ABSTRACT- Over the past 50 years, oil mulching has been a common technique for sand dune stabilization in the southwest of Iran (Khuzestan province). However, concerns over the release of heavy metals from oil mulching have led to the search for alternative mulches that are capable of stabilizing sand dunes without environmental hazards. This study investigates the feasibility of using sugarcan...

the most usual type of petroleum mulch, which has been successfully used to combat desertification in large areain iran for more than thirty years, is produced by heavy residue petroleum cuts. the petroleum mulch consists of awide range of different heavy hydrocarbons such as polycyclic aromatic hydrocarbons (pahs). pahs are present atlow level in petroleum mulch, where there is contact with wa...

Coastal sand dunes have attracted the attention of plant ecologists for over a century, but they have largely relied on correlations to explain dune plant community organization. We examined long-standing hypotheses experimentally that sand binding, inter-specific interactions, abiotic factors and seedling recruitment are drivers of sand dune plant community structure in Sardinia, Italy. Removi...

Avalanches of various sizes occur due to instability during sand dune dynamics. A physically viable equation to model sand dune dynamics is a first order nonlinear difference equation. To visualize the size distribution of avalanches, sand dune dynamics has been numerically simulated by changing the strength of nonlinearity parameter (λ) that shows different impacts on dune dynamics. An equatio...

mulching is one of the methods of sand movement control to prepare condition for permanent fixation. oil mulches have been used in iran. because of high cost and negative environmental impacts of oil mulches, changes in mulches type and mulching methods is vital. therefore, for the first time in iran, different combinations of cement and lime were examined as stabilizer. sandy soil from the yaz...

New evidence indicates that sand availability does not only control dune type but also the underlying dune growth mechanism and the subsequent dune orientation. Here we numerically investigate the development of bedforms in bidirectional wind regimes for two different conditions of sand availability: an erodible sand bed or a localized sand source on a non-erodible ground. These two conditions ...
