River Water Quality and Landscape in the Kumena and Tatau Basins, Sarawak, Malaysia Keitaro Fukushima 　(Field Science Education and Research Center, Kyoto University) 　River water quality is a very useful indicator of upstream terrestrial environment including land use, geology, lifestyle, development of infrastructure, and so forth. For example, the concentrations of calcium (Ca2+), magnesium (Mg2+) ions and dissolved silica (Si) are mainly controlled by underlying bedrock geology; nitrogen (N) and phosphorus (P) concentratios reflect land use such as agriculture and urbanization; and chloride ion (Cl–) concentration is likely proportional to the distance from the sea. Mines, factories, and livestock facilities can discharge high concentrations of N, P, certain metals, and […]

Cross-Disciplinary Research Workshop Date：June 7 (Thu.), 2012 14：30～17：00 Speaker： Keitaro Fukushima “The factors attributing water quality change in the running out process of the river” Speaker： Osamu Kozan “The land surface hydrology model in the Southeast Asian archipelago” Place：Center for Southeast Asia Studies, Kyoto Univ. First Floor of East Build. Conference Room 　This time, two of our program members will talk on the topic of “water.” 　This will be the first time for Mr. Fukushima and Mr. Kozan to lay out their works in Cross-disciplinary research workshop. We believe this will be a great opportunity to deepen the knowledge of “water” by listening to their hands-on research activities. 　Please join […]
