Abstract:

This special issue of Historical Records of Australian Science explores some of the sciences that have contributed to our understanding of inland Australia, country variously known as desert, the arid zone, drylands and the outback. The sciences that have concentrated on deserts include ecology, geomorphology, hydrology, rangeland management, geography, surveying, meteorology and geology, plus many others. In recognition that desert science has surged ahead in the past few decades, we have invited contributors who describe various different desert initiatives. We use these case studies to open up the discussion about how Australians see their desert lands, how this has changed over time and how desert scientists from the rest of the world regard the distinctive desert country in Australia.

Abstract:

Geomorphic research in arid environments continues to attract a wide variety of researchers who employ a range of techniques to understand modem processes and landscape evolution in dry lands. A notable feature of much contemporary research is the collaboration between geomorphologists and those with specialized geochemical and geophysical knowledge, for example in the areas of exposure-age dating. Another significant development is the synergism (at least in the western USA) between environ mental and public policy concerns and fundamental geomorphic research. For example, the need to understand landform development and the history of climate in the region of the proposed high-level nuclear-waste storage facility at Yucca Mountain in southern Nevada has generated important fundamental research on soil-forming processes (Reheis et al., 1995), soil-landscape relations (Peterson et al., 1995), slope stability (Whitney and Harrington, 1993) and evidence for past groundwater discharge conditions (Quade et al., 1995). Similarly, concerns about the response of sensitive semi-arid areas to possible future climate change has stimulated research into the Holocene climatic history and aeolian environments of the Great Plains (Muhs and Maat, 1993; Forman et al., 1995; Loope et al., 1995; Madole, 1995; Muhs and Holliday, 1995; Wolfe et al., 1995) and the Negev Desert (Tsoar, 1995). Of particular importance is the realization that droughts and changes in sediment supply from fluvial systems within the past 150 yr have had effects on dune mobility that are comparable to some inferred Holocene climate changes (Muhs and Holliday, 1995).

Abstract:

AbstractIn the desert environment of south-west Jordan thick sequences of continental sandstones of Cambrian-Ordovician age support spectacular scenery, comparable with that of the Colorado Plateau of south-west USA or the central Sahara and similar in many aspects to the Danxia landform of southern China. Dissection of a sandstone tableland has given rise to numerous inselbergs and large mesas, rising from the sand-covered desert floor. The height of the hills varies from a few tens to 500-700 m in the Wadi Rum area, whereas their slope shapes are controlled by lithological properties of particular sandstone units. Rock walls of the sandstone inselbergs are subject to frequent rock falls and rock slides and host an impressive array of tafoni and honeycombs due to selective weathering, as well as a number of rock arches. Lithological differences within the sandstone sequence are crucial controls on the shape and evolution of rock slopes, exerting the influence via contrasting patterns of weathering and slope failures. The presence of ferruginous layers in the Umm ‘Ishrin Sandstone is of major importance and explains the fundamental morphological differences between the otherwise similar Umm ‘Ishrin and Disi sandstone units

Full text

Abstract:

Dust storms originate in many of the world's drylands and frequently present hazards to human society, both within the drylands themselves but also outside drylands due to long-range transport of aeolian sediments. Desert dust hazards can occur where dust is entrained, during the transport phase, and on deposition. This paper draws on studies in physical geography, medical geology and geomorphology to discuss case studies of accelerated soil erosion, the health effects of air pollution caused by desert aerosols, injuries related to transport accidents caused by poor visibility during desert dust events, the spread of disease, and problems with water supplies and at solar power plants caused by dust deposition.

AbstractThis paper considers some of the general issues relating to the history of exploration in the Libyan (Western) Desert. These issues are: why there have been remarkably few books on desert exploration; the despised role of the motor car which was so important in the exploration of the Libyan Desert; the longevity of some explorers, the prominent role of women in Islamic travels; the great deal of time – sometimes years – that some of the explorers spent in the field; the role of indigenous people; the parts played by professionals, and amateurs; the undertaking of scientific work of high quality, not least in the field of geomorphology; and the international nature of exploration.

