Abstract:
Based on the results of field surveys, coastal dike failures caused by the Great East Japan Earthquake were classified into eight patterns. The results of hydraulic model experiments related to major failure patterns reinforced the proposed failure processes. In addition, the aggregated length of each failure pattern showed that failure from scouring at the landward toe is the dominant failure pattern.

Abstract. Water flowing in the river causes a scouring event that occurs at the bed channel. The existence of scouring will increase along with changes in the geometry of the river and obstacles such as the weir which are followed by local scouring around the weir. Local scouring often occurs downstream end of weir sill which weakens its construction. Scouring measurement was conducted to monitor the pattern of scouring that occurs. By using Surfer software, the scouring visualization through the Data Grid and 3D Surface can be seen. In this research, scour monitoring in the laboratory using o

Abstract:
Hydrodynamics is a common manifestation that causes natural scouring of riverbeds, and it is one of the factors that exacerbate the natural disasters of local scouring of bridge piers, causing sustainability of environmental changes in the water. The evolution pattern and scour characteristics of the bed surface around the submerged structures under different scouring conditions vary greatly. In order to investigate the scour mechanism, the reformed group (RNG) turbulence model in computational fluid dynamics (CFD) simulation software (v11.2) was used to simulate the scour under the clear-wate

The investigation shows that the blockage of the culverts has influenced the scouring pattern at the blocked culverts' entrances. Ten experiments were carried out at the laboratory to see how blockage impacts the scouring pattern upstream of a box culvert during steady flow. Both partially blocked and unblocked cases were implemented in this study. The experimental tests were do

As quality requirements get lower and lower, the quality of buckwheat grain meant for buckwheat groats is deteriorating. The most typical example is winter buckwheat grain. Buckwheat grain has to be sorted according to various fractions before scouring. Thus, the mechanical properties of these fractions remain a relevant field of study. The research features the dynamic pattern in the mechanical properties of the main fractions of winter buckwheat grain according to fraction before and after storage. The research subject is fractions of buckwheat sorted according to grain size before scouring.

In this paper the offset jet entering a domain with a movable bed is simulated by the computer program FLUENT. To achieve this aim, sediment transport is numerically simulated using multiphase systems and the empirical coefficients are studied theoretically. The numerical results are verified by comparing the simulated total load with that obtained using existing formulae and concentration profiles from available measured data. In the final step, the offset jet scouring pattern is modeled qualitatively.Key words: offset jet, numerical simulation, FLUENT, multiphase system, turbulence, sediment

Abstract The analysis of local scouring around bridge piers currently is based on typical river flood discharges. However, extreme events like flash floods with high velocity and discharge, carry wooden debris that accumulates upstream of the bridge pier. This results in additional forces due to flow diversion and reduction in flow area, so impacting hydraulic structures and exacerbating the scouring process. The study objective was to examine the impact of debris transported by flash floods on the depth and distribution patterns of scouring around bridge piers. This research was conducted in

Nowadays, scouring has become an important issue in coastal engineering. Exposed to a flow, piers of different structures will continually be in danger of scouring. Thus, design of cross-sections for piers in order to produce the least turbulence in the flow passing the pier is a significant concern from hydrodynamical and structural points of view, in so far as the status quo studies concerning optimum pier cross-sections have engaged a major portion of civil engineering researches.

Abstract:
Icebergs and ice ridges frequently scour the surface of seabed deposits. Ice scouring can be problematic for offshore pipelines and other seabed installations. In order to reduce the risk of failure, pipelines are buried in the seabed. However, a stationary or moving ice feature could cause a significant increase in stresses and deformation in the seabed soil deposits below the contact surface between the soil and the ice, and consequently, might result in structural failure of buried pipeline. Safe burial depth for pipelines has been the subject of both experimental and numerical studies. In

There are many reports about failure of bridges around the world due to scouring. This shows the importance of research on scouring and any possibility on scour protection. The method used of control of scouring around the bridge piers can be divided in two categories, namely: Direct and Indirect methods. The first method may be done by increasing the streambed resistance. This is usually done by riprap around piers. Indirect control, however, can be achieved by changing the flow pattern around a pier. The second method can be done for instance by using a collar around the pier or using a slot

Bridge scour is the erosion of sediment around bridge piers by flowing water, causing a significant risk to bridge stability and safety. Scour depth, the extent of sediment erosion around bridge piers or other structures caused by flowing water, is a critical parameter in bridge engineering. Generally, there are three types of scour phenomena that impact the performance and safety of bridges as local scour, contraction scour, and degradational scour. Understanding these are essential for identifying and reducing any dangers to the stability and safety of bridges. This research aims to investig
