1.A saturated 100 cm^3 clay sample has a natural water content of30%. It's found that the shrinkage limit occurs when the watercontent is 19%. If the specific gravity of soil solids is 2.7, whatwill the volume of the sample be when the water content is 15%?
2.The mean annual precipitation for a 325 mi2 watershed is25 inches. Assume that 20% of the annual precipitation reachesthe watershed outlet as streamflow. Determine the meanstreamflow rate in ac-ft/yr
3.A crop has a consumptive use requirement of 1.2 acre-ft of water per acre of crop land. The crop is planted on 780 acres. Precipitation is 3.2 inches. The remainder of the 1.2 ac-ft/ac requirement is met by irrigation. Determine the volume of irrigation water needed in ac-ft.
4.A field party is capable of making taping observations with astandard deviation of ±0.015 ft per 100ft tape length. Whatstandard deviation would be expected in a distance of 300ft tapedby this party?
5.The mean anual rainfall depth over a 280 km2watershed is 725 mm. What is the mean annual volume of rainfalling on the watershed in m3 ?
