“… Various geological maps of Egypt (Conoco, 1987; EGSMA, 1994) are used to classify different rock units and characterize the training classes. The training classes are described for maximum likelihood classification and accuracy assessment (Abuzied et al., 2016a, 2020; Abuzied & Mansour, 2019). Operational Land Imager (OLI) Landsat‐8 satellite images, produced in June 2018, are selected to classify rock units, and delineate the structural features using a mixture of RS methods (Abuzied et al., 2020).…”

The appraisal of geothermal sites along Gulf of Suez, is important to develop the renewable energy resources in Egypt. An integrated approach based on remote sensing, Geographic Information System and geophysical methods were used to predict the ubication of promising geothermal sites. Multi‐source datasets were selected, analysed and integrated to develop a Geothermal Potential Model. Information‐Value and Weight‐of‐Evidence analyses were adopted to derive ranks and weights to spatial factors and their classes. The spatial factors were summarized in eight thematic maps indicating the possible sites of geothermal reservoirs. The developed geothermal potential model defines the promising sites, which are distributed in Ras‐Badran, Ras‐Matarma, Abu‐Durba, El‐Tur and some other locations in southwestern Gulf of Suez. Seismic interpretation is a fundamental tool for depicting subsurface major faults controlling the geothermal reservoir in the promising sites. The holistic integrated approach provides a powerful technique to design development plans in the study area.

“…The stability of a slope is influenced by several factors that are mostly constant, such as geometry, some soil properties and stratification [8]. Other authors prefer to use the term mass movement, which are caused by contributing and triggering factors [9]- [11]. In general, the degree of inclination, altitude, fault, lithology, drainage, soil use and type of soil are considered contributing factors, while precipitation, earthquakes and human interventions are triggering factors.…”

Introduction: The article presents research results on the analysis of slope instability processes, conducted at the Universidad Pedagógica y Tecnológica de Colombia in 2019. Problem: Slope instability processes are permanently present in the state of Boyacá – Colombia. The stability analysis through the application of conventional limit equilibrium methods does not reflect the real conditions of mechanical resistance of the materials found. Aim: Analyze slope instability processes utilizing the finite element method in two critical spots located on the road that connects the city of Tunja with the town of Miraflores. Methods: Start with the search and compilation of information from critical spots with relevant geotechnical characterization on roads in the state, thereby permitting the identification of two unstable critical spots. With the use of geological, geotechnical and hydrological information, the mechanical behavior of the materials is modelled through the software Slide and Midas GTS NX. Results: The estimation of material stability through the finite element method shows more reliable results compared to the actual behavior of the studied locations and compared to the methods based on limit equilibrium. Conclusion:The use of this numerical simulation technique is recommended to replace conventional methods, being an affordable and effective tool for the analysis of instability processes. Originality: Most analyses of instability processes conducted in the state of Boyacá – Colombiado not use the finite element method. Limitations: The estimation of material stability is based on a constitutive model for soil and another for rock.

“…Landslides are caused by rainfall, earthquakes, and other triggers (e.g., Abuzied and Alrefaee 2019;Abuzied et al 2016;Hong et al 2005). In particular, rainfall-induced landslides often cause significant damage (Saito et al 2010b).…”

Evaluating how the changes in rainfall caused landslides is important to prevent sediment disasters. Using the soil water index (SWI) and a three-layer tank model, this study examined the relationship between the occurrence of landslides and long-term changes in rainfall in Miyagawa Village, Mie Prefecture, Japan, where shallow and deep-seated landslides have occurred at different times. The three-layer tank model detected the effects of long-term changes in rainfall on landslides. We educated that the change in the first storage tank layer indicates the potential risk of shallow landslides, while that in the second and third storage tanks indicates the potential risk of deep-seated landslides. Our method could be used to examine the effects of long-term changes in rainfall on landslides in the same region at different times, or over a wider area. Besides, these results are valid because the three-layer tank model used to calculate the SWI is applied throughout Japan, and its effectiveness has been verified.
