Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.

Homework-help : The land use of the area and the corresponding runoff coefficients are given in the table. Find the runoff if the rainfall intensity is 100mm/hr. before and after converting 7 ha from lawn to industrial area. Then design the pipes for sewer system if he Manning coefficient is 0.012 and the relevant slope is 0.003m/m.
Rainwater runoff from a 200-ft by 500-ft parking lot is to drain through a circular concrete pipe that is laid on a slope of 3 ft/mi. Determine the pipe diameter if it is to be full with a steady rainfall of 1.5 in./hr.
Rainwater runoff from a 200 ft. by 500 ft. parking lot is to drain through a circular concretepipe that is laid on a slope of 3 ft./mile. Determine the pipe diameter if it is to be full with a steady rainfall of 1.5 in/hour.[Answer is in units of ft]
The Stormwater Control Measure (SCM) behind McMichael Science Center is 140ft long, 50ft wide, and has an average depth to the overflow riser of 3ft. The SCM was designed to capture the first 1 inch of rainfall flowing off the impervious surfaces in the watershed. What is the total surface area of watershed that flows to this SCM? (Hint: you can calculate the total volume of water in the SCM, then use that volume of water and the depth of rainfall to calculate the area of the watershed)
The length of a parking lot is L = 100 m, and it is sloped at So = 0.02. The surface of the lot is bare clay with a Manning roughness factor of n = 0.020. A rainstorm produces a constant rainfall excess at the rate of ?0 = 25 mm/hr. If td = 25 minutes: Determine the runoff hydrograph at the downstream end of the parking lot. Based on your answers in Step 1, draw your estimated hydrograph. ***Convert i0 to mJs. This conversion is not given and I cannot find it.
The structure and enclosed paved plaza of the BMW Zentrum building, located in Greenville, SouthCarolina, may be approximated as a 70-m diametercircle. Flow path length may be approximatedas the average of the diameter and a half-circumference. The average surface slope ofthiscombinedfacility is approximately 5 percent.(a) Compute time of concentration using the FAA equation. (b) Rainfall intensity for Greenville County may be computed by the formula i = a/ (b + t.)°, usingcoefficients in the following table. What is the expected 25-year rainfall intensity? (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?

Runoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.
A civil engineer is designing the outflow of a pond. The pond has a radius of r=200m,and the maximum sustained rainfall rate is v=2.1x10 -5 m/s, about 3 inches per hour. If theengineer makes the outflow with a cross-sectional area of A=0.5m 2 , what maximumvelocity will the outflow of water have during a heavy rainstorm if the surface level ofthe pond does not change?
Hope your help hydraulic question thanks (CE 340)
The area under consideration is 250 acres of open pasture and you intend to pave 30% with reinforced concrete. You determine that the time of concentration for this area will decrease from 3 hours to 40 minutes after the ramp is in place. Currently a grass-lined drainage ditch carries the runoff for the 250 acres. For runoff coefficients, use the highest published range value in the approriate category.a) If you design for a 50-yr storm, how much will the peak runoff flow rate change? Reportthe answer as a % increase in flowrate.b) Determine if the drainage ditch will still be capable of carrying the runoff once thepaving is complete.c) What happens if the drainage ditch is paved with float finished concrete? How deep isthe flow? n = 0.025s = 1%ymax = 3 ft
