not normally exceed 3 percent on a tangent alignment unless there are three or more lanes in one direction of travel. In areas of intense rainfall and where …

Drainage gradient (DG) is a term in road design, defined as the combined slope due to road surface cross slope (CS) and longitudinal slope (hilliness). Although the term may not be used, the concept is also used in roof design and landscape architecture.
