“…In addition, the broad heterogeneity of the Arabian landscape and the spatio-temporal variability of climate systems are becoming increasingly apparent. Regional complexity governed by localised geological and climatic factors is also considered a key component in understanding the history of regional climate change [62] and, by extension, human occupation.…”

“…14 C ages in the database have been calibrated using the latest IntCal20 and Ma-rine20 calibration curves [76]. The database includes two inputs from the SCAPE database, a database on the chronological robustness of Holocene Quaternary palaeoenvironmental sites in Southeast Arabia [62]. The landform type classification has been developed to distinguish common types of geomorphological, sedimentological, and biological characteristics of Quaternary palaeoenvironmental sites for a nuanced analysis of their climatic implications.…”

“…The endangerment level of each site was evaluated based on a visual assessment of historic and current satellite imagery on Google Earth Pro and Bing Maps. These platforms were used because they provide free high-resolution colour imagery of the past 20 years [77], the period in which most palaeoenvironmental studies have been conducted in this region [62].…”

Quaternary palaeoenvironmental (QP) sites in Southeast Arabia are important not only to understand the history of global climate change but also to study how ancient humans adapted to a changing natural environment. These sites, however, are currently missing from conservation frameworks despite reports of destroyed sites and sites under imminent threat. This study presents the Geocultural Database of Southeast Arabia, the first open-access database on QP sites in this region, created as a comprehensive inventory of regional QP sites and a tool to analyse QP records and archaeological records. The endangerment assessment of QP sites in this database reveals that 13% of QP sites have already been destroyed and 15% of them are under imminent threat of destruction, primarily due to urban development and infrastructure development. Chronological and spatial analyses of QP and archaeological sites and records highlight the intricate relationship between palaeoenvironment and archaeology and emphasise the need for sub-regional-scale studies to understand the variation of climatic conditions within the region, especially to study changes in the ancient human demography. This database illustrates the potential of a geocultural approach that combines archaeological heritage with Quaternary geoheritage as a way forward for the conservation of QP sites at risk.

“…In Saudi Arabia, there are numerous shallow aquifers at various depths. Among these aquifers, there are buried water channels, with high porosity and permaebility, which have been formed since Mid-Late Quaternary (Pleistocene) and controlled by ancient climate and environmental changes in the Arabia Peninsula (Woor et al, 2022). These changes resulted in topographic rippling (i.e., wavy terrain surface) and abrupt changes in terrain slopping (i.e., inclined terrain surface).…”

Al Saud (2023) worked on detailed cartography for all drainage systems of Saudi Arabia using SRTM DEM and topographic maps. However, a number of watercourses were noted with anomalous morphometric and sedimentological characteristics . This includes abrupt termination of stream networks, traces for dry channels and presence of linear saline soil horizons. This was attributed to the existence of paleodrainages which have been noted in several studies in the Arabian Peninsula including Saudi Arabia, and they were attributed to large global climate fluctuations that were reflected in topographic rippling and abrupt changes in terrain slopping, acting on the extinction of many watercourses and creation of others. This study characterizes paleodrainages in Saudi Arabia using remote sensing products. In this respect, SRTM DEM was used to generate detailed drainage systems; while Advanced Land Observing Satellite (ALOS) Phased Array Type L-band Synthetic Aperture Radar (PALSAR) and Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) were processed to detect paleodrainages and the relevant paleo-geomorphological features using a number of digital techniques. Seven aspects of these channels were identified and all indicating the presence of alluvial sedimentation with high porous and permeable linear features which are potential to store and transmit groundwater. They can be also routs for paleodrianagesthe intrusion of saline water on-land. The identified paleodrainages can be potential groundwater aquifers, suitable sites for groundwater artificial recharge especially where saltwater is intruded along these drainages.

Al Saud (2023) worked on detailed cartography for all drainage systems of Saudi Arabia using SRTM DEM and topographic maps. However, a number of watercourses were noted with anomalous morphometric behavior. This includes abrupt termination of stream networks, traces for dry channels and presence of linear wet and saline soil horizons. This was attributed to the existence of paleochannels which have been noted in several studies in the Arabian Peninsula including Saudi Arabia. The history of these channels was returned to Late Quaternary (Pleistocene) epoch when large global climate fluctuations occurred, and these changes were reflected in topographic rippling and abrupt changes in terrain slopping, which in turn acted on the extinction of many watercourses and creation of others. This study aims at characterizing several observations for paleochannels in Saudi Arabia using remote sensing products. In this respect, Shuttle Radar Topography Mission (SRTM) was used to generate detailed drainage systems; while Advanced Land Observing Satellite (ALOS) Phased Array Type L-band Synthetic Aperture Radar (PALSAR) and Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) were processed to detect paleochannels and the relevant paleo-geomorphological features by adopting a number of digital techniques. Several aspects of these channels were identified. The significance of paleochannels includes the high potentiality for groundwater storage, and interprets the geographic extent of saline water on-land.
