    ABSTRACT: Abstract Groundwater is a very important resource across Ismailia area as it is used in domestic, agricultural, and industrial purposes. This makes it absolutely necessary that the effects of land use change on groundwater resources are considered when making land use decisions. Careful monitoringof groundwater resource helps minimize the contamination of this resource. This study developed a GIS-based model to assess groundwater contamination in theWest Ismailia area based on its hydrochemical characteristics. The model incorporated five different factors which are standardized to a common evaluation scale. The produced factor maps include the depth to the water table, the potential recharge, the soil type, the topography, and the thickness of saturation. These maps are combined in ERDAS Imagine, ARC INFO, and ARC GIS software using geostatistics and a weighted overlay process to produce the final groundwater potential risk map. The model output is then used to determine the vulnerability of groundwater to contamination by domestic, agricultural, and industrial sources. The produced risk maps are then combined with the groundwater contamination potentiality map using an arithmetic overlay in order to identify areas which were vulnerable to contamination. The results of this study revealed that the groundwater is highly vulnerable to contamination that may result from the inappropriate application of agrichemicals and domestic and industrial activities. The produced integrated potential contamination maps are very useful tools for a decision maker concerned with groundwater protection and development. Keywords Geospatial . Geostatistics .

    ABSTRACT: With the development of economic activities in the world, the construction activities have also increased. A proper surface and subsurface investigation is made to assess the general suitability of the site and to prepare an adequate and economic safe design for the proposed work. The main purpose of the current study is to create a spatial model of the geotechnical conditions and considerations by using geographic information systems (GIS) techniques to develop and analyze a site model and to plan site activities at the new extension of Suez City (SC). In the geotechnical site evaluations, GIS can be used in four ways, data integration, data visualization and analysis, planning and summarizing site activities, and data presentation. The integrated data can be displayed; manipulated and analyzed using tools build into the GIS programs, thus creating the geotechnical site model of the study area. Decisions can be made for further site activities and the results of the site activities can be integrated into the GIS site model. Interpretation of geotechnical data frequently involves assimilating information from many sites each with a unique geographical location. Interpretation of these data requires the spatial location to incorporate into the analysis. Weights are assigned to different of mechanical, physical soil properties, geological, hydrogeological, and other ancillary data. Finally, the weighted maps are integrated using a GIS based on the construction purposes for the new extension of SC for significant cost savings in design, construction and longevity. The ideal and good zones’ highest regime has been observed towards central and western regions with sporadic pockets. The marginal zones to average zones are moderately suited for shallow foundation.

    ABSTRACT: The Sinai Peninsula constitutes an important district of the Egyptian lands where it forms a triangular portion in northeastern Egypt. The southern Sinai metamorphic complexes are the northern uppermost part of the Arabian–Nubian Shield revealing the upper and middle crust from the East African Orogeny, in which they tectonically evolved. The Feiran–Solaf metamorphic complex (FSMC) of Sinai, Egypt is one of the highest grades metamorphic complexes of a series of basement domes that trends NW and crops out throughout the Arabian–Nubian Shield. The main aim of the present study is to apply the geospatial technology and to represent the capability of the geospatial technology to estimate the combined influence of lithology and structure studies, and to construct the lithological and structural maps of FSMC. Furthermore, detailed structural analysis is carried out to reveal the different ductile and brittle deformational events and proposed the tectonic evolutionary model for the study area. Mainly geospatial technology and structural analysis software have been used to go well with the aim of the present study. Developing specific image processing of satellite images and structural analysis were succeeded to discriminate the various lithological rock units, and the geological structural features of the FSMC, using geographic information system tools to construct the different thematic maps, were extracted. The present detailed investigations of the enhanced satellite images, structural analysis, and field verification reveal that the FSMC reached its present tectonic setting through more than four deformational phases concluding that the Pan-African Najd Fault System continued in Sinai and was reactivated during Red Sea tectonics as indicated by the dextral shear zone (Rihba) bordering the northern side of the FSMC.

