Rain water falling to the ground surface will either runoff along the surface or infiltrate into the soil. As majority of catchments in Japan are mountainous catchments, it is necessary to estimate the potential water storage (water holding capacity) of each catchments for knowing the portion of rain water that can be stored in the catchment, and the portion of rain water that become surface runoff. For many years, civil and forest hydrologists have proposed several methods to estimate surface runoff. One method proposed by civil hydrologists is to estimate surface runoff by estimating water holding capacity distribution of each catchments. The variation of water holding capacity can be analyzed from many aspects such as catchment physiographic variables, rock type, soil type, terrain, and also climatic condition. On the other hand, one method proposed by forest hydrologist is to estimate surface runoff by tracer approach. In this session, researchs related to estimation water storage in mountains catchments are welcome. At the end of the session, the collaboration possibilities between forest hydrologists and civil hydrologists to address the same issue will be discussed. 英文 Estimating catchment storage for water resources management and flood risk reduction purposes is one of research target in hydrology area.
