Abstract In the world of advancement, the development of the urban environment by providing favorable and secure conditions to the population are always directed to environmental factors of various levels. The role in urban development and growth remains an integral part of their management. It should focus on improving the effectiveness of territorial utilization and enhancing environmental resources.The planning will be based on the information regarding the past and present events of the recognized ecological processes in cities. Currently, there are several issues in towns that need to be addressed effectively and efficiently. The poor urban environment is a significant issue which leads to ecological issues. The environmental factors are one of the most important aspects that people should consider when implementing growth plans in the urban areas. This paper explores environmental factors such as Density, Compactness, Fragment, Variation, Cohesion in urban territory design and management.

The Impact

This study deals with the use of remote sensing (RS), geographic information systems (GISs), hydrologic modeling (water modeling system, WMS), and hydraulic modeling (Hydrologic Engineering Center River Analysis System, HEC-RAS) to evaluate the impact of flash flood hazards on the sustainable urban development of Tabuk City, Kingdom of Saudi Arabia (KSA). Determining the impact of flood hazards on the urban area and developing alternatives for protection and prevention measures were the main aims of this work. Tabuk City is exposed to frequent flash flooding due to its location along the outlets of five major wadis. These wadis frequently carry flash floods, seriously impacting the urban areas of the city. WMS and HEC-HMS models and RS data were used to determine the paths and morphological characteristics of the wadis, the hydrographic flow of different drainage basins, flow rates and volumes, and the expansion of agricultural and urban areas from 1998 to 2018. Finally, hydraulic modeling of the HEC-RAS program was applied to delineate the urban areas that could be inundated with floodwater. Ultimately, the most suitable remedial measures are proposed to protect the future sustainable urban development of Tabuk City from flood hazards. This approach is rarely used in the KSA. We propose a novel method that could help decision-makers and planners in determining inundated flood zones before planning future urban and agricultural development in the KSA.

Recently, more and more often urban abandoned and depressed spaces that were previously used as industrial facilities or temporarily used are becoming the sphere of architectural and landscape transformations. These territories can occupy a significant part of the city. This paper examines the features of the formation of urban planning systems, as well as the impact of depressed spaces on the quality of the urban environment. This paper studies such depressed spaces as abandoned industrial areas and objects of unfinished construction. The paper assesses the impact of depressed spaces, identifies criteria that reflect the nature, scale and features of their impact on the environment, on the safety and quality of the urban environment, as well as their role in the structure of the city as a whole. The principles and features of the formation of such urban depressed spaces, as well as the patterns of their development are revealed. The features of the formation of open public space of urban systems, as well as ways of transforming depressed spaces, aimed at increasing their social significance, integrating them into the general urban development, and improving the ecological and social situation are considered. The paper concludes that the problem of restoration of depressed spaces is very important and urgent today. The creation of a continuous urban tissue is impossible without the reorganization of such spaces, as well as the creation of an integral compositional, functional and communication urban planning system.

Modern research on the sustainability of the urban environment mainly focuses on environmental factors like water, air, energy and transport, while urban identity rarely attracts attention. The concept of sustainability, which includes the identity of the urban environment, combines a wide range of factors, including urban planning and architectural objects, natural, geographical, cultural products and social norms. With modern architectural and urban development and globalization, cities are increasingly facing the problem of losing their original identity. In the context of the concept of the identity of the urban environment considered in this study, the role of urban planning objects, architecture and culture in the formation and maintenance of the unique identity of the city of Astrakhan and the need for considerable attention to the resource of identity for the development of the city and the region is stressed.

The Impact

In Europe, 70% of citizens live in urban areas and consume around 75% of the primary energy supply. In order to reduce the impact of energy consumption and improve the competitiveness of local energy systems, Energy Communities may help to address the challenges of urban sustainability and energy security through local energy production and self-consumption. Solar, biomass and wind are the main sources of renewable energy that are generally used in cities. However, not all the sources available in urban environment are usable, due to the limited availability, or other technical or non-technical limits and constraints. In order to promote renewable energy technologies in buildings it is necessary to consider architectural, cultural, energy, technical and economic feasibility. This work defines a methodology for the optimal design of grid connected PV-battery systems in urban environments. The model was applied to two districts located in the city of Turin with the aim of evaluating the technical feasibility of combining multiple residential users at city level. The purpose of this work is to promote self-consumption and self-sufficiency from the network, using the integration of solar energy with PV-battery systems, and to reduce electrical losses in favor of both the single user and the distribution system. Results show that different values of self-sufficiency and self-consumption can be reached depending on the shape and dimension of each building. It was shown that it is possible to satisfy the current requirements to become an Energy Community in an urban environment with good levels of self-sufficiency.

The Impact

Cities are an important resource for the socio-economic and regional development of the state. Urban development depends on resources, capital, labour force, which mobility from the impact of scientific and technological progress increases all the time. Resources don't belong largely to the concrete place anymore as it was before. That is why cities could think about the possibilities of increase of their attraction and competitiveness at the context of sustainable development. It means that one of the most important goals of the urban development and management is to create such kind of the urban environment which will be in line with the needs and requirements of the city inhabitants, which will be attractive for the foreign investors and tourists, which could compete with other cities. But the most important is that urban environment could give us all an opportunity to be active, participate and enjoy. The world practice shows that the use of the principles and instruments of the marketing for provision of sustainable urban development has positive impact on the socioeconomic and regional development of the state – it improves the investment environment, increases the rate of the economic investments, promotes business and tourism, improves the quality of education, increases welfare and mental development. The necessity of more detailed analysis of the importance of place marketing for sustainable urban development determines actuality of this research.