    ABSTRACT: Um Bogma area is the most famous mineralized locality in Sinai, Egypt. It is characterized by the presence of manganese, iron, and copper deposits. Apart from the mill tailings and spoil heaps, the results indicated the decrease of soil contamination downstream. As a result of random manganese mining activity in Um Bogma area, many hazardous elements such as iron, copper, manganese, lead, and zinc as well as many others associating heavy metals such as arsenic, selenium, and sulfur are dispersed in the environment. This study assesses and monitors the environmental impacts of such mining activities in the west central Sinai, using multitemporal spectral remote-sensing sensors (MSS 1972, TM 1986, and ETM+7 2000). The results have shown the very high potential of temporal imagery in mining-related contamination either directly through mineral and rock mapping of the mining waste and residues and related contaminated areas. تعتبر منطقة أم بجمة من أشهر مناطق التعدين بوسط غرب سيناء، مصر، حيث تتميز بوجود رواسب خامات المنجنيز، والحديد، والنحاس. ونتيجة وجود أكوام المخلفات التعدينية الناتجة عن النشاط التعدينى، فقد أشارت النتائج الدراسة إلى وجود تلوث بالتربة؛ نتيجة النشاط التعدينى العشوائى لخام المنجنيز بالإضافة إلى جود العديد من العناصر الخطرة بيئياً مثل الحديد، والنحاس، والمنجنيز،والرصاص، والزنك، وأيضا مصاحبتها للعديد من العناصر الثقيلة المشتتة بيئياً مثل الزرنيخ، والسلينيوم، والكبريت. هدفت الدراسة إلى عمل تقييم ورصد للتأثيرات البيئية الناتجة عن النشاط التعدينى بمنطقة غرب وسط سيناء، وذلك عن طريق معالجة وتحسين المجسات الطيفية للأستشعار عن بعد من خلال استخدام المرئيات الفضائية ذات الفترات الزمنية المتعاقبة كالمرئيات الفضائية للقمر الصناعى الأمريكى لاندسات، مثل مرئية الماسح المتعدد الأطياف سنة 1972، والمرئيات الفضائية المحسنة المسجلة لاندسات عامى 1986 و2000. وتوصلت الدراسة إلى أهمية استخدام المرئيات الفضائية المتعاقبة زمنياً فى رصد وتقييم ومتابعة التلوث البيئى، والذى له علاقة مباشرة بالنشاط التعدينى والتكوينات الصخورية بمنطقة الدراسة، وتم ذلك من خلال استنباط ورسم خرائط النفايات والمخلفات المعدنية وما يتصل بها من المناطق الملوثة.

    ABSTRACT: Ismailia Canal is the principle source of drinking water supply to Suez Canal and Sinai governorates. However, Ismailia Canal is endangered from unwise activities in the surrounding environment. Drinking water resources protection can be implemented using land-use monitoring system or through land-use controls based on hydrogeologic mapping to study the impacts of development on water quality. Our approach is to protect the direct and indirect catchment areas for surface water supply, especially the sensitive areas, those that are more vulnerable to contamination than other areas. Remote sensing and geographic information system techniques are applied to construct and integrate the hydrogeological data, inventory for potential sources of contamination and mapping the sensitive areas in order to construct the a protected buffer zone for Ismailia Canal, and to constrain the development activities in all the surrounding areas of surface water supply. The sensitive areas are delineated, where extra protection is required, based on soils properties, geology, and specific hydrogeological criteria. Industrial areas, drains, and septic tanks in the surrounding villages are the common potential sources of contamination. The hydrologic relation between Ismailia Canal and groundwater has great variations. Comprehensive plan for water protection were composed. It includes maintaining three natural protection zones of at least 300-m width along the main course of the Canal and delineating vulnerable zones depending on the aerial extension of the sensitive areas within 10 km on both sides of the Canal. Specific protection measures are recommended over the sensitive areas. The natural ecosystems of swamps around Ismailia Canal should be conserved and the processes of continuous burial prevented.

