experimental assessment of sediment transport and bed formation of sandy beaches by tsunami waves
all experiments in this study were carried out in a flume which was located in the hydraulic laboratory of technical faculty in guilan university. the wave flume was 12 m long, 0.5 m wide, 0.5 m high and equipped with a wave-producing system and ultrasonic sensors. the objectives of current experimental study are to investigate sediment transport, bed formation and sustainability of sandy beach...
متن کاملLegacy sediment: Definitions and processes of episodically produced anthropogenic sediment
Extensive anthropogenic terrestrial sedimentary deposits are well recognized in the geologic literature and are increasingly being referred to as legacy sediment (LS). Definitions of LS are reviewed and a broad but explicit definition is recommended based on episodically produced anthropogenic sediment. The phrase is being used in a variety of ways, but primarily in North America to describe po...
متن کاملSediment patches, sediment supply, and channel morphology
Bed surface particle size patchiness may play a central role in bedload and morphologic response to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of bedload transport, surface grain size, and channel profile with two previously published flume studies that documented bed surface response, and specifically patch development, to reduced sediment sup...

متن کاملSediment Waves and Gullies Generated by Turbidity Currents
Our objective is to improve our understanding of the genesis of large-scale bed forms similar to those observed in various submarine settings, and thought to be created by both confined and laterallyspreading turbidity currents and related dense underflows in continental slopes and rises. Two types of bed forms are the main focus of this work. First, slope gullies, which are parallel, evenly-sp...
