Course Description

This subject deals with a wide range of basic knowledge on rivers required to make an integrated river basic management plan based on natural & social sciences and engineering. The contents included in the class are described as follows: various view-points in relation to river systems, long term environmental changes of rivers and their factors, river flows and river channel processes, structure and function of river and lake ecosystems, recent characteristics of flood disasters, integrated river basin planning including flood control, sustainable reservoir management, nature restoration, and sediment transport management.


regular examination, quiz in classes, attendance and reports

Course Goals

The objectives of this subject are to understand the basic knowledge to consider river environments from the various points of view such as flood control, natural environment conservation, water utilization based on natural science, social sciences and engineering & technology.
