Summary: Informal settlement growth presents a significant challenge for developing countries as rural migration to urban areas leads to unplanned expansion beyond official city boundaries. Despite the rapid growth of informal housing, there is little focus on exploring tools and procedures for predicting its future expansion. Many studies have shown informal housing to be a widespread and dominant feature of urbanization in Egypt.

Summary: El-Tamad Field is a promising area for oil and gas in the onshore Nile Delta, and its reservoir was characterized and modeled through the analysis of seismic lines, core data, and real-time flowline resistivity measurements. The study revealed three main faults, with one major growth fault causing the formation of a rollover anticline fold. The variation in reservoir quality was attributed to the depositional setting of sand facies and shale facies.

Summary: This study utilized magnetic susceptibility as an indicator of soil contamination and assessed different land-use types in Greater Cairo, Egypt, using potentially toxic elements content and statistical and spatial analysis. The results showed that PTE concentrations varied with land-use types and were influenced by anthropogenic sources such as traffic emission, industrial activity, and agricultural practices.

Summary: There have been extensive studies on informal settlements across various disciplines, but there is limited knowledge about their complexity and dynamism. This study aims to develop a framework for understanding the multiple factors influencing the formation and transformation of informal settlements. Through an exploration of their characteristics and relationships, examination of growth and transformation variables, and a comparison of informal urban form and sustainability qualities, the study validates the intricacies of informal settlements. By conducting case studies in Greater Cairo, the study identifies critical characteristics and establishes correlations between them for developing intervention strategies.

Summary: Oil pollution is a global concern due to the rise in offshore oil production and transport. A study was conducted to map oceanographic parameters affecting oil pollution dispersion in the offshore zone of the Nile Delta, showing that sea surface temperature and coastal zone depth primarily influence the distribution of other parameters.

Summary: Depositional architecture and hydrocarbon-bearing reservoir detection in the Nile Delta Basin present challenges. Channel fill deposits are complex due to vertical stacking and different depositional stages. A study used an artificial neural network to detect gas and water-bearing reservoirs within complex depositional patterns. The ANN algorithm proved effective in discriminating gas-bearing intervals from water-bearing intervals, aiding in field development plans and volume tracking of water and gas.

Summary: Nowadays, development projects are happening rapidly in many developing countries. This study focuses on the Cairo-Suez District in Egypt, which is an important area for infrastructure projects and urbanization. It is crucial to reduce the risks of natural disasters in this area, so information supporting geo-environmental hazards assessment is needed. The Gabal Ataqa area is significant for its socioeconomic importance as an industrial zone in a national project. The study utilizes seismic reflection to detect faults and subsurface features in this area. Based on the results, it is recommended to relocate the industrial zone away from the identified faults.

Summary: This research focuses on determining local site characteristics and seismic ground motions in a specific area around the Nile River, south of Cairo City, Egypt. The study includes a microtremor survey to infer shear wave velocity and analysis of dispersion curves to obtain Vs profiles. Inversion processes and spectral ratio methods were used to estimate soil class, seismic amplification, and predominant frequency. The calculated parameters contribute to earthquake risk reduction in the study area.

Summary: This study investigates the sedimentological analysis and petrophysical properties of the Messinian Abu Madi reservoir in the offshore Nile Delta Basin, aiming to determine how facies heterogeneities control reservoir quality. The study combines core data and wireline logs to identify different clastic facies and their petrophysical characteristics. The results show that the reservoir quality is strongly influenced by the original composition and primary depositional facies, with the best reservoir quality occurring in massive sandstones. The study also reveals the high potential of Abu Madi sandstones as gas-bearing reservoirs in the offshore Nile Delta Basin.

Summary: Climate change has a direct impact on crop evapotranspiration, which in turn affects groundwater levels and aquifer storage. This study used numerical modeling to assess the long-term effects of climate change on groundwater flow in the Nile Delta aquifer in Egypt, showing that solar radiation, vapor pressure deficit, and humidity are key variables in predicting crop evapotranspiration. The results indicate an increase in crop evapotranspiration and a decrease in aquifer recharge, leading to a slight decline in groundwater storage.

Summary: This study conducted a comprehensive geochemical assessment of Oligocene-Pliocene source rocks in the onshore part of the Nile Delta Basin. The results showed fair to good organic richness with gas-prone kerogen types. The organic matter was deposited under suboxic to anoxic nearshore marine or lacustrine settings with contributions from various sources. The pre-Miocene source rocks were suggested as the most probable candidates for hydrocarbons in the area.

Summary: Greater Cairo's PM2.5 concentrations and their chemical composition are mainly influenced by land-use and local activities rather than meteorological conditions. The levels of PM2.5 exceed the WHO air quality guidelines both annually and daily, posing significant short- and long-term health risks to the population. Lead is the highest risk factor, primarily through ingestion rather than inhalation.

Summary: Bayhead sandstone reservoirs are complex and challenging due to their limited examples. This study focused on the characteristics and heterogeneities of these reservoirs using sedimentological, petrographical, and petrophysical aspects, with an example from the Manzala Gas Field. The study identified different sedimentary sub-environments within the bayhead delta reservoir and their impact on reservoir quality, highlighting the importance of depositional setting and diagenetic processes.

Summary: This study utilizes oxygen and hydrogen stable isotopes as tracers to determine the sources of groundwater recharge in the central Nile delta. The isotopic data indicate that surface water is heavily influenced by evaporation, while soil water and groundwater have lower isotopic contents. The studied groundwater is found to have mixed sources, with a combination of pre- and post- High Dam construction recharge. The influence of both freshwater and seawater mixing is observed in the deep groundwater, while the shallow groundwater shows signs of evaporation.
