Aquatic Resources (CINA 4157).

This class covers the basic principles of hydrology, geomorphology, water chemistry, stream and lake ecology, and water resources management.  It includes field trips to rivers, lakes, and to sewer and aqueduct systems.


Limnology (CINA 5540).

This is an advance class on limnology including both theoretical principles and laboratory practice.  It focuses on the studies of the physical, chemical and biological properties of inland waters (i.e., lakes, rivers, creeks, estuaries, and groundwater).


Fluvial systems: ecology and management (CINA 4995).

This course focuses on the ecology and management of rivers, particularly those in tropical islands.  It covers both theoretical and practical applications of stream ecosystem concepts, stream restoration, and water policy.
