This paper discusses the effect of various climatic conditions that pertain to passive design measurements and their relationships with building configurations to improve indoor thermal comfort based on the different climate zones in Egypt to support Egypt’s sustainability agenda 2030. We find the most appropriate design settings that can increase the indoor thermal comfort, such as building orientation and shape. These settings can be modeled using DesignBuilder software combined with Egyptian meteorological data. This software is used accompanied by computational fluid dynamics to numerically assess the outcomes of different changes, by simulating indoor climate condition factors such as wind speed and temperature. Natural ventilation simulations were performed for four different shapes to create comprehensive dataset scenarios covering a general range of shapes and orientations. Seven scenarios were optimized to put forward a series of building bioclimatic design approaches for the different characteristic regions. The results indicated that the temperature decreased by about 3.2%, and the air velocity increased within the study domain by 200% in the best and the worst cases, respectively, of the four different shapes. The results of the study gave evidence that the configuration of buildings, direction, and wind speed are very important factors for defining the natural ventilation within these domains to support the green building concept and the sustainable design for a better lifestyle.

The present situation in Egypt is framed by the scarcity of water that is under serious pressure. Water resources, on the one hand, are at the core of sustainable development and critical to socio-economic growth. On the other hand, water utilized from groundwater is considered an important source of water supply in Egypt after the River Nile. This chapter captures the groundwater in Egypt’s deserts (in terms of findings and suggestions) and provides ideas extracted from the volume cases. In addition, some (update) findings from a few recently published research work related to the groundwater covered themes. This chapter provides the present problems faced by the Groundwater in Egypt’s Deserts with a set of recommendations to safeguard the water to supply the populations and farmers with water. It covers topics that include groundwater occurrence, ecosystem services of groundwater, water logging, quantity and quality of groundwater in Egypt’s deserts and their Management and future use of groundwater in expanding areas.

In hydraulic structures design, using cutoff walls is essential to reduce and control the resultant uplift force (U), seepage discharge (Q), and exit hydraulic gradient (i). This research investigates the effectiveness of inclined double cutoff walls under hydraulic structures, considering the influence of depths, locations, and inclination angles of the upstream and downstream cutoff walls by using Finite Element Method (FEM). The results confirmed that installing a deeper cutoff wall on the downstream reduces the exit gradient even further. In the case of the cutoff walls located in the upstream and downstream ends, the exit gradient will be less than when the cutoff walls are installed at a closer distance. Increasing the inclination angle of downstream cutoff wall has a major impact on exit gradient reduction. Embedment of cutoff walls in the upstream and downstream ends with right angles and equal depths reduces the seepage discharge more than other cases.

Africa is the second populous continent, and its population has the fastest growing rate. Some African countries are still plagued by poverty, poor sanitary conditions and limited resources, such as clean drinking water, food supply, electricity, and effective waste management systems. Underfunded healthcare systems, poor training and lack of awareness of policies and legislations on handling medical waste have led to increased improper handling of waste within hospitals, healthcare facilities and transportation and storage of medical waste. Some countries, including Ethiopia, Botswana, Nigeria and Algeria, do not have national guidelines in place to adhere to the correct disposal of such wastage. Incineration is often the favoured disposal method due to the rapid diminishment of up to 90% of waste, as well as production of heat for boilers or for energy production. This type of method – if not applying the right technologies – potentially creates hazardous risks of its own, such as harmful emissions and residuals. In this study, the sustainability aspects of medical waste management in Africa were reviewed to present resilient solutions for health and environment protection for the next generation in Africa. The findings of this research introduce policies, possible advices and solutions associated with sustainability and medical waste management that can support decision-makers in developing strategies for the sustainability by using the eco-friendly technologies for efficient medical waste treatment and disposal methods and also can serve as a link between the healthcare system, decision-makers, and stakeholders in developing health policies and programmes.

Groundwater is the main source of drinking water in the Nile Delta. Unfortunately, it might be polluted by seepage from polluted streams. This study was carried out to investigate the possible measures to protect groundwater in the Nile delta aquifer using a numerical model (MT3DMS - Mass Transport 3-Dimension Multi-Species). The sources of groundwater contamination were identified and the total dissolved solids (TDS) was taken as an indicator for the contamination. Different strategies were investigated for mitigating the impact of polluted water: i) allocating polluted drains and canals in lower permeability layers; ii) installing cut-off walls in the polluted drains, and finally, iii) using lining materials in polluted drains and canals. Results indicated these measures effective to mitigate the groundwater pollution. In particular, the cut-off wall was effective for contamination reduction in shallow aquifers, whereas it had no effect in the deep aquifer, while lining materials in polluted drains and canals were able to prevent contamination and to protect the freshwater in the aquifers. It is worth mentioning that this study was partially supported by a bilateral project between ASRT (Egypt) and CNR (Italy).

