An 80 elevation would be 3 feet above the bottom of the excavation. The slope of the water table is 0.008, and the hydraulic conductivity is 80 feet per day (typical of a medium to fine sand) Assuming water flows in along all four side walls (equivalent to an area of 3 feet by 320 feet) and upward through the bottom (an 80 foot by 80 foot area), what pumping rate in gallons per minute, would be required to keep...

The height of a triangle is increasing at a rate of 1.5 centimeters/minute while the area of the triangle is increasing at a rate of 2.5 square centimeters per minute. At what rate is the base of the triangle changing when the height is 11 centimeters and the area is 92 square centimeters? Remember that you're using the formula for the area of a triangle: Area -bh (You'll need to know this formula in the normal homework assignments, quizzes and...

Problem 7.2.a) The Philip and Green-Ampt equations provide models for “infiltration capacity” (or “potential infiltration”). What assumptions are used in the development of the Philip and Green-Ampt infiltration capacity models? Clearly explain the difference between actual infiltration rate and infiltration capacity (potential infiltration). Under what specific conditions are the two the same? b) State the condition that for a given rainfall (or snowmelt) event would never generate infiltration excess runoff. This should be written in terms of the rainfall/melt rate...

Question 5 a. Estimate the life expectancy of a 55 ha site chosen by a city council to serve for sanitary landfilling of solid wastes generated by a design population of 300000. The solid waste generation rate is 2.0 kg/cap.d. The site can accommodate a compacted fill of final depth 6m. A density of 500 kg/m' is expected to be achieved in the compacted landfill. Estimate also the quantity of cover soil required to meet the needs of daily cover,...
