1.What is the probability that a drought is more severe than a drought of a return period of once in 50 yr will occur exactly twice in 100 yr?
2.The elevation of water in well A is 300m above sea level and well B is 350m above sea level. The wells are 45m apart. A dye test reveals that the specific discharge between the two wells is about 2.75m/day. What type of aquifer material do you expect in this location?
3.A vertical parabolic curve isto be used as a sag curve, and it is desired to know the locationand elevation of the low point. The curve is 750-ft long,and the minus grade of 3.6 percent intersects the plus grade of 6.2percent at station 240 + 80.00. Calculate the low point of thecurve if the intersection at station 240 + 80.00 is at elevation426.84.