This study deals with the quantitative estimation of the accumulated sediment capacity within the period from the initiation of the storage process of Lake Nubia in 1964 until 2012, by using field measurements and remote sensing data.. The bed levels of the study area related to year 1964 were extracted from a tri-dimensional model of the lake derived from a topographic map, based on observations anterior to lake filling. This map was compared with the bed levels estimated for the year 2012, which were extracted from remote sensing data, with the aim to estimate the sediment capacity. The utilized technique for estimating the bathymetric data (depths) from satellite images relies on establishing a Multiple Linear Regression (MLR) model between in situ measurements and reflectance data from multi-spectral optical satellite observations. The Multiple Linear Regression (MLR) model showed good results in the correlation between field measurements and remote sensing data. The current approach provides flexibility as well as effective time and cost management in calculating depths from remote sensing data when compared to the traditional method applied by Aswan High Dam Authority (AHDA). This study is in the framework of a bilateral project between ASRT of Egypt and CNR of Italy, which is still running.

ABSTRACT
With the fast and highly growing demand for all possible ways of remote work as a result of COVID19 pandemic, new technologies using Satellite data were highly encouraged for multidisciplinary applications in different fields such as; agriculture, climate change, environment, coastal management, maritime, security and Blue Economy.
This work supports applying Satellite Derived Bathymetry (SDB) with the available low-cost multispectral satellite imagery applications, instruments and readily accessible data for different areas with only their benthic parameters, water characteristics and atmospheric conditions. The main goal of this work is to derive bathymetric data needed for different hydrographic applications, such as: nautical charting, coastal engineering, water quality monitoring, sediment movement monitoring and supporting both green carbon and marine data science. Also, this work proposes and assesses a SDB procedure that makes use of publicly-available multispectral satellite images (Sentinel2 MSI) and applies algorithms available in the SNAP software package for extracting bathymetry and supporting bathymetric layers against highly expensive traditional in-situ hydrographic surveys. The procedure was applied at SAFAGA harbor area, located south of Hurghada at (26°44′N, 33°56′E), on the Egyptian Red Sea coast. SAFAGA controls important maritime traffic line in Red Sea such as (Safaga – Deba, Saudi Arabia) maritime cruises. SAFAGA depths change between 6 m to 22m surrounded by many shoal batches and confined waters that largely affect maritime safety of navigation. Therefore, there is always a high demand for updated nautical charts which this work supports. The outcome of this work provides and fulfils those demands with bathymetric layers data for the approach channel and harbour usage bands electronic nautical chart of SAFAGA with reasonable accuracies. The coefficient of determination (R2) differs between 0.42 to 0.71 after applying water column correction by Lyzenga algorithm and deriving bathymetric data depending on reflectance /radiance of optical imagery collected by sentinel2 missions with in-situ depth data values relationship by Stumpf equation. The adopted approach proved to give highly reasonable results that could be used in nautical charts compilation. Similar methodologies could be applied to inland water bodies. This study is part of the MSc Thesis of the first author and is in the framework of a bilateral project between ASRT of Egypt and CNR of Italy which is still running.

Water shortage, human population increase, and lack of food resources have directed societies towards sustainable energy and water resources, especially for agriculture. While open agriculture requires a massive amount of water and energy, the requirements of horticultural systems can be controlled to provide standard conditions for the plants to grow, with significant decrease in water consumption. A greenhouse is a transparent indoor environment used for horticulture, as it allows for reasonable control of the microclimate conditions (e.g., temperature, air velocity, rate of ventilation, and humidity). While such systems create a controlled environment for the plants, the greenhouses need ventilation to provide fresh air. In order to have a sustainable venting mechanism, a novel solution has been proposed in this study providing a naturally ventilating system required for the plants, while at the same time reducing the energy requirements for cooling or other forced ventilation techniques. Computational fluid dynamics (CFD) was used to analyse the ventilation requirements for different vent opening scenarios, showing the importance of inlet locations for the proposed sustainable greenhouse system.

