SURVEY OF VERTICAL FORMATION OF FLOW VELOCITY WITH RIPARIAN WOODS ON 2005-FLOOD IN BIBAI RIVER

Autor: Shuya Abe, Takashi Kuwamura, Yasuharu Watanabe

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 50:1147-1152

Riparian wood area is assumed to be dead water section on study for flowing ability. But, calculation results of water level might not correspond with observations on medium-small scale rivers. We surveyed about vertical formation of flood flow veloc

SUITABILITY OF WEAKLY NONLINEAR ANALYSIS TO MODE REDUCTION PROCESS OF DOUBLE-ROW BARS

Autor: Takashi Kuwamura, Yasuharu Watanabe

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 49:943-948

Weakly nonlinear analysis was adapted to the hydraulic experiments in order to clarify the mechanisms of mode reduction process of sand bars. Hydraulic conditions of this analysis were set large width-depth ratio. The following facts became clear by

RIVER BED CHANGE OF THE TOKACHI RIVER IN FLOOD, AUGUST 2003

Autor: Takashi Kuwamura, Yasuharu Watanabe

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 48:979-984

Field observation of bed configuration was conducted during the 2003 August flood at the Tokachi River. Radio controlled boat was used in this measurement. The aim of this observation is to clarify the change of bed topography during flood. It is fou

EXPERIMENTAL STUDY ON BAR FORMATION UNDER UNSTEADY FLOW CONDITIONS USING A WIDE WIDTH CHANNEL

Autor: Takashi Kuwamura, Yasuharu Watanabe

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 47:625-630

In rivers that have sections of single-row bar and sections of double-row bar, the occurrence mechanisms of bank erosion, sediment accumulation, and other phenomena differ between these two types of section. To determine which of these sections, non-

BIFURCATED FLOW RATE TO THE OXBOW MEANDER CHANNEL REGULATED BY A SMALL DAM IN THE SHIBETSU RIVER

Autor: Kazuyoshi Hasegawa, Masaki Fujita, Takashi Kuwamura, Yasuharu Watanabe

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 47:529-534

A project of river channel restoration has been promoted in the Shibetsu River, that attempts to restore the natural meander channel remained as a oxbow lake by letting the river water run through. In this project, it is intended that water streams i

DEVELOPEMENT OF THE BED-LOAD SEDIMENT OBSERVATION USING THE SOUND PRESSURE

Autor: Hideyuki Miyahuji, Takashi Kuwamura, Hisakatsu Yamazaki

Publikováno v: PROCEEDINGS OF HYDRAULIC ENGINEERING. 46:631-636

With problems caused by sediment manifesting themselves in recent years, the need for comprehensive sediment management has been rising increasingly. To solve these problems, the appropriate monitoring of sediment transport is imperative. Observation
