The following figure shows the cross-section of an anchored sheet pile wall. The soil properties
and some wall dimensions are shown in the figure and spacing between anchor rods is 2.0 m
(center to center). Design the wall using Rankine theory; i.e., calculate the depth of embedment
of the wall (D), tensile force on each rod
Q2: A circular concrete culvert of diameter 120 cm carries water of depth 75 cm to irrigate
a 30-hectare field. What could be the discharge of this canal if the slope was 0.002? Use
Manning's n= 0.014.
TWO
A farm of 40 hectares is supplied by open field drains. The spacing of these drains were selected to be
100m and the length of each drain is 600 m. If the drainage coefficient is 4 cm/day, find:
1- Discharge at the end of a field drain.
2- Total discharge passed through the collector drain.
3- The dimension of open drains, if n= 0.03, S= 0.00035 and Z= 1.5

Your task is to carry out a preliminary slope stability analysis for a planned road underpass beneath the new railway. The analysis concerns the eastern slope at the underpass. The designed clay slope has a depth of 12.5 meters and a width of 27.0 meters. According to geotechnical investigations, the soil consists of homogeneous, overconsolidated clay with a saturated unit weight of 15 kN/m³ and an undrained shear strength of 35 kPa. The groundwater table is at ground level (0.0 m). According to Figure 1, the most critical slip surface is circular, with the center of rotation (point O) located 4.0 meters above the current ground surface (0.0 m). The slip surface intersects the ground at the toe of the slope and 6.0 meters east of the slope crest.

Water enters a reach of rectangular channel where y₁ = 0.5 m, b = 7.5 m, and Q = 20 m³/s (Figure P10.39). It is desired that a hydraulic jump occur upstream (location 2) of the sill and on the sill critical conditions exist (loca- tion 3). Other than across the jump, losses can be neglected. Determine the following: (a) Depths at locations 2 and 3 (b) Required height of the sill, h (c) Resultant force acting on the sill (d) Sketch the water surface and energy grade line.

A rectangular, unfinished concrete channel of 30-ft width is laid on a slope of 7 ft/mi. Determine the flow depth and Froude number of the flow if the flowrate is 350 ft³/s.arrow_forwardQuestion 3. A lake discharges into a steep channel. At the channel entrance the lake is 4 m above the channel bottom. Neglecting losses, find the discharge for the following geometries: (a) Rectangular section, b = 4 m (b) Trapezoidal section, b = 3 m, angle = 60° (c) Circular section, d = 3.5 m.arrow_forward
- Question 7. A popular sharp-crested weir for use in low-flow situations is the V-notch weir, as shown below. When these weirs are designed, the equation for determining the flowrate by neglecting the velocity head of the upstream flow can be written as Q = CH", where C is a coefficient of discharge and is a function of the notch angle (0) and n is a weir constant. The constants C and n must be determined experimentally for a given weir. In logarithmic form, the weir equation is log Q = n log H + log C. Assume we have a flume in the lab where we can experimentally explore the relationship between Q and H for this weir by adjusting the flowrates. Develop an appropriate experiment to determine n and C' (the weir discharge coefficient) for the weir used. Write the experimental procedure steps and measurement readings that are needed to determine these coefficients empirically. Hint: Please refer to your lab manual.
