This lesson begins an ongoing classroom scenario in which student engineering teams working for the Splash Engineering firm design dams for a fictitious client, Thirsty County. </summary><engrConnection>
		
			
				Human-made dams are important in our modern life. Civil engineers and city planners compare the benefits. cost and environmental impacts to determine whether a community could benefit from a dam.