Abstract:

Repeated freeze–thaw cycles on slopes trigger sorting and solifluction mass movements, while subsequent displacement of material modifies the geomorphology of slopes as well as permafrost dynamics. This study focuses on the geomorphology and the cryostratigraphy of a polar desert stone-banked solifluction lobe with the objective to clarify the impact of slow mass movements on ground ice aggradation. The morphology of the solifluction lobe was characterized by peripheral ridges of coarse gravel, partially surrounding a depression filled with finer sediments saturated with water and covered by organics. Cryostratigraphic analysis demonstrated that the solifluction lobe’s formation led to the development of a syngenetic layer of permafrost with an ice content that varied according to the location in the lobe. The ice-rich cryofacies formed in the central depression of the lobe should act as a buffer to potential active layer deepening, slowing down its thawing, whereas the ice-poor cryofacies formed under the ridges is expected to thaw faster than the central depression under climate warming scenarios. Thawing of the ice-rich zone in the future will result in differential thaw subsidence between the ridges and the central depression of solifluction lobes, along with increased drainage through the ridges and subsequent changes in hydrology.

Abstract:

Abstract South African geology, geomorphology and climate are distinctly variable, resulting in a complex hydrological cycle superimposed on equally complex ground conditions. With fractured and karstic systems dominating the hydrogeology, thick vadose zones comprising soil and rock and at highly variable moisture conditions contribute to complex hydrostratigraphic systems comprising various confining and hydraulically connected units. This paper proposed standard terminology for basic concepts pertaining to the description of ground and water in the subsurface to eventually propose a hydrostratigraphic classification based on abiotic factors fairly constant over short periods of time (geology, geomorphology and climate), as well as those temporally highly variable (climate) and those introduced by human involvement (society). Ten major hydrostratigraphic units are eventually described, namely the Cape Fold Belt, Kalahari Desert, Witwatersrand Supergroup, Malmani Subgroup, Cenozoic Coastal Deposits, Saldanian Basement, Karoo Main Basin, Namaqua-Natal Metamorphics, Waterberg Group, and Archaean Granitoids.

Abstract:

Vegetation cover is fundamental in the formation and maintenance of geomorphological features in dune systems. In arid Australia, increased woody shrub cover has been linked to removal of the apex predator (Dingoes, Canis dingo ) via subsequent trophic cascades. We ask whether this increase in shrubs can be linked to altered physical characteristics of the dunes. We used drone-based remote sensing to measure shrub density and construct three-dimensional models of dune morphology. Dunes had significantly different physical characteristics either side of the ‘dingo-proof fence’, inside which dingoes are systematically eradicated and shrub density is higher over vast spatial extents. Generalized additive models revealed that dunes with increased shrub density were higher, differently shaped and more variable in height profile. We propose that low shrub density induces aeolian and sedimentary processes that result in greater surface erosion and sediment transport, whereas high shrub density promotes dune stability. We speculate that increased vegetation cover acts to push dunes towards an alternate stable state, where climatic variation no longer has a significant effect on their morphodynamic state within the bi-stable state model. Our study provides evidence that anthropogenically induced trophic cascades can indirectly lead to large-scale changes in landscape geomorphology.

Abstract:

The Glacial Geomorphological Map (1:200 000) of Mt, Tomur Region, Tianshan, covers 78°33′ – 81°10′E and 41° 08′ – 42° 44′N, with high mountains, deep valleys and many snow peaks, the highest being Mt. Tomur (7435.3 a.s.l.). There are many glaciers in this region with a total area of 4553.69 km2. The melt water from glaciers irrigates the large oasis of Aksu, in the piedmont region in southern Xingjiang and waters the valley plain of Teks River in the Yili area. From piedmont plain to highest mountain summit, the vertical zonality of geomorphology is quite clear, rich in various geomorphological types, representing alpine geomorphology of the arid desert in Central Asia. The author joined the glacial/geomorphological expedition to the Mt. Tomur Region in 1963, 1973 and 1974, and, in the process of mapping, cooperated closely with mapping engineers. This involved extensive use of aerial photographs, satellite images, large-scale topographic maps, geological maps, geomorphological maps and other data, and comprehensive analyses, comparisons, and judgements of data. Special emphasis was placed on existing glaciers and the geomorphology of Quaternary glaciers, according to form, composition and relative chronological periods. The geomorphology was divided into five great systems, i.e. glacial, fluvio-glacial, fluvial, arid and artificial. Twenty-four geomorphic types were defined as the basic elements of the geomorphological map and shown in different colours and by various marks, while old and Neozoic faults were shown by black line marks. There are representative heights on all geomorphological zones. Colour brush-shading added much to the stereo effect. Below the main map, the longitudinal and cross sections of Quaternary geology and geomorphology of the Tialan valley, the stratigraphical columnar profile of West Zamtia and the fluvial/lacustrine deposit profile of the Loska basin were attached, showing the stratigraphical relation between the glacial and non-glacial deposit and the basis for the divisions of the glacial and inter-glacial periods.

