Army to Show Flood,Drought Farmers from the local area will find the Army ROTC exhibit at the Engineering Exposition this Saturday interesting and helpful because it shows the two extremes of weather, flood and drought. The cadets will have models set up to show the effects of these two weather circumstances which destroy great quantities of crops and land each year. The two models are set up in quarter hemispheres to show the condition of the sky and ground area in each of these conditions. The flood display has falling water to represent rain with the water running through the rivers on the exhibit giving the effect of true flood conditions. The drought display has a lighting setup to give the effect of dust and heat on the burned land below. Pictures of other flood and drought areas showing the work of the Army Corps of Engineers building dams and irrigation canals are placed around the exhibit.
