“…Hotta and Horikawa (1990) confirmed this argument and also found that it took less time for the denser fences to become buried by the dunes and thereby lose their trapping function. Thus a more porous fence has a longer life span (Fig.…”

“…After measuring the volume of the trapped sand after deployments of eight or nine months, he argued that fences with 25% porosity have a greater trapping volume than those with 50% porosity. However, a later wind tunnel experiment (Hotta and Horikawa, 1990) with slat-type fences (h Â w = 90 mm Â 2 mm) of porosities ranging from 0% to 50% installed on a flat sandy surface with 0.3 mm grain size, indicated that fences with 40% porosity trapped greater volumes of sand at faster rates than comparable fences with other porosities (Fig. 10).…”

“…The numerical simulation by Phillips and Willetts (1979) indicates that the height of the fence appears to have little effect on the location of the newly developed dune because the sediment transport processes occur within saltation layers whose height is usually less than the fence height. However, fence life span is proportional to its height (Trossel, 1981) because the fence will gradually lose its trapping function once the newly formed dune grows to 80% of the fence height (Hotta and Horikawa, 1990). Thus the magnitude of the dune is usually controlled by the fence height (Alhajraf, 2004).…”

“…Kerr and Nigra, 1952;Hotta et al, 1987;Grafals-Soto and Nordstrom, 2009). The first is trapping sand to initiate foredune development perpendicular to wind (Snyder and Pinet, 1981;Hotta and Horikawa, 1990;Miller et al, 2001). The second, in occasional cases, is to reorient the wind to intensify scouring tangent to the prevailing wind (McLaughlin and Brown, 1942).…”

“…The amount of infilling needed in the LWD matrix, relative to the storage depth, to reach this “effective” limit is unknown, but it likely does not require complete burial of all LWD elements. A conceptual comparison can be drawn with sand fence research that has shown a significant loss of trapping function when sediment reaches 80% of the fence height (e.g., Hotta & Horikawa, ).…”

The Role of Large Woody Debris in Beach‐Dune Interaction

Coastal foredune evolution involves complex processes and controls that result from the interaction of aeolian and nearshore dynamics. No studies to date have quantified and examined the role of large woody debris (LWD) as a modulator of sediment delivery across the backshore and as a control on foredune development and maintenance. Results from a 4‐year research initiative on a high‐energy, macrotidal beach, and foredune system show that storm events lead to wave‐induced erosion of the backshore and consequent reworking of the LWD matrix. The exposed LWD matrix subsequently traps wind‐blown sand on the upper beach, reducing sediment delivery to the foredune by 99% in some cases. In turn, deposition within the LWD matrix leads to rapid burial of the LWD, at least until the next reworking or dune erosion event occurs. Interannual observations at this site indicate that infilling of the accommodation space within the LWD matrix can be rapid, so sediment starvation of the foredune is typically a relatively short‐lived phase. This suggests that that the LWD matrix is a highly effective, yet ephemeral, sand‐trapping reservoir. Critical to these interactions is the frequency and magnitude of nearshore events that erode the beach periodically and reorganize the LWD matrix, which directly impacts the ability of LWD to modulate onshore sand transport to the foredune, store sediment in the backshore, and act as a buffer against erosive events. An empirically derived conceptual model explaining these relationships is presented.

Sand fences made of punched steel plate (PSP) have recently been applied to control wind-blown sand in desertified and Gobi areas due to their strong wind resistance and convenient in situ construction. However, few studies have assessed the protective effect of PSP sand fences, especially through field observations. This study analyzes the effects of double-row PSP sand fences on wind and sand resistance using field observations and a computational fluid dynamics (CFD) numerical simulation. The results of field observations showed that the average windproof efficiencies of the first-row and second-row sand fences were 79.8% and 70.8%, respectively. Moreover, the average windproof efficiencies of the numerical simulation behind the first-row and second-row sand fences were 89.8% and 81.1%, respectively. The sand-resistance efficiency of the double-row PSP sand fences was 65.4%. Sand deposition occurred close to the first-row sand fence; however, there was relatively little sand on the leeward side of the second-row sand fence. The length of sand accumulation near PSP sand fences obtained by numerical simulation was basically consistent with that through field observations, indicating that field observations combined with numerical simulation can provide insight into the complex wind-blown sand field over PSP sand fences. This study indicates that the protection efficiency of the double-row PSP sand fences is sufficient for effective control of sand hazards associated with extremely strong wind in the Gobi areas. The output of this work is expected to improve the future application of PSP sand fences.
