industry is not sufficient as the priority goes for domestic use. To meet the increasing population growth and development, the authorities have considered building a new water retaining structure on some major temporary water streams. For this purpose, Chebabta Site on Meskiana Wadi was chosen as the future dam site. It is large enough to store the desired volume of water. This study investigates the conditions of the site and the adequacy of the ground as a foundation for the projected dam. The conditions of the site include the geological structure and mainly the presence of discontinuities in the formation on which the dam will be built, the nature of the lithologies under the foundation and the future lake, and the presence of any hazard. This site characterization is usually carried out using different methods in order to highlight any underground buried problematic structure. In this context, the different geophysical techniques remain the most used ones. Four geophysical methods were used in the case of Chebabta dam site, namely seismic refraction, constant separation traversing (CST), vertical electric sounding (VES) and electric resistivity tomography (ERT). The choice of the techniques and the location of the survey lines was made on the basis of the available geological data. In this sense, profiles were established on both banks of Meskiana Wadi. The obtained results allowed a better characterization of the geological structure, defining the limit between the surface cover and the bedrock, which is, in other words, the limit between the weathered zone and the bedrock. Their respective thicknesses were also determined by seismic refraction and VES. However, ERT succeeded in estimating the thickness of alluvial deposits in the left bank of the Wadi and positioning a fault structure passing at the east of the study area.

Floods are one of the causes of ground movement and displacement, and due to rapid urbanization and urban growth may occur more frequently than before. The characteristics of an urban drainage system can define the occurrence and extent of flooding, where catchment elements have a determining role. This document presents the numerical investigation of the hydraulic inlet efficiency and the discharge coefficient of seven types of grate inlets. The FLOW-3D® simulator is used to test the gratings at a full scale, under flow rates of Q = 24, 34.1, 44, 100, 200 and 300 L/s, preserving the configuration of the experimental prototype with longitudinal slopes of 1.0%, 1.5% and 2.0% and a fixed cross slope, for a total of 126 models. Based on the results, hydraulic inlet efficiency curves and discharge coefficients are constructed for each type and a longitudinal slope condition. The results are adjusted with empirical formulations proposed in other investigations, serving to verify the results of physical testing of prototypes.

Ensuring the proper quality of the environment is a foreground and important task for achieving sustainable development goals in contemporary urban societies. Therefore, the aim of the research is to study the air pollution on the territories neighboring multi-level interchanges and assess the additional load on the lower levels based on the analysis of physico-chemical properties of harmful substances, which are exhausts components. The scientific novelty of the paper and the authors’ contribution is in determining the level of ecological danger of territories neighboring multi-level interchanges as a result of the summation effect from emissions of vehicle flows, physical and chemical properties of pollutants, and processes of their sedimentation. To predict the pollution level of the roadside air, the model of torch approximation based on the K-theory and the equations of turbulent diffusion was used. Both mathematical modeling and visualization were performed by the Mathcad software package. Particular attention was paid to the analysis of the environmental situation neighboring multi-level interchanges and urban objects in terms of their pollution with nitrogen oxides and particulate matter PM10. Research has shown that due to the sedimentation processes a significant increase of the technogenic load on the interchange first level road will be observed. It was found that, compared to the upper road, the technogenic load in the center of the lower road increases on average by 1.4–1.6 times in terms of nitrogen oxides and by 1.5–1.6 times in terms of PM10. The territory with the harmful substances maximum permissible concentration excess is significantly increased. So, taking into account that multi-level interchanges are much more environmentally acceptable than surface sections of roads with traffic lights and pedestrian crossings, they still pose danger to the health of people who stay for a long time at the transport stops, move on the sidewalks and underground crossings, as well as for vehicle drivers and passengers. Thus, it is recommended not to place on the territories neighboring multi-level interchanges public transport stops, cafes, shops, and other city infrastructure objects, as well as to remove the existing ones.

