“…On the Egyptian side, dunes in most of the erg are unvegetated and fully active (Figs. 3 and 4), so much so that they have been considered a hazard to farmland, roads, and infrastructure (Misak and Draz, 1997). Although interdune areas are often vegetated, the crests and sides of dunes in Sinai host little or no vegetation.…”

"Origin of the Sinai-Negev erg, Egypt and Israel: mineralogical and geochemical evidence for the importance of the Nile and sea level history" (2013 Overall, the mineralogical data suggest that the dunes are derived dominantly from the Nile Delta, with Sinai wadi sands being a minor contributor. Geochemical data that proxy for both the light mineral fraction (SiO 2 /10eAl 2 O 3 þ Na 2 O þ K 2 OeCaO) and heavy mineral fraction (Fe 2 O 3 eMgOeTiO 2 ) also indicate a dominant Nile Delta source for the dunes. Thus, we report here the first empirical evidence that the SinaieNegev dunes are derived dominantly from the Nile Delta. Linkage of the SinaieNegev erg to the Nile Delta as a source is consistent with the distribution of OSL ages of Negev dunes in recent studies. Stratigraphic studies show that during the Last Glacial period, when dune incursions in the SinaieNegev erg began, what is now the Nile Delta area was characterized by a broad, sandy, minimally vegetated plain, with seasonally dry anastomosing channels. Such conditions were ideal for providing a ready source of sand for aeolian transport under what were probably much stronger glacial-age winds.With the post-glacial rise in sea level, the Nile River began to aggrade. Post-glacial sedimentation has been dominated by fine-grained silts and clays. Thus, sea level, along with favorable climatic conditions, emerges as a major influence on the timing of dune activity in the SinaieNegev erg, through its control on the supply of sand from the Nile Delta. The mineralogy of the SinaieNegev dunes is also consistent with a proposed hypothesis that these sediments are an important source of loess in Israel.Published by Elsevier Ltd.

“…The inhospitable terrain and political instability [42] hinders access. Moreover, sand drift and dune migration affecting much of North Sinai can rapidly bury modern structures [28,47] or ancient sites that may have been excavated in the past [46]. The use of long wavelength (L-band) spaceborne SAR could be a promising tool for regular survey of large areas for man-made structures.…”

“…Sand drift and dune migration affect much of North Sinai. The burial of modern infrastructure is a common and serious problem [28,47]. The use of spaceborne SAR to regularly survey large areas could potentially constitute a cost-effective technique, and given the transmissivity of dry sand to microwave wavelengths, may uniquely provide information on structures obscured by sand.…”

“…Careful comparison of the extracted features that are not present on any of the considered WMS layers with the available optical imagery reveals in many cases the presence of partially buried unpaved roads (e.g., Figure 7f). Sand drift and dune migration covering infrastructure is a common problem throughout the region, e.g., [28,47]. Dune migration has been studied and quantified in this area recently by Hermas, Leprince and El-Magd [28], who detected lateral movements along the crest lines of linear dunes of up to 20 m per year.…”

Abstract:Techniques were implemented to extract anthropogenic features in the desert region of North Sinai using data from the first-and second-generation Phased Array type L-band Synthetic Aperture Radar (PALSAR-1 and 2). To obtain a synoptic view over the study area, a mosaic of average, multitemporal (De Grandi) filtered PALSAR-1 σ • backscatter of North Sinai was produced. Two subset regions were selected for further analysis. The first included an area of abundant linear features of high relative backscatter in a strategic, but sparsely developed area between the Wadi Tumilat and Gebel Maghara. The second included an area of low backscatter anomaly features in a coastal sabkha around the archaeological sites of Tell el-Farama, Tell el-Mahzan, and Tell el-Kanais. Over the subset region between the Wadi Tumilat and Gebel Maghara, algorithms were developed to extract linear features and convert them to vector format to facilitate interpretation. The algorithms were based on mathematical morphology, but to distinguish apparent man-made features from sand dune ridges, several techniques were applied. The first technique took as input the average σ • backscatter and used a Digital Elevation Model (DEM) derived Local Incidence Angle (LAI) mask to exclude sand dune ridges. The second technique, which proved more effective, used the average interferometric coherence as input. Extracted features were compared with other available information layers and in some cases revealed partially buried roads. Over the coastal subset region a time series of PALSAR-2 spotlight data were processed. The coefficient of variation (CoV) of De Grandi filtered imagery clearly revealed anomaly features of low CoV. These were compared with the results of an archaeological field walking survey carried out previously. The features generally correspond with isolated areas identified in the field survey as having a higher density of archaeological finds, and interpreted as possible islands of dry land, which may have been surrounded by lagoons, rivers, and swamplands in antiquity. It is suggested that these surrounding areas may still have a higher water content, sufficient to be detected in processed Synthetic Aperture Radar (SAR) imagery.

Aim of survey research on the type of Gumuk Pasir Tropik (Tropical Sand Dunes) is intended to reveal species diversity, a system of knowledge that includes the use, knowledge and fulfilment of its various needs. The survey was conducted to document plant diversity, supporting the greenbelt construction of the NYIA airport to take its documentation and sustainable development. The location of the research was conducted at NYIA Airport in Glagah village, Temon district, Kulon Progo regency, Yogyakarta Province Indonesia. The research was conducted using structural and open ended interview, direct observation and survey. Local people have a good knowledge of the diversity of plant species. However, lack of wisdom in the management resulted in natural forest sand dune ecological damage. The survey of local people in Glagah village resulted in identification of 84 plants that are presented in the paper.
