Estimation of Climatic Variations in Relation to Large-scale Atmospheric and Oceanic Interaction

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 66:1251-1255

Climate variabilities in characterictics of typhoon, annual precipitation and SST are investigated in connection with the indecies of atomospher- ocean interaction such as MEI, PDO, NAO and AO. Spectra of annual time serries of the climate indecies w

Autor: Syunji Inoshita, Takashi Izumiya, Yuichi Kobayashi, Jun Ishigaki, Kunihiko Ishibashi, Atsushi Wakamatsu, Tsunehiro Sekimoto, Kenya Takahashi

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 66:176-180

The propagation of infragravity waves in intermediate water depths near and in a port is investigated with field observations. A Green function method which is used for seismic interferometry is applied to estimate wave profiles of infragravity waves

Stochastic Forcing Model for the Generation and Evolution of Infragravity waves by Short Gravity Surface Waves

Autor: Takashi Izumiya, Makoto Kanai

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 65:221-225

A stochastic forcing model has been developed to estimate the heights of infragravity waves excited by short gravity surface waves. The model includes a wave equation for infragravity waves with the external force term due to pressure disturbances by

Estimation of a 2D Surface Current Field Using Radial Current Velocities Measured by HF Ocean Radar

Autor: Yuichi Kobayashi, Takashi Izumiya

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 65:1446-1450

A method for estimating a 2D surface current field has been developed by using radial current velocities measured by HF ocean radar. The method includes the second order partial differential equations in terms of a potential function and a stream fun

A New Criterion for Goodness-of-Fit in Extreme Statistics and Its Applicability

Autor: Hitoshi Shibuya, Takashi Izumiya

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 65:156-160

A weighted least squares method for extreme statistics has been developed to estimate the parameters of candidate distribution functions. The method employs variances of the order statistics of extreme data, which are analytically evaluated by virtue

Evaluation of a Cross-shore Outflow Rate of Suspended Sediment

Autor: Takashi Izumiya, Masatoshi Izumi

Publikováno v: PROCEEDINGS OF COASTAL ENGINEERING, JSCE. 55:721-725

A cross-shore outflow rate of suspended sediment is important in estimating coastal sediment budget. On estimating an outflow rate, vertical distributions of concentration of suspended load were evaluated as a function of bottom friction velocity due