Batu East Java, Indonesia, as a tourist city, is categorized as a disaster-prone area; hence city resilience should be improved. Increasing resilience has a function in protecting the city from the rising number of disaster risks. This study aims to analyze the regional capacity based on the Regional Disaster Management Agency (Badan Penanggulangan Bencana Daerah – BPBD) capacity assessment criteria using the resilient stage based on Making Cities Resilient 2030 (MCR2030) and to determine the relationship between the BPBD capacity assessment criteria and the MCR2030 assessment. This study used a mixed methodology with a sequential explanatory design. The data collection technique involved 55 respondents using a purposive technique. The data analysis is based on the capacity assessment results in Batu City, which reached “moderate” criteria since the disaster risk index tends to decrease while the threat level rises. According to MCR2030, Batu City achieved 79.04% and was classified in stage C (progression implementation) because BPBD well defined the knowledge and planning stages for Batu City. This research indicated a significant gap between BPBD and other organizations, indicating that the “moderate” capacity and stage C categories only apply to BPBD. Other organizations, particularly in the economic and tourism sectors, are aware of the risks at stage B (planning) but have not yet developed a comprehensive plan or strategy to manage them. In contrast to the MCR2030 assessment, practically all respondents outside the BPBD stated that they had not participated in any regulations or public consultations in the past year and were unaware of such activities. The critical success of MCR2030 is the creation of resilience between stakeholders and local organizations; therefore, the suitability between the MCR2030 assessment and the capacity of BPBD can be used as a reference and adapted by other organizations, particularly the tourism industry in Batu City.
印尼东爪哇岛的峇都作为旅游城市,被划分为灾害易发区;因此,应该提高城市的韧性。增强韧性可以保护城市免受越来越多的灾害风险的影响。本研究旨在利用基于《城市韧性2030》(Making Cities resilient 2030, MCR2030)的弹性阶段,基于区域灾害管理局(Badan Penanggulangan Bencana Daerah - BPBD)的能力评估标准分析区域能力,并确定BPBD能力评估标准与MCR2030评估之间的关系。本研究采用顺序解释设计的混合方法。数据收集技术涉及55名受访者,使用有目的的技术。数据分析基于巴图市的能力评估结果,该城市达到了“中等”标准,因为灾害风险指数趋于下降,而威胁级别上升。根据MCR2030,由于BPBD很好地定义了拔都市的知识和规划阶段,拔都市实现了79.04%,并被归类为C阶段(逐步实施)。该研究表明,BPBD与其他组织之间存在显著差距,表明“中等”能力和C阶段类别仅适用于BPBD。其他组织,特别是经济和旅游部门的组织,已意识到B阶段(规划)的风险,但尚未制定管理这些风险的全面计划或战略。与MCR2030评估相反,几乎所有BPBD以外的受访者都表示,他们在过去一年中没有参与任何法规或公众咨询,也不知道此类活动。《2030年可持续发展战略》的关键成功在于在利益攸关方和地方组织之间建立复原力;因此,MCR2030评估与BPBD能力之间的适用性可以作为其他组织,特别是Batu市旅游业的参考和调整。

Industrial zones are considered one of the most important sectors of economic development in any country. All countries seek to develop these zones and transform them into the fourth and fifth industrial revolution zones. This paper relies on an extrapolation approach and comparative analysis of the industrial and economic zones that include the currently enforced policies dealing with these zones all over the world. Accordingly, this study consists of three main stages. The first stage concerns reviewing the concepts and definitions of industrial and economic zones, defining policies for dealing with them, and then concluding the bases and criteria of those policies. The second stage focuses on defining the criteria of the fourth industrial revolution industrial zones, then determining the criteria for differentiating between the current economic zones according to their suitability to absorb the fourth-generation industries, and finally determining the criteria for the localization of these industries spatially, relying on Fuzzy GIS methods to identify the best sites for localizing high-quality industries. The third stage is about conducting a field application to the Suez Canal area in Egypt to determine the best high-tech industrial site within the selected area in Egypt. The site identified as the most suitable for the settlement of high-tech industries is the area located in the northwest and southeast of the special economic zone (SEZ), northwest of the Suez Canal, with an area of 22 km², a weight of 0.357724, and a score of 20.

This study aims initially to evaluate the quality of different soundscapes in the public space of the city of Biskra, in Algeria. A total of 35 participants took part in a laboratory experiment, where 28 sound clips of one-minute duration taken from public spaces in the city were used as stimuli. The A-weighted equivalent continuous sound pressure level (LAeq,1min) was calculated. The participants rated the quality of the soundscape using attribute scales provided in their own native language. The results of the questionnaire on the recorded soundtracks confirm that the immediate environment affects the ambient sound level and the quality of the sound environment, where the sound environments of the areas located near the roads, with a high mechanical flow, are considered the most unpleasant and noisy, with a high A-weighted equivalent continuous sound pressure level (LAeq,1min). The findings of this study indicate that there are statistically significant correlations between pleasantness and loudness, presence of mechanical sounds, presence of non-mechanical sounds, and a sound exposure level. In addition, this study shows that there is a significant positive correlation between pleasantness and the presence of non-mechanical sounds. The results also showed an inverse relationship between the presence of mechanical and non-mechanical sounds, and that the absence of mechanical sounds allows natural and human sounds to be more audible, making the soundscape more pleasant and calm according to the results of the questionnaire. From this study, the duality LAeq,1min and the components of the soundscape are very representative indicators of the quality of the soundscape.