Industrial activities produce millions of tons of hazardous waste annually, which are eventually disposed of in landfills. In this study, the effect of saline industrial hazardous landfill leachate (SIHLL) on the geotechnical properties of natural and contaminated silty clay soil was investigated via laboratory-based experiments in order to assess the potential application of this soil as a barrier lining in a saline hazardous industrial waste landfill. Contaminated soil specimens were prepared by mixing natural soil with SIHLL at different concentrations (0%, 25%, 50%, 75%, and 100%). The results revealed that the permeability coefficient (k) and the total pore volume (TPV) of the SIHLL-contaminated soil decreased from 8.6 × 10−8 to 5.91 × 10−8 cm/s and from 10.24 × 10−2 to 7.65 × 10−2 cm3/g, respectively, as the SIHLL concentration was increased from 0 to 50%. These effects were mainly due to the high concentration of salts in the SIHLL. The addition of SIHLL reduced the optimum moisture content (OMC) of the soil from 18% for natural soil to 14% for 100% SIHLL-contaminated soil, and the maximum dry density (MDD) recorded (for 100% SIHLL-contaminated soil) was 17.95 kN/m3. The angle of internal friction (φ) of the soil dropped from 27.8° for 0% SIHLL-contaminated soil to 23.7° for 100% SIHLL-contaminated soil. Also, the cohesion (c) decreased as the SIHLL concentration increased. In addition, considerable lowering of the consistency limits was observed for the SIHLL-contaminated soils. Based on these findings, the studied silty clay soil would be suitable for use in the construction of a new hazardous solid-waste landfill liner due to its low permeability and widespread availability in Egypt.

It is possible to take advantage of nanomaterials' properties to improve water-based drilling fluids' flux and physical properties. In this paper, glycine methyl ester hydrochloride was synthesized, and the chemical structure was verified to be used as a surface modifier of graphene oxide. At the same time, graphene oxide was prepared from graphite and chlorinated with thionyl chloride, and a nucleophilic substitution reaction was performed to increase the hydrophilicity of graphene oxide. FTIR, Raman, HRTEM, and XRD techniques have identified the prepared and obtained materials from chlorinated graphene oxide's reaction with glycine methyl ester hydrochloride. The glycine-modified graphene oxide (GO) was evaluated as drilling-fluid additives at different concentrations (2.66%, 5.32%, and 10.64%) to enhancement the thermal stability of water-based drilling fluid and reducing the filtration loss. The obtained results confirmed that the successful glycine-modified graphene oxide/bentonite to enhance both thermal stability (up to 350 °F) and filtration loss.

The capability of drilling fluid to endure high temperatures is an important characteristic of drilling fluids. Natural polymers are commonly used as additives for drilling fluids to improve their rheological properties. Starch is one of them, that is extensively used in the drilling due to economics. However, the thermal stability of water-based mud included starch is low. Herein, diethanolamine is used to enhance the rheological and filtration loss properties of the water-based fluids (WBF) through chemical modification of Lewis acid sites in bentonite framework and the formation of a cross-linked hydrogen bond with the starch compound. The effect of starch as an additive to WBF was studied at 0.56% and 0.94% in the bentonite-based fluid. The revealed data indicated an apparent improvement had been achieved after the addition of starch (0.94%). The effect of diethanolamine (DEA) on the rheological properties of starch-bentonite system, DEA was used as an additive at three ratios of 0.19%, 0.37%, and 0.75, at 300 °F, 325 °F, 350 °F, and 375 °F. The obtained data indicated that both rheological and filtration loss properties were enhanced, eventually at elevated temperature of 350 °F. The interaction in bentonite-starch, bentonite-DEA, and bentonite-starch-DEA WBF was studied using FTIR, XRD, and Raman spectroscopy. The results indicated the formation of hydrogen bonds between all components, which increases the basal displacing between bentonite layers. That interaction leads to the enhancement of the rheological and filtration loss properties of the drilling fluid. The response surface methodology (RSM) was used with the central composite design to evaluate and improve the drilling fluid compositions in terms of various rheological parameters.

This study detects the removal of Cu2+ and Pb2+ metal ions, from aqueous solution using modified graphene oxide-thiosemicarbazide (mGO-TSC) nanocomposite. The chemical structure and morphology of the synthesized nanocomposite adsorbent of graphene oxide-thiosemicrbazide (mGO-TSC) were characterized using different spectroscopic analyses including: FTIR, Raman, TGA, and TEM analysis. The influences of different parameters including: immersion time, pH of the medium, initial metal ion concentration, and the used adsorbent amount were studied. Results revealed that increasing the immersion time and the adsorbent amount were increased the adsorption efficiency. Also, the efficiency was reversed after increasing the initial metal ions concentration. It was observed that the pH of the medium played a critical role on the efficiency metal ions adsorption. The adsorption study showed that the adsorption proceeds according to Freundlich adsorption isotherms. Also, the kinetic studies indicated that the adsorption process follow the pseudo-second-order kinetic model through the inter-particle diffusion mechanism. The modified adsorbent (mGO-TSC) showed effective reusability for four rounds with adsorption efficiency reached to 85% and 81.7% for Cu2+ and Pb2+, respectively. The mechanism of metal ions adsorption using GO and mGO-TSC was suggested based on the molecular energies optimization, which showed the effectiveness of sulfur and oxygen during the adsorption process.