Abstract:

Nowadays, desertification is a common major environmental problem confronted by human society. Analysis in dynamic change of desertification is one of the tasks to control it, and the interpretation of desertification data is the base to analyze the dynamic change. Based on the analysis of collected data of geology, geomorphology, soil, climate, hydrology, and vegetation, the author indicates that different periods of desertification degree distribution maps can be obtained by selecting multi temporal TM images of the study area in recent years, which are interpreted by the tool of RS & GIS. Then, Kubuqi desert is researched as a sample and desertification dynamic change is discussed in terms of desertification area changes, spatial changes of desertification levels. The main ideas can be deduced as follows: 1. The results indicate that frequent human activities will speed up the degradation and deterioration of ecosystem in Kubuqi desert where environmental capacity is small. 2. In addition to general engineering and biological measures, tourism development should be taken into consideration to eliminate the root causes of irrational human activities and keep dynamic balance of ecological systems and human environment.

Abstract:

Prehistoric rock drawings of large boats in wadis of the central Eastern Desert, Egypt, divided their investigators into two main groups with quite different views about their origins and cultural affiliation. One of the groups (P. Červiček et al.) insisted on ‘religious’ (cultic, magic, etc.) nature of these petroglyphs attributing them to local traditions but actually tearing away from the reality, primarily on the ground that boats could have never come to be in the desert many tens of kilometers from both the Nile and the Red Sea. Another one, following ideas of W. M. Flinders Petrie, interpreted these boat images as ships of a ‘Dynastic Race’ of oversea invaders who conquered Egypt and consolidated her under their power. This hypothesis, once disapproved by most of archaeologists and Egyptologists, has recently acquired many new adherents; it assumes, in particular, the most real rivers to have flown at the time of the earliest boat petroglyphs (5th to 4th Millennia B.C.) along Wadi Hammamat and Wadi Barramiya, where short routes pass from the Red Sea coast to the Nile. Even rejecting Petrie’s ‘diffusionistic’ version on the whole, one cannot ignore the palaeogeographical fact that the climate of Predynastic Egypt was moist, characterized by monsoon rains which, in combination with geomorphology of the Eastern Desert, could only have favoured here in the period under consideration the formation of regular tributaries of the Nile.

Abstract:

A systematic study of the wind regime characteristics in a region can not only accurately grasp the dynamic factors of the development of aeolian geomorphology, but also provide a scientific basis for the prevention and treatment of regional sand disasters. Taking the Hobq Desert as the study area, the basic characteristics of dune are analyzed by using remote sensing images. Based on the annual meteorological data of six meteorological stations from 2009 to 2018, the spatial and temporal distribution characteristics of wind speed were obtained. With the daily wind data of three stations from 2009 to 2018, we have figured out the wind regime and sand transport characteristics of the Hobq Desert. The results show that the sand dune height of the Hobq Desert ranges large, the highest height is 5010 m and the lowest is 10 m. It decreases gradually from the west to the east. The height of dune mainly distributed below 1500 m, followed by 1500–2000 m. Migratory sand dunes in Hobq Desert accounts for 51.8% and is mainly distributed in the west of the desert. The distribution area of fixation sand dunes in Hobq Desert is the least, accounting for 8.3%. The migratory dune pattern is trellis dune, semimigrated dune and semifixed dune patterns include honeycomb dune, parabolic duneand brush dune, and fixation dune pattern is grass dune. Annual wind speed was greatest in the southeast and decreased moving to the northwest. The dominant wind direction was W and SW from 2009 to 2018 in the Hobq Desert, the average wind speed of the prevailing winds mainly distributed at 4–8 m/s. The frequency of wind speed exceeding 10 m/s is very low, with a maximum value of 10% or below. There is a low energy wind environment in the Hobq Desert, with intermediate annual directional variability and obtuse or acute bimodal wind regime. The resultant drift direction (RDD)at Dongsheng station was relatively constant from 2009 to 2018, it was about 350°. RDD differed significantly at Baotou and Linhestations were 181 ± 169° and 231 ± 121°, respectively.The relationship between drift potential (DP) and the average and maximum wind speed was expressed as a power function. DP was strongly correlated with them. There is no significant correlated between the temporal changes in DPandprecipitation and temperature from 2009 to 2018 in the Hobq Desert.

