Flume experiments are typically conducted to reveal the detailed behavior of debris flows. Direct sampling at lower end a flume has been used measure sediment concentrations in experiments; however, direct measurements under non-steady or non-equilibrium conditions difficult. In contrast, image analysis methods can acquire spatiotemporal high-resolution data non-contact manner. this study, we w...

Previous studies on wave-induced pore pressure in a porous seabed mainly focused non-breaking regular waves, e.g., Airy linear waves or Stokes non-linear waves. In this study, breaking-wave induced response sandy was physically simulated with large wave flume. The generated by superimposing series of longer onto the foregoing shorter at specified location. Water surface elevations and correspon...

Nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. These types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. In the current study, the performance of floating breakwater (FBs) under regular waves was studied using the physical modeling method. For the mode...

application of structures of flow pattern modification is one of the erosion control methods in bends. triangular vanes are among these structures which provide less scour depth compared to the other techniques such as spur dike. since little information on erosion and sedimentation pattern around triangular vanes are available, this study was conducted to study the effect of structure effectiv...

The hydrodynamic processes associated with flow through vegetation have many implications for both natural and constructed wetlands. This study examined the effect of marsh grass on mixing rates. A flow visualization study was performed, using a laser light sheet and a video camera to obtain images of a plume of fluorescent dye. The study was performed in a laboratory flume, using wooden dowels...

Visualization of the website clickstream data has been a pivotal process as it aids in defining the user preferences. It includes the processes of gathering, investigating and reporting about the web pages that are being viewed by the users. Clickstream visualization is primarily employed by organizations which focuses on gaining the user preferences and improve their products or services towar...