    ABSTRACT: Natural hazard analysis involves mapping and identifying future hazardous zones through the analysis of the controls influencing hazard initiation and occurrence. One of such natural hazard is the landslide. Landslides are amongst the most costly and damaging natural hazards especially in mountain regions and are triggered mainly by seismic activity and/or rainfall. The aim of the present study is to integrate Remote Sensing (RS) and Geographic Information System (GIS) tools to create thematic layers for assessment and the estimation of landslide hazard zones in and surrounding the Wadi Watier area, South Sinai, Egypt. Various factors, variables and/or parameters can be derived from thematic layers such as lithology, structural lineaments, land-cover/land-use, terrain analysis and earthquakes. Intensity risk layers were created by using ERDAS Imagine 9.2, ARC GIS 9.2 and ARC INFO 7.2.1 software. Enhanced Thematic Mapper (ETM+7) Landsat satellite images were used to discriminate and extract structural lineaments, lithology and land-use/land-cover variables for the study area. The Digital Elevation Model (DEM) was generated from digitized topographic maps to produce terrain analysis maps such as; slope, aspect, height elevation, and 3D. The weighting score rating system based on the relative importance of various causal factors derived from RS data and other thematic layers was used for landslide hazard zonation (LHZ). Based on these data, a simple algorithm was created to classify the area into different risk zones. By overlaying all hazard layers a final landslide hazard map was produced. Using trial and error and statistical methods the weight score rating values have been readjusted. GIS integration with RS data can greatly facilitate classifying landslide hazard zones into low risk, moderate risk and high risk by using a slicing operation. Seismic data are integrated with final the LHZ to generate a LHZ scenario map for the future and to draw up an action plan of mitigation measures to avoid the damage, loss of life and socio-economic impacts in the study area.

    ABSTRACT: Satellite remote sensing data, in addition to Geographic Information Systems (GIS), offers an excellent alternative to conventional mapping techniques in monitoring and mapping of geo-hazards areas. One of the most sustainable development projects in Egypt has been accomplished in Sinai, especially along and around the Gulf of Aqaba and the Gulf of Suez. Variations along the coastal zone of the Gulf of Aqaba have been identified through the analysis of multi-temporal satellite images with the aid of GIS analysis. The study area is subject to rapid and increasing changes in land-use/land-cover that resulting from natural and human activities such as flash flooding, seismic activity, landslides, and tourist and urban activities. This is in addition to the construction projects of roads, ports, PowerStation stations, mineral exploration, beaches, and tourist villages resulting from major environmental impacts. The current study aims to use Remote Sensing and GIS tools to investigate, monitor, and assess geo-hazards through the building of a geographical database. Several techniques have been developed over the last decade mostly to study the geological and geomorphologic characteristics of the terrain; land-use and land-cover changes. These are based on satellite imagery and Digital Elevation Models (DEM) to determine the topographic features, and geo-hazards maps. It is concluded that integrated approaches to monitoring can successfully be used to assess the environmental impacts along the Gulf of Aqaba coastal zone.

    ABSTRACT: The aim of the present study is to assess the present geo-environmental hazards, both flash flooding and seismic activity in the western part of Gulf of Suez. Assessment includes the analysis of satellite images, topographical, geological and other ancillary geological data using GIS technology. GIS data integration and analysis, including morphometric, local seismic activity and structural data analysis indicated that the area is under threat from two types of geo-hazards. Morphometric analysis strongly supported the high probability of flash flooding in different sites within the study area. The structural lineaments, extracted from an enhanced ETM+7 image, showed that the majority of seismic activity is related to segments of the fault system of the Gulf of Suez and the Gulf of Aqaba. The seismic activity hazard was taken into consideration through the identification of the sources of events. Seismic activity in the study area markedly increases from north to south. The distribution of the seismic activity pattern and data analysis for the study area clearly exhibits the urgent need for an assessment and rehabilitation program to mitigate geo-hazard along the existing structures.

