[ABSTRACT] In brackish lakes and tidal rivers where a stable stratification with a sharp halocline usually exists, a characteristic aquatic environment often appears. One of serious environmental problems is an appearance of anoxic water mass in the

A new type of water sampler was designed for the sampling of groundwater from differentdepths in slender boreholes. It is of cylindrical shape with a diameter slightly smaller than thatof the borehole. When the sampler is going down in a borehole, wa

Large scale landslides induced by earthquakes in the historical years are investigated torestore the landslide topography to the original state, to reveal the origin and the mechanism, andto estimate the extent of the damaged area. The landslides dis
