Plot the drying-path SWRCs of a sandy soil and a clayey soil using the model of Lu (2016) using representative parameters for these two soils from this paper. Use equations (3), (9), and (12), and the"proposed" parameters in Table 2 (note that y, in this table is the same as ye in the equations). Also plot the individual contributions to water retention for capillarity and absorption (0c and 0a versus suction) for both soils, and comment on their relative contributions to water retention for the two soils.

Thank you!arrow_forwardAn unstretchable cable with mass per unit length 5 kg/m is hanging between points A and B. The horizontal distance between A and B is 20 m. The vertical distance is 15 m (B is in a lower position). We measure a point on the cable which lies by a horizontal distance of 5 meters to point A. It is found to be 4 meters lower than point A. The shape of the cable is almost straight.Use the small sag approximation (Lecture 5) and keep the accuracy to O (e) to estimate the horizontal load H on A and B.arrow_forward

- Use Burdine's (1953) equation from the handout (the statistical capillary tube model equation with the values of b, r, and m assumed by Burdine) to mathematically derive a relationship for the hydraulic conductivity function that is based on the SWRC model of Brooks and Corey (1964).arrow_forwardQuestion 2 A sluice gate controls flow in open channels. At sections 1 and 2, the flow is uniform and the pressure is hydrostatic. Neglecting bottom friction and atmospheric pressure, calculate the velocities V1 and V2, and the horizontal force, F, required to hold the gate if h1 = 6m, h2 = 1m, and b = 5m. h₁V₁ Sluice gate, width b Farrow_forwardQuestion 1 A pipeline 30 m long connects two tanks which have a difference of water level of 12 m. The first 10 m of pipeline from the upper tank is of 40 mm diameter and the next 20 m is of 60 mm diameter. At the change of section, a valve is fitted. Calculate the rate of flow when the valve is fully opened assuming that its resistance is negligible and that f for both pipes is 0.0054. In order to restrict the flow the valve is then partially closed. If k for the valve is now 5.6, find the percentage reduction in flow. Note the following Reservoir I Segment of Length Pipeline B Diameter (m) (mm) ABC AB 10 40 BC 20 60 Head loss due to friction h₁ = KQ² Valve fl K = 3.028D' Where, •h₂ = k Head loss due to partial closure (VAB-VBC) 2g Reservoir 2 H-12 marrow_forward
- Civil engineering students performed an evaluation of the two primary methods of classification (supervised and unsupervised). The evaluation of the two methods utilized the error matrices. Tables 1 and 2 represent supervised and unsupervised methods respectively.
