• Resumen

  • Students in a water resources engineering course consider the infiltration of water into soils, a topic through which instructors can reinforce many fundamental engineering principles. In this paper, undergraduates used two 80 minute classes to explore Green-Ampt infiltration through integration, differentiation, Newton-Raphson numerical methods and Visual Basic programming. Students used calculus software to check solved problems, programming software to modify and execute model code, and spreadsheet software to examine model outputs. Outputs included tables and graphs showing infiltration for a single precipitation event. Student assessment of the lesson is used to complement measurement of curricula outcomes and satisfy the US Accreditation Board of Engineering Technology criteria.