    ABSTRACT: Desertification constitutes a major concern of countries in the Sahelian region of North Africa. This phenomenon is responsible for the degradation of the natural habitat and for the arable land disappearance. With the development of remote sensing techniques, it became possible to study this phenomenon at spatial and temporal scales and to analyze the interaction between the various elements of the environment in relation to soil dynamics and human activity. This study was an attempt to use high-resolution satellite data, specifically Quick Bird, to thematically map the geomorphology of the study area, particularly active dunes. Visual interpretation combined with supervised classification using training site tests allowed us to perform a precise identification and led us to an accurate mapping desertification sensibility. As a result, it appears that Oudia may be threatened by the encroachment of sand dunes and significant wind activity. In conclusion this study strongly recommends the use of these new techniques of remote sensing in assessment and mapping of desertification.

    ABSTRACT: Ecosystems in semi-arid regions appear to be undergoing degradation processes commonly described as desertification. Desertification has been widely recognized as one of the most serious environmental problems in world, although its concept and causes are still debated in scientific communities. The semi-arid region in North Africa is ideal for investigating the processes and mechanisms of desertification due to its very sensitive ecosystem. The desertification constitutes one of the major concerns of the countries of the Sahel and North Africa. This phenomenon is responsible for the degradation of natural habitat and for arable land disappearance. Using the Sandy land of Choott El-Garssa, a former dormant dunes and wetlands environment, we monitored the variation of the desertified land and the wetlands in order to assess the climatic and human impacts on the processes of desertification. The research methods included digital image processing of high resolution of satellite data and field verification. Remote sensing data shows that the wetlands were larger in Oudia area. The variation of the extension of mobile dunes is in inverse proportion to that of wetlands. The main process of desertification is the reactivation of dormant sand dunes. The changes of wetlands and desertified lands correlate considerably well with the variations of local precipitation and temperature, suggesting that climate might be the key factor triggering desertification in the Oudia area. In other sandy lands of Oudia area, however, human activities might be the key factor causing desertification and land degradation. With the development of remote sensing techniques, it became possible to study this phenomenon through several scales and to analyze the interaction between the various elements of the environment in relation with the dynamics of soil and the human activity. This study was an attempt to use high-resolution satellite data Quick Bird for mapping desertification in the zone of Tozeur. The example selected for this paper is the sector of Oudia located about 12 km North West of Tozeur. The methodology used is the simultaneous approach of geomorphological and digital analysis of high-resolution satellite data for defining and mapping the desertification landscape. Visual interpretation combined with supervised classification using training site tests allowed us to perform a precise identification and led us to an accurate mapping desertification sensibility. As a result, it appears that Oudia is threatened by the encroachment of sand dunes and a significant wind activity. In conclusion, the study strongly recommends the use of these new techniques of remote sensing in desertification assessment and mapping.

    ABSTRACT: Land assessment is of great importance in guiding decisions for planning land uses. The main objective of this study is to determine land resources, soil degradation and to evaluate land utilization types and their suitability in El-Maghara area. Field verification, digital soil data and land use related (satellite data, DEM and ancillary maps) data were used and analyzed with Remote Sensing (RS) and Geographic Information Systems (GIS) techniques and a new digital soil maps and database were generated for El-Maghara area. The soils of El-Maghara area were classified using last U.S.D.A. Soil Taxonomy. RS and GIS techniques were successfully applied in this land assessment study. GIS software was used to determine potential land use groups and suitability classes for agricultural uses of the study area. Five mapping units were identified using the most effective soil properties in the spatial distribution pattern. Each map unit is characterized by different soil properties and the mode of sedimentations. The resulted suitability factors maps for agricultural uses are soil classification units, fertility, capability, suitability of water and environmental conditions. The capability soil map is classified as class C2, C3, C4, C5 and C6 and the soil fertility was classified into five classes. The suitability results showed that 16.4% to 66.8% of the studied soils are found to be poorly to highly suitable for agricultural uses. These soils are classified as Typic Torrifluvents, Typic Quartzipsamments and Typic Torripsamments. The land suitability classifications of El-Maghara soils area are classified in good, fair, poor, very poor and non-agriculture soils grades. The current work discusses various approaches for soil erosion hazard assessment and deriving temporal ecosystem changes. Manifestation of soil degradation of El-Maghara area includes mining, quarrying, salinity of water irrigation, land deterioration by intensive grazing and infringement of mobile sand bodies or sand duns and water erosions.