The Impact

With urban areas facing future longer duration heat-waves and temperature extremes from climate change and growing urban development, adaptation strategies are needed. Examining the role that increased tree cover and water availability can have on human thermal comfort (HTC) in urban areas as part of these strategies has been done using observations, but further work requires a modelling tool suited for this task. Sufficient model resolution is needed to resolve variables used to calculate HTC, as well as the ability to model the physiological processes of vegetation and their interaction with water and with the rest of the urban environment. The lack of such a model has been identified as a research gap in the urban climate area and has impaired the ability to fully examine the use of urban greenery and water for improved human thermal comfort. A new model, VTUF-3D (Vegetated Temperatures Of Urban Facets), addresses this gap by embedding the functionality of the MAESPA tree process model (Duursma & Medlyn 2012), that can model individual trees, vegetation, and soil components, within the TUF-3D (Krayenhoff & Voogt 2007) urban micro-climate model. An innovative tiling approach, allows the new model to account for important vegetative physiological processes and shading effects using configurable templates to allow representation of any type of vegetation or water sensitive design feature. The high resolution of VTUF-3D is sufficient to examine the processes that drive human thermal comfort (HTC). This allows detailed calculations of surface temperatures, mean radiant temperature (Tmrt), and a HTC index, the universal thermal climate index (UTCI), across an urban canyon. An extensive validation process, using three different observation data sets to validate a number of different and key aspects of the VTUF-3D model, has shown it performs well and is suitable for use to examine critical questions relating to the role of vegetation and water in the urban environment. A demonstration of the model using modelling scenarios of varying canopy cover shows that average peak daytime HTC improvements of 1◦C UTCI (and 2.3◦C UTCI) are possible in doubling (and quadrupling) existing street cover canopies, with localised effects under canopy cover approaching 5◦C UTCI. These scenarios also show the value of the existing canopy cover, as reductions and elimination of existing cover can create reductions in HTC of 2◦C UTCI. In addition, reductions in average air temperature (Ta) across urban canyons can differ by 1◦C between streets with differing canopy cover. After the development, validation, and demonstration of this new model, it is now possible to conduct further analysis to quantify the impact each individual tree can have on temperatures in urban canyons. Further, the model can help inform the optimal arrangement and quantity of trees to maximise temperature moderation effects and be used to generate best practices guidelines for urban greening.

Abstract Previous studies have shown that physicochemical properties of hair can be impacted by internal and environmental exposures ranging from chemical stressors to weather. Besides the effects on hair, these exposures, termed “exposome”, can act on specific organs including skin, as a synergistic damaging effect of UV exposure and pollution on human surfaces. The combination of several environmental factors such as sun exposure, temperature, relative humidity, air pollution and photo-oxidation caused by ground level ozone impacts hair properties such as melanin oxidation, protein content, surface quality and structural components. Therefore, exposome studies can reveal new hypotheses on how epithelia and hair could be affected by daily life environment and routine. The aim of this study was to evaluate the impact of several environmental aggressors on human surfaces, using portable and wearable devices for monitoring exposome. To better understand the underlying mechanisms associated with environmental factors, two subjects wore multiple sensors to capture the meteorological conditions biking through urban areas in summer and winter. Temperature, humidity, UV radiation and ozone concentration were recorded and hair swatches of different types, including natural, bleached/colored, colored and gray, were exposed on the helmets. Silicon wristbands were used on skin to identify main chemical aggressors. After exposure, hair swatches were analyzed by surface microscopy analysis, oxidation markers and more than 1,500 chemicals were evaluated on the bracelets. Correlated with GPS and monitoring data, all these results provide insights on how environmental stressors affect the quality of different hair types and body surface according to exposure routine. Our results suggest extreme climate conditions associated with hair damage and photo-oxidative marker linked to the environmental aggressors. Polycyclic aromatic hydrocarbons (PAH) indicate possible causes of hair damages. This is the first meteorotropic study of its kind, combining environmental aggressors related to hair damage, opening new research hypothesis further studies on exposome.

The Impact

Linking urban development and urban drainage models is a more and more popular approach when impacts of pavement of urban areas on sewer system performance are evaluated. As such an approach is a difficult task, this is not a feasible procedure for everyday engineering practice. We propose an alternative method, based on a developed simple near-quadratic relationship, which directly translates change (increase or decrease) of paved area into a change in the return period (RP) of the design rainfall event or design rainfall intensity. This formula is simple to use and compatible with existing design guidelines. A further advantage is that the calculated design RP can also be used to communicate the impact of a change in impervious areas to stakeholders or the public community. The method is developed using a set of 250 virtual and two real-world case studies and hydrodynamic simulations. It is validated on a small catchment for which we compare system performance and redesigned pipe diameters. Of course such a simplification contains different uncertainties. But these uncertainties have to be seen in the context of overall uncertainties when trying to predict city development into the future. Hence it still is a significant advantage compared to today's engineering practice.
