13.(LAB) A discharge of 25 m3/s is passing in a rectangular channel of bed width 8.0 meters and water depth 3.0 meters. The channel bed width is gradually contracted from 8.0 meters at section (1) to 6.0 meters at section (2). In the contraction zone, a smooth hump is placed in the channel in which the bed level is gradually increased by 1.00 m. Determine: (i) The change in water levels, (ii).The minimum height of hump so that y2 = yc, and (iii) The change in water levels if the hump height is 1.50 meter

Question 1 The storage - outflow relationship for a small dam is given in Table 1. The inflow hydrograph for the uncontrolled spillway of this dam is tabulated in Table 2. Determine:

  1. the outflow hydrograph from the spillway (fill the table and add more rows if necessary),
  2. attenuation, translation, and lengthening in the base time of the outflow hydrograph.
  3. Draw inflow and outflow hydrographs on the same figure and show the parameters asked in part b on this figure (draw in Excel and paste it here).
  4. Comment on the location of peak discharge of outflow hydrograph, i.e. why is it coincident with the inflow hydrograph?

Hint: Use Table 1 values to obtain S=f(Q).

Do a free-hand drawing, using single lines for ramps,for the type of interchange you would recommend for each of the following scenarios:

A.A freeway crossing an urban street,with a desire to use a Diamond but not to disrupt the through traffic on the arterial with at-grade intersections.

B.Two US Primary highways crossing in a rural area. Dedicated ramps desired for each turning movement.

C.Same as scenario B, except the NE and SW quadrants are not to be used. However, at grade intersections are allowed on the N-S road.

D.An urban arterial ending at a freeway(T-intersection) with the heavier movement being from the freeway to the arterial.

Reciprocal levelling is done to test a dumpy level, along a chain line, at a common interval of 15m, starting at 135 m. The following records have been observed with the instrument shifts at distances of 180 m and 240 m:

3.400, 2.315, 1.350, 0.755, 3.305, 2.880, 1.745, 1.470, 1.910, 1.355, 2.450 and 3.035 m

Calculate the reduced levels at all the points and check for mathematical errors, assuming RL = 97.935 m is the bench mark reading at the first station. Use both a) the rise and fall method, and b) the height of collimation method.