Abstract:

On examining the scientific literature of recent years, one notices an increase in the number of studies of global warming and its impact on the Earth’s various environments. Research has been undertaken in various fields such as geomorphology, hydrology and many others. In the context of climatic change, there is growing interest in the study of past floods, or palaeofloods. Researchers are attempting to reconstitute the chronology of past floods, especially with respect to past or subrecent climatic changes. The work involves using different methodological approaches borrowed from various disciplines including geology, geomorphology and ecology. The reconstruction of ancient hydrological events such as palaeofloods in fact requires that different methods and techniques be combined in order to trace the chronology of events as precisely as possible using different biophysical parameters. A wide variety of indicators are used in the chronological reconstruction of ancient fluvial environments, whether in humid, subhumid or desert regions. These indicators involve analysing stratigraphic sequences and sedimentary deposits, organic matter and macrorest deposits, as well as using radiocarbon dating(14C), thermoluminescence (TL), and dendrochronology and lichenometry. In fact, most work on the reconstitution of the frequency and magnitude of ancient floods uses several methods and techniques to obtain the long-term chronology of flood events in relation to the specific conditions (e.g., climate, geomorphology) of a region or study area. With the publication of several studies in palaeohydrology, it was interesting to examine, through a literature review, the various approaches used in the study of palaeofloods. This kind of study has seen major advances, which can be explained partly by the interest generated by global climate change and its effect on river-system dynamics.

Abstract:

Abstract The formation of the Kelso Dunes in the eastern Mojave Desert, California, was a landscape-changing event triggered by an increase in sediment supply that followed the incision of Afton Canyon by the Mojave River ca. 25 ka. Eastward migration of sand dunes occurred along a well-defined eolian transport corridor. Dunes temporarily blocked washes resulting in substantial aggradation of eolian and fluvial sediments. Stratigraphic exposures reveal numerous fining-up sequences with interbedded eolian sands that provide evidence of dune dams and subsequent aggradation. Luminescence ages reveal that dune blocking and aggradation correspond to a regional pulse of alluvial fan sedimentation that occurred ca. 14–9 ka. Meanwhile, relative landscape stability occurred downstream of dune dams, resulting in the formation of a moderately developed soil on abandoned fluvial deposits. The next pulse of alluvial fan activity ca. 6–3 ka likely resulted in the breaching of the dune dams, followed by incision. Eolian system sediment state theory suggests that eolian activity in the Mojave Desert is closely tied to enhanced sediment supply, primarily related to the Mojave River–Lake Mojave system. Our data suggests that Intermittent Lake Mojave I, ca. 26–22 ka, triggered a large dune-building event that impounded massive amounts of sediment derived from alluvial fans deposited during the Pleistocene-Holocene transition. Breaching of dune dams and sediment recycling may have also increased sediment supply that contributed to late Holocene eolian activity. This profound impact on the regional geomorphology highlights the critical importance of eolian-fluvial interactions in desert environments.

Abstract:

AbstractThis paper describes the Quaternary geology of the area around Gasr Banat which lies near the confluence of the Wadis N'f'd and N'fed in the pre-desert of Tripolitania. The site is of interest because of its aridity, the notable archaeological remains that occur in the region and the opportunity it offered to map the surficial deposits of an area otherwise largely unknown. The survey revealed that two Pleistocene cobble and gravel units laid down by ‘torrential’ rivers could be distinguished: the older of which had been cemented by calcrete. Polyphase slope deposits occur. Thin section studies of the calcrete suggests it is possible to recognise two arid and two humid episodes from its micromorphology.The Holocene period is represented by water-lain and aeolian deposits on the wadi floodplain, and climbing and barchan dunes on the adjacent hills. The period immediately prior to the construction of major cross wadi barrages may have been characterised by larger or more frequent floods than occurred immediately prior to the 1984 survey; the palaeoclimatic significance of this observation is unclear. One major barrage in the area is shown to have been built on substantial earth foundations. The assumed Romano-Libyan date of these barrages still remains to be proven, but, conversely, it is now demonstrated that they were not constructed or reconstructed in the 1950s.
