what is the purpose of providing bed slope in open channel
Depth–slope product The depthâ€“slope product is used to calculate the shear stress at the bed of an open channel containing fluid that is undergoing steady, uniform flow. It is widely used in river engineering, stream restoration, sedimentology, and fluvial geomorphology. It is the product of the water depth and the mean bed slope, along with the acceleration due to gravity and density of the fluid.
High Line The park is built on a disused, southern viaduct section of the New York Central Railroad line known as the West Side Line. Originating in the Lower West Side of Manhattan, the park runs from Gansevoort Street – three blocks below 14th Street, in the Meatpacking District – through Chelsea to the northern edge of the West Side Yard on 34th Street near the Javits Center.[4] The West Side Line formerly extended south to a railroad terminal at Spring Street, just north of Canal Street. Most of its southern section was demolished in 1960,[5] and another small portion was demolished in 1991.[6] The High Line was inspired by the 3-mile-long (4.8 km) Promenade plantée (tree-lined walkway), a similar project in Paris which was completed in 1993.[7][8]
