Determine the discharge for a stream with a total cross-sectional area of 2m2 and the wetted perimeter is 4m over a bottom slope of 1% if the roughness coefficient of the earthen material forming the stream is 0.035.
Design a 4:1 trapezoidal shaped vegetated waterway for a field in Sangamon County, Illinois for the given condition. The highest rainfall occurs during growing season after several days of dry period (antecedent rainfall condition is I). Hydrologic soil group is B. The grass waterway is designed to carry peak runoff rate from a 100-ha watershed, which has row crops on terraced lands with poor hydrologic condition, maximum length of flow is 500 m, and average watershed slope is 3%. The soils are highly erodible, and the waterway slope is about 4.5%. The vegetation is usually mowed (retardance group D), but the waterway should have adequate capacity when the grass is tall (retardance group B). Design for both cases. Provide final dimensions of top width, depth, and bottom width of the waterway. If any data is missing, make reasonable assumptions. (1) Estimate the peak runoff rate by the SCS TR-55 method from information provided above. Make reasonable assumptions, if any. (2) Follow the…
