A. Research Activities(2003.1-2004.3)
A-1. Main subjects
a) Mechanism of sediment movement
Basic research has been carried out on debris flow, flash flood, and shallow landslide. The relationship between shallow landslide and underground pipe flow and the flow in bedrock are studied particularly.
b) Countermeasures to prevent or reduce sediment disasters and the Sabo-planning being compatible with environmental concerns. More effective permeable dams are experimentally investigated in order to store the excessive sediment and, at the same time, not to damage the eco-system established in the streams. A function of a series of slit sabo dams was studied by flume experiments and computer simulation. Influence of released sediment from sabo dams to downstream environment is investigated by field experiments.
c) Forest influence on the hydrologic cycle
Elements controlling hydrologic cycle in forest are studied. Effects of forest soil hydraulic properties on water discharge from forested watersheds are analyzed by laboratory experiments, field measurements, and numerical simulation methods. Evapo-transpiration is one of the major factors. Models to interpret the phenomena are built.
d) Environment of mountain streams
Pools in mountain streams play an important role as habitat for fish. The geometrical and hydraulic features of pools are investigated and the situation of habitat of fish is observed. The formation process of pools is investigated theoretically and observationally with a focus on step-pool system in mountain streams.
e) Sediment movement and integrated sediment management in river system
Sediment production process and sediment movement process in mountain region are investigated using a video camera system and turbidity meters. A numerical model for calculating sediment routing is also developed. Using these results, the sediment management for mitigating sediment-related disaster and providing better natural environment from mountains to seashore is studied.
f) Sediment related disasters
Debris flow disasters were surveyed in Venezuela where debris flows and landslides occurred in December, 1999. Following debris flows from landslides, landslide dams and other damages by September 21 Taiwan Earthquake were surveyed in the field. Mudflow was studied in Miyake Island after eruptions.
g) Buffer green belt against sediment hazards
The effects of trees against debris flow and landslide are studied to design buffer green belts. Infiltration and water storage characteristics are studied in different tree kinds.