The rapid growth of urbanization exposes the environment to severe issues that threaten the quality of life. High land surface temperature (LST) is one of the most prominent issues in large cities where anthropogenic activities are accumulated, energy consumption and gas emissions increase, forming urban heat islands (UHI). In this research, the LST and the UHI formations were used as indicators to inspect and evaluate the environmental status of Kuwait’s urban area, which recently recorded a notable rise in air temperature. The LST spatial and temporal changes were examined and analyzed by utilizing satellite images of Landsat-8 for the period 2013–2020. The relationship between LST and air temperature was determined using the linear regression method. UHIs formation sites were investigated on different surfaces using the land use map. Results revealed that the LST average increased by 3°C in 2020 within seven years, and a strong positive relationship was observed between the LST and the air temperature. The UHI was mainly concentrated in industrial areas, oil fields, and airports. Moreover, the LST in the rural area reached 41.47°C, which is 4°C higher than it was in 2013. UHI intensity was calculated to assess the extent of variability in the LST between urban and rural areas; this intensity was lower in 2020 than in 2013 due to vegetation reduction in 2020. The continuous rise of the LST in Kuwait could lead to an inevitable environmental issue. Vegetation and water bodies play a significant role in moderating the LST, and these types of land coverage are rare in Kuwait. This research may contribute to controlling the temperature rise in UHI accumulation areas by following appropriate environmental solutions, sustainable urban planning, and encouraging the greening process.

Biochar is a carbonized material obtained from the pyrolysis of biomass produced in a limiting environment of zero or very low oxygen. Its interest lies in its versatility for different applications in the water treatment, soil pollution, mitigation of greenhouse gases, etc. The synergy of this product with other amendments such as compost has been studied for different applications in the soil, including environmental remediation, crop yield, etc. The aim of the research is to identify the relevant aspects in the scientific literature of biochar, compost and soil through a bibliometric analysis for which 753 articles were selected from the Scopus database, having as keywords “biochar”, “compost” and “soil”. This research used R software, specifically the package Bibliometrix, to analyze descriptive analysis, author sources, document metrics, citation, co-citation analysis, co-occurrence network, co-word analysis, and collaboration analysis. Results showed that Zhang Z is the author with the greatest number of documents, and with a higher H index. Science of The Total Environment, Bioresource Technology, and Agronomy are the 3 topmost relevant sources.

Eggshell waste and husk ash are abundant in Indonesia, with a population of 263 million, which is estimated to reach 483,920 tons and 10 million tons, respectively. However, this waste has not been utilized optimally, so it has a negative impact on the environment. This study aims to analyze the quality (compressive strength and water absorption) of a mixture of eggshells and husk ash as paving blocks for buildings to reduce the environmental burden. The experiment was carried out using a 2 factor factorial design: eggshells (4 levels: 0%, 5%, 7% and 15%); and husk ash (4 levels: 0%, 5%, 8% and 10%). The data were analyzed using analysis of variance, followed by analysis of mean using the least significant difference (LSD). The results showed that the mixture of eggs and husk ash had good quality, so it could reduce the need for Portland cement, which has a negative impact on the environment during production process. The best quality of a paving block was a mixture of 10% of husk ash and 15% of eggshells (A4B4 treatment) with the compressive strength value of 39 Mpa and water absorption of 5.8% (good).

Background. Renovation of existing buildings has become a crucial tool to keep the built environment functional, by which unnecessary waste of resources can be reduced. Although many assessment methods and indicators are set, with the booming “renovation wave”, a question that counters us is how influential and intact these are as a measuring tool. Several debates have emerged in the literature on the integration of different indicators and approaches to have a better way of accessing the buildings. Purpose. The aim of the study was, first, to have a set of integrated indicators for the renovation of residential buildings and, second, to develop an assessment methodology aimed at a comprehensive evaluation of the renovation process throughout its lifecycle stages. A requirement specification and an outline of the tool were developed based on the literature review and the survey. Design. The study has applied a qualitative multi-method research approach, including an online survey with experts, and case studies. The survey was part of renovation needs, barriers and evaluation methods and indicators comprising four sections addressed to experts about building renovation. The aim was, besides collecting general knowledge about the renovation in practice, to identify key indicators and areas where development or modification could have effect during the renovation. The developed methodology was applied in a case scenario of a multi-apartment building in Lithuania. Conclusions. This paper included the development of a combined methodology which applies to the renovation of the existing multi-apartment buildings with a checklist of indicators corresponding to environment, economic, and social aspects.
