  • To give the students knowledge of hydrological phenomenon, its processes and climate of Nepal
  • To acquaint with the role of microorganisms in environment
  • To enhance students' understanding on broader aspect of environmental science linking it with geology and biotechnology, and
  • To make students familiar about environmental survey and analytical techniques
