Student engineering teams assist a city that is building a new soccer field for the World Cup competition.  To protect the city’s precious groundwater, the city requires a field that is as environmentally sustainable as possible, but also meets the needs of professional players.  Students are challenged to design the optimum layered soil arrangement (soil horizons) as the base of the field.  Teams must design a soil horizon system that is absorbent enough to withstand a given amount of rainfall without leaving behind standing water or contaminating the city’s aquifer.  Utilizing mathematical calculations and a variety of materials, teams construct and test their team soil horizon design for its ability to endure stipulated rainfall and compaction criteria.
