High levels of fecal indicator bacteria (FIB) consisting of total coliform (TC), E. coli (EC), and enterococci (ENT) bacteria indicate the presence of fecal contamination in the surf zone. Previous studies indicated possible tidal influence of flood control channels on the coastal water quality. As part of a class project, 14 undergraduate students, consisting of Chemical Engineering and Environmental Engineering majors, performed this study during rising (flood) and falling (ebb) tides, and showed the distribution of FIB in flood control channels. While the students were exposed to field work and laboratory procedures for the water quality, the results have important implications in the design of the diversion systems during dry weather.
Once viewed as being a sub-set of civil or chemical engineering, the discipline of environmental engineering has established a status in its own right worldwide1-3. The industry requires that new graduates have both increased knowledge in the field and capability to respond to public health and environmental protection issues4 . In order to improve teaching-learning process active and interactive participation of the students is preferred over traditional lecture-based teaching process. This type teaching style is found to be more appealing to students with diverse learning styles5 .
In dry weather periods urban runoff generated by street cleaning, car washing and landscape irrigation has shown to contain high levels of FIB. Previous studies6, 7 indicated that urban runoff can be the source of elevated surf zone levels of FIB at Huntington State Beach and Huntington City Beach in California. Sanders et al.8 modeled tidal transport of urban runoff in flood control channels using the finite-volume method to understand the transport of pollutants toward the
