5. Definition of Hydrology “Hydrology is the science dealing with the waters of the earth, their occurrence, distribution and circulation, their chemical and physical properties and their interaction with the environment”

6. This course encompasses major hydrological processes, including precipitation, evaporation, transpiration, rainfall interception, soil water, ground water, and runoff. The emphasis of this course will be on the basic principles of these physical processes forming the complete hydrological cycle at global, regional and watershed scales. A series of 4 assignments are given for students to gain practical skills in hydrological analysis. Course Outline

7. Why Do We Study Hydrology? Water is the essential ingredient of all life on Earth Natural Hazards Water Supply Important Component of Earth’s System Profound Human Impacts

8. Water Supply Dinking and sanitation Irrigation Industry and power generation Transportation Water supply is limited by the small fraction of fresh water on Earth, but the demand is increasing due to various reasons: Increasing population Increasing urbanization Increasing agricultural and industrial production The global demand for water is now about 3500 km 3 /year

9. Water is an important component of the Earth environment system 1. Biosphere Vegetation distribution Plant growth Indirect effects on global climate 2. Lithosphere Significant geomorphic agent Topography resulting from tectonics determines water distribution Plate tectonics determines distribution of oceans 3. Atmosphere Fundamental in redistribution of energy Most important “greenhouse gas” affecting climate Sea level

10. Human activities directly affect local, regional and global hydrology Direct effects of extraction (ground water, river water, lake water, etc.) Deforestation Urban development
