Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.

The hydraulic conductivity of a homogeneous gravelly aquifer is 3 x 10-1 cm/sec. The hydraulic gradient (groundwater surface slope) of the phreatic (water table) aquifer is 0.01 and the aquifer's effective porosity is 0.25. Calculate the following two parameters and provide the answer to question b) in the space provided (numerical answer only, no units or any). Calculate the specific discharge that represents flow conditions of the aquifer in cm/sec. Also Calculate the approximate average velocity of a conservative solute dissolved in this aquifer, calculated to units of cm/sec (enter numerical answer without stating units).
A discharge of 0.15 cumecs is supplied into a canal at the head and 0.1 cumecs is delivered to field having an area of 1.5 hac. The Irrigation is started at a moisture extraction level of 60% of the available moisture and then extends for 10 hours. Determine the following efficiencies: water conveyance, water application, water storage, and water distribution. The following information are known: effective depth of r.z. = 1.7 m, runoff loss in the field = 425 m3 , water penetration depth varies linearly from 1.7 m at the head end of the field to 1.1 m at the tail end, W.H.C. = 25cm/m depth of soil.
2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.
A drainage basin has a area of 7322 km2. The average annual precipitation for this area is 909 mm. The average surface water flow at the outlet of the catchment is 21.4 x 108 m3/year and the average groundwater flow out of the basin is 94.6 mm/year. Assume trailing zeros are significant if present. Determine the annual average evaporation in mm/year. (give your answer to one decimal place)
Problem 1. Consider a drainage system that consists of horizontal drains located at an elevation ho above the base of an unconfined aquifer of thickness b 10 m (see Figure 1). The recharge rate is r = 100 mm/yr, and the hydraulic conductivity of the aquifer is K = 1 m/d. The design condition of the drainage system is to avoid ponding at the ground surface. You can ignore the vadose zone for this problem. 1. Obtain the relation between the half-distance between drains, L, and the elevation of the drains, ho. Plot this function over the range of feasible lengths. 2. The cost of each individual drain can be split as the cost of the material (fixed) and the cost of installation (which is assumed to be proportional to the depth b – ho). If the fixed cost is $500 and the installation cost is $100 per meter of aquifer length per meter of depth, can you build a drainage system for less than $1 per meter of aquifer length? If so, what depth ho and spacing 2L would you choose? K= 1 m/day 2L = r…
