Isolated on a high plateau, the Los Alamos National Laboratory seemed an ideal place to store a bomb factory's deadly debris. But the heavily fractured mountains haven't contained the waste, some of which has trickled down hundreds of feet to the edge of the Rio Grande, one of the most important water sources in the Southwest … monitoring of runoff in canyons that drain into the river has found unsafe concentrations of organic compounds such as perchlorate, an ingredient in rocket propellent, and various radioactive byproducts of nuclear fission. “Much surface contamination … moves down into groundwater. That subterranean migration poses the greatest long-term danger to drinking-water wells and ultimately the Rio Grande. One of the canyons where radioactive waste has been found joins the Rio Grande just three miles above a diversion project the city of Santa Fe is building to capture nearly 3 billion gallons of water annually from the river” a. Assuming homogeneous hydraulic conductivity, no pumping wells, and steady state conditions, identify the governing equation and boundary conditions that would be used to approximate the rate of groundwater flow from a surface deposit of contaminated water to a nearby river canyon. Identify all terms and state all assumptions.
b. recognizing that the material is both porous and fractured, how might you characterize the hydraulic conductivity given the mean grain size and the average thickness of the fractures ?
On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak-hour factor is 0.90, and all drivers are regular users.
Water flowing in a wide channel of depth 35 cm undergoes hydraulic jump that resulted in energy dissipation of 72%. Estimate (a) the downstream depth, (b) the volume flow rate per meter of width.
An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. For this water main calculate the head loss
The line of sight of a level falls at a rate if 0.122ft/ 100 ft when the level bubble is centered. A backsight of 4.782 is taken on point A, which is at 75 ft from the level. the elevation of a is 425.238 ft.
Design a one way slab to support a uniform live load of 300 psf. The beam is simply supported with a span of 20 ft. Use a reinforcement ration ( Ps) of 0.008 Use f'c=3000 psi and fy=60000 psi.
Three stock car drivers are racing around a circular bend. They are each circling the bend at different radii: r(1)=249 m , r(2)=255 m , and r(3)=261 m . At a given instant, all three are traveling at the same transverse rate of rotation
A water contains a suspended solids concentration of 10.30 mg/L. Coagulation reduces this to 1.0 mg/L. To accomplish this, an alum dose of 13.30 mg/L is necessary. What is the dry weight of sludge produced in kg/day if the plant treats water at a rat..
The beam over a 3ft wide outside door is to be concrete to support the brickwork above the door. The moment has been calculated to be 4005in-Ibs and the beam is 4 inches wide and 6 inches overall height.
A small blimp is temporarily moored wherein DC and the centerline of AB are coplanar. A force F from wind, weight, and buoyancy is shown acting at the centerline of the blimp. If F = 5i+ 10 j + 18 k kN
A reservoir with a length of 20 km and width of 3 km has a flood inflow of 1000 m^3/s. (a) If exit flow is restricted to 500 m^3/s, how fast is the water level rising in the reservoir per day
Write a User Defined Function named SimpleCharacter that takes the character inputs either "Coffee" or "Tea" and returns the outputs High Octane for an input of "Coffee" and Low Octane for an input of "Tea".
