Experimental study on scour occurring at a vertical impermeable submerged breakwater

Prediction of non-breaking wave induced scour depth at the trunk section of breakwaters using Genetic Programming and Artificial Neural Networks

“…(3) includes the effect of the breakwater slope, while the effects of structural configuration, breakwater submergence and permeability, sediments properties and bed slope were not accounted for. Lee and Mizutani [16] investigated the scour at vertical submerged breakwaters. In agreement with Sumer and Fredsøes' [29] findings, they introduced the reflection coefficient as the main parameter affecting the scour depth.…”

“…Sumer and Fredsøe [29] attributed the difference between the maximum scour depth of vertical and rubble-mound breakwaters to the wave reflection. Lee and Mizutani [16] indicated that the effects of submerged depth, breakwater width and structural configuration can be effectively described by the reflection coefficient. Therefore, in this paper, the reflection coefficient (Cr) accounts for the effects of structural configuration, such as the breakwater slope (α), the submerged depth (h c ), the breakwater width (B), the size of armor stones (D 50 ) and the permeability of the breakwater (P).…”

“…Results of various studies showed that an increase in the wave height intensifies the sediment transport capability and ultimately leads to the large scour depths [16,29]. Here, the relative non-breaking wave steepness (H L / nb nb ) accounts for the wave characteristics effects on S max .…”

Determining Transmission Coefficient of Propagating Solitary Wave over Trapezoidal Breakwater and Parametric Studies on Different Influential Factors

“…Hsiao et al [5] also mathematically investigated reflection characteristics of composite breakwaters in facing incident waves. Lee and Mizutani [6] experimentally studied front local scour of submerged impermeable breakwater and presented a new method of estimation for evaluating scour depth. Also, Dhinakaran et al [7] studied effect of hydrodynamic characteristics such as transmission and reflection coefficients, dimensionless forces, and pressures on the semicircular caisson for different water depths.…”

Structural Damage Monitoring of Harbor Caissons with Interlocking Condition

“…Jabbari et al [7] used artificial neural networks to estimate scour depth around a vertical breakwater. Lee et al [8] investigated local scour in an impermeable submerged breakwater. However, those studies have examined only behaviors of mono-caisson systems.…”
