Question: The project flow rate determined according to the stream yield is Q=10 m3/s. According to the selected pavement type, the Manning coefficient was determined as n=0.017, the channel base slope 10=1/1500 and the slope slope m=3/2 from the topographic features of the land. Project flow will be transmitted through a trapezoidal cross-section channel. Determine the channel bottom width and water depth with the concept of the most appropriate section.

A 200-acre urban drainage area consists of three different watershed areas: 60% single-family, 30% neighborhood businesses, and 10% playground area. If the time to concentration is 2.00 hours, determine the depth of gutters needed in the development area if each gutter is to accept 1% of the total volumetric flow. The slope along the roadway is 0.0005 ft/ft and a gutter cross-section as shown in Figure 4. State all assumptions applied.
The structure and enclosed paved plaza of the BMW Zentrum building, located in Greenville, SouthCarolina, may be approximated as a 70-m diametercircle.

(c) Using the rational method, whatis the expected peak 25-year runoff from this facility? (d) What factors may contribute to the uncertainty of this runoff estimate?
In a separate region of the new E-W highway proposed by the Maine DOT an 18 ft. highway embankment will be constructed and overly a 10 ft thick layer of soft clay. The embankment will be compacted with an undrained strength of 800 psf and the soft clay has a measured strength of 450 psf. The DOT would like to maintain a factor of safety of at least 1.5. a.

(b) A catchment consists of an asphalt pavement that drains into a rectangular concrete channel. The asphalt surface has an average slope of 0.6%, and the distance from the catchment boundary to the drain is 50 m. The drainage channel is 30 m long, 25 cm wide, 20 cm deep, and has a slope of 0.8%. For an effective rainfall rate of 60 mm/h, the flow rate in the channel is estimated to be 0.025 m³/s. Estimate the time of concentration, te of the catchment. Hint: Use the Manning's in the kinematic wave equation form.
