An embankment construction requires the delivery of 38,200 m3 of the soil from a stockpile (d= 87 pcf, w=13%) to the construction site. the moisture content of the soil at the construction site is 9%. the compactors specifications indicate that the soil needs to be compacted to a minimum of 90% of modified proctor maximum dry unit weight. laboratory compaction tests yielded a maximum dry unit weight of 116 pcf. how much water (in cubic feet) must be added to the soil to increase its moisture content to the optimum moisture content of 14%

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
