Earth Dam: Types of Earthen Dam and its Construction.

SOLVED: "Building crescent shaped earthen embankment in level terrain is better than the construction of large dams across the river to store water. Analyse this statement with their effects.

SOLVED: Water has been leaking undetected from a reservoir formed by an earthen dam. Due to the accelerating erosion, the rate of water loss can be modeled by the function g(x)=-(1)/(4) x^2 8, x>0, where g(x) represents hundreds of gallons of water lost per hour. The area under the curve in the interval [0,5] then represents the total water loss in 5 hr. Using the rectangle method results in the expression (5)/(n)∑i=1^n[-(1)/(4)((5)/(n) i)^2 8] . Find the total amount of water lost by applying s
