A railway fill is 12 m wide. The ground is level in a direction transverse to the centerline. The sideslope is 1.5:1. The center heights at 20 m interval are 3.7 m, 2.6 m, 4.0 m, 3.4 m, 2.8 m, 3.0 m, and 2.2 m. Determine the volume between section 1 and 2.

Design a most economic trapezoidal section of an irrigation canal Page 2 of 4 passing through non-alluvial soil having the following data. Assume reasonable values of bed slope and freeboard for the canal. Discharge of the canal = 20 cumec Permissible mean velocity = 0.85 m/s Bazin's constant, K = 1.3 Side slope = 1.5:1 Also calculate the percentage of earthwork can be saved if the canal is to be constructed as a lined one. Consider K=0.5 for the lined section. Given equation, A= 2.088 D² and P-4.176D for 1.5H:1V lined sections. Bazin's formula, C=87/(1+K/VR)

Soil of a burrow pit has a dry density of 17 kN / (m^3). How many m3 soil will be required to construct an embankment having a volume of 100 m^3 with dry density of 16 kN/m3?
