We carried out a hydraulics experiment for tsunami in ice-covered river. This research clari ed the following things. The pressure propagation velocity of a x-ice case is rapid as compared with an open-water case and free-ice case. This velocity of free-ice case becomes later than open-water case. In free-ice case, the pressure propagation velocity becomes late when ice-size becomes smaller. The pressure attenuation of a x-ice case is largest. If ice-size becomes small, pressure will not attenuate. When ice-size is small, the dispersion wave train of the same phenomenon as open-water case happens. On the other hand, When ice-size is big, It stops that dispersion wave train happens.}, pages = {375--380}, title = {河川結氷時における河川津波の圧力伝搬速度と圧力減衰特性}, volume = {19}, year = {2013} }
