Structural geomorphological landforms arise due to geological processes in tectonic regions. This study aims to identify the geomorphological landforms resulting from these processes in Wadi Wasit in the Sinai Peninsula in Egypt. The study depends on geological and topographic maps, aerial images, DEM (SRTM), fieldwork, and Global climate databases (POWER, ERA5). It used the GIS technique. The results showed that the surface rocks in the study area were deposited in the Upper Cretaceous, Paleocene, Eocene, Miocene, Pleistocene, and Holocene. The rocks consist of Limestone, Sandstone, Wadi deposits, Alluvial Hamadah deposits, and Fanglomerate. It was affected by 41 faults and a concave fold. These tectonic processes formed geomorphological landforms in the study area, which are: Fault scarps, Cuesta scarps, Structural Basins, Faulted Wadies, and Gorges.

Jeddah est la plus grande ville côtière du royaume et abrite le premier port de la mer Rouge, représentant la porte d’entrée des pèlerins pour rejoindre la Mecque. Cette cité historique, coincée entre la mer Rouge à l’ouest et la zone montagneuse du Hedjaz à l’est, est la deuxième ville d’Arabie Saoudite en termes d’extension spatiale et de population, après la capitale Riyad. Elle a connu une croissance urbaine sans précèdent, lors des décennies 70 et 80, qui s’est traduite par une littoralisation intensive. Cette étude se focalise sur cette pression anthropique continue sur la zone côtière .Une approche de suivi spatiotemporel de l’extension urbaine sur la mer, par l’utilisation des Systèmes d’information géographique (SIG) et des données de télédétection multisources a été adoptée. Les superficies des remblaiements successifs ont été cartographiées pour différentes périodes de 1965 à 2020. Les diverses affectations dont elles ont fait l’objet sont analysées, ainsi que changements morphologiques et environnementaux qu’elles entrainent. Les résultats montrent que la surface totale des terrepleins sur la période d’observation atteint environ 33 km (0,59 km /an en moyenne) dont 24,5 km entre 1972 et 1986, période de boom économique où Jeddah a enregistré sa plus grande expansion urbaine. Lors des diverses phases de la période d’étude, le port de Jeddah a gagné environ 11,8 km de superficie sur la mer, soit 94,4% de la zone industrialo-portuaire actuelle. Ainsi ce sont des zones maritimes, des récifs coraliens et d’ilots qui ont été transformées en terrains urbanisés dont les utilisations sont variées ; installations portuaires (36,1%), gouvernementale (21,5%), service Public (16.4), récréative/touristique (15,2%), ou résidentielle et commerciale (10,8%). Ces mutations impliquent à leur tour un bouleversement de l’environnement marin côtier ; création de lagunes semi-fermées et d’ilots artificiels, disparition de récifs coralliens, d’ilots et une modification de la morphologie de cette zone côtière.

Ras Baroud pluton is one of the well exposed granitic batholiths in the Central Eastern Desert of Egypt. The granites occure as isolated plutons of high relief circular and semicircular outlines. They are cut by zoned pegmatites and dikes of different types. The pegmatites are found as lenticular pockets and sheet-like bodies along the southern periphery of Ras Baroud pluton. The zonal sequence of the pegmatites is formed of an outer blocky feldspar zone. The intermediate mica zone (muscovite and/or biotite) and an inner zone of massive quartz might present in some pockets and absent in others. In some pegmatite pockets, the intermediate zone of mica occurs with some distinct dark alteration parts that record the highest radioactivity levels. The geochemical studies revealed that these pegmatites are attributed to low temperature late differentiated magmatic fluids enriched in volatiles. Field radiometric survey was used to evaluate the suitability of mineral resources at the different pegmatite zones to industrial use. The environmental radioactive parameters showed that the radioactivity of all four zones of the pegmatites is higher than the safety limit which indicate hazardous effects on human lives if used as indore building and/or ornamental stones. Also, the uranium migration rates and directions showed that uranium migrates from the radioactive altered zone which has the higher uranium content towards the other three pegmatite zones (outer, intermediate and inner zones). From a paragenetic point of view, zones in pegmatite are developed from the wall inward within a restricted pegmatitic stage. In the early stage, zoned pegmatites of simple mineralogy are produced. In the later stage, residual fluids rich in soda, silica, alumina and significant quantities of Nb, Ta, U, Th and F travel along fractures, react with the previously formed pegmatitic minerals forming new minerals of replacement origin. The zoned pegmatites host U-minerals (betafite and kasolite) as well as NbTa mineral (columbite) as invisible disseminations in the intermediate alteration zone, that confines their formation in a temperature range between 300 and 500C. The hydrothermal activity and the alteration processes are responsible for the deposition of the uranium minerals.

This paper aims to study the development of morbidity, recovery and fatality rates in Egypt during the period from February 2020 to the first of August 2020 and compare them worldwide. And answers a number of questions, including: Are the rates of infection and recovery for Corona disease in Egypt commensurate with those in the world?. Are the fatality rates in Egypt commensurate with global rates? What is the pattern of the Corona virus disease morbidity, recovery and death curve, in Egypt and the world? Based on the above, is it possible to predict the future of Corona in Egypt and the world ? The incidence of the disease in the world increased logarithmically from 0.7 per 100,000 people on February 14, reach to 166 per 100,000 on July 10, 2020, and by comparing this rate for Egypt, the rate was 0.09 per 100,000 in 13 March, rising to 80.2 per 100,000 people on July 10, 2020. Recovery rates in the world during the same period increased from 12.1% of the number of infected to 58.3% on July 10, 2020, while in Egypt, recovery rates it is half of the global percentage. The percentage of Fatality rates increased from 2.7% in the world, to 4.5% on July 10, 2020 , while the percentage in Egypt is close to it in the world Morbidity and fatality rates of the Corona epidemic, although they tend to gradually decrease in Egypt and the world,also increase the recovery rate , except that the fluctuation of cases of infection and death due to disease from day to day makes it’s difficult to predict the future of the disease in the time of ambiguity surrounding it on the one hand, and the absence of a vaccine that helps protect against the disease on the other hand.

Jurash is located in the governorate of Ahad Rufaida, 15 km south of Khamis Mushait, which is part of Asir region in the southwest of Saudi Arabia. The site contains the remains of large buildings, some of them are of stone and some of clay, and dates back to the pre-Islamic period and successive Islamic periods that indicate the human settlement in the city. Where the city of Jurash is located on the trade route and the next pilgrimage from Yemen, and thus became an important commercial center at that time. Hence, the importance of the study in redrawing the maps of the city and working on an ecological perception that highlights the urban development and the old environmental conditions and determining the archaeological value of the city of Jurash because of its geographical (natural / human) and tourism investment. This will enable the orienting of the future course of the city and the appreciation of its heritage as well as the study of the archaeological and archaeological value of Jurash and its possibility of being included in the list of World Heritage sites. This will also enable obtaining physical evidence to prove the heritage value and tourism importance of the city and its economic role in achieving the Kingdom of Saudi Arabia Vision 2030. Pedostratigraphy applied to urban archaeological sites, combined with geomorphological and archaeological data, provide important information for interpreting the complexity of urban geoarchaeology areas and their environment. This paper applies this methodology in the case of Jurash city and presents geomorphological and geoarchaeological data (stratigraphy, physicochemical soil properties, radiocarbon dating and pottery) for the study area where these remains are located. Geoarchaeological work is essential in archaeological excavations of urban areas, as demonstrated at Jarash where the study of pedostratigraphy provides crucial information on past environmental changes and human activities. Pedostratigraphic records and archaeological remains should be considered part of the geological and cultural heritage of urban areas.
