| Outline and Purpose of the Course | Human activities have significant impacts on water and element circulations of the modern Earth system. Thus, following to the explanation of various examples on nitrogen, carbon, and iron circulations, methodologies to analyze water and element circulations from the view point of ‘watershed’ will be lectured. Especially, we will focus on how to construct hydrochemical model and in detail explanation on it will be given. | |||
| Course Goals |
(1) Understanding the basic knowledge of water and element circulations. (2) Understanding the modeling method to analyze water and element circulations from the view point of watershed. |

| Schedule and Contents |
The following themes are scheduled to be lectured. The number within the【】is the approximate number of periods. (1) Planetary Boundaries and water and elements circulations on the Earth【2】 Modern era, sometimes called as ‘Anthropocene’, is the area where too large impacts of human being on the Earth system pushes the Earth system to the edge of the stability (Planetary boundaries). Based on this recognition, we will look through the modern water and material circulations, considering the importance of biogeochemical viewpoints. (2) Carbon circulation in watersheds【2】 Soil is the second largest carbon pool next to the ocean carbon pool. Thus, it is very important to quantify carbon budget of soils to reach accurate understanding of global warming. Carbon circulation in forest ecosystems, agricultural lands, and coastal ecosystems will be overviewed. (3) Nitrogen circulation in watersheds【2】 Nitrogen is considered as an important element in the planetary boundaries concept. Introducing nitrogen saturation in forests, nitrogen circulation in agricultural lands with respect to fertilizer application, how the mechanism of nitrogen circulation is explained. Then, a case of modeling of water and nitrogen behavior in the Ise Bay watershed will also be described. (4) Iron circulations which bonds lands and oceans【2】 Iron is one of the essential elements like nitrogen and phosphorous. Especially for the ecosystem of outer ocean, iron is critically important. As a typically case, the mechanism of the formation of dissolved iron and transport through rivers, coastal area, and oceans in the Amur-Okhotsk system will be lectured. (5) The modeling method of water and element circulations【2】 To better understanding of water and element circulation of the watershed as a whole, hydrochemical modeling is essential. Amongst various models, structures of TOPMODEL, SWAT, HYDRUS, and MODFLOW will be explained. In addition, how to choose an appropriate model according to the purpose of researches will also be lectured. |
