This course will expose students to the field of physical hydrology in the forest ecosystem. Detail discussion on the water cycle components will help students to understand the importance of each process involved, and able to apply the knowledge further in the management of forest or specifically in water catchment area. Students will also be taught how to do hydrological data observation for example, rainfall, interception, infiltration, evaporation and river discharge. Other topics that will also be discussed are variation in the weather, climate change, monitoring and water quality analyses and human impacts on hydrological regime.
