This paper presents a procedure for risk assessment for hydrological disasters considering the threshold rainfall and environmental and social criteria. A case study was carried out to test its feasibility in the northern region of the State of São Paulo, Brazil. The advantage of this procedure is that it only uses data available on government institutions and websites. For this reason, other regions and countries can easily adapt the procedure to their reality. Initially, the hydrological disasters were obtained i [...]

This paper presents a model for the similarity structure of the velocity profiles in air and water in the wave boundary layer, which provides predictions in terms of two parameters, F and R, of all its important properties, including the Charnock parameter, the surface drift velocity and the condition for the cancellation of the surface Stokes velocity by the surface current. The parameter, F, arises from the fetch variability of the wave field, and the parameter, R, arises from the duration variability of the wave [...]

The diffusion of distributed energy resources can overcome some challenges associated with the historical centralized model of electric power distribution. Decentralized generation by residential solar photovoltaic cells creates the potential for peer-to-peer (P2P) electricity trading, where households can act as consumers and prosumers to buy and sell renewable electricity. P2P energy markets are emerging at locations across the globe, and market performance is affected by various social, economic, and environment [...]

Oil-contaminated or oily wastewater (OW) is generated from various industrial and domestic premises. It consists of fats, oils, and greases and may contain petroleum fractions such as diesel oil, gasoline, and kerosene. It is regarded as one of the most hazardous wastewaters, causing serious environmental and health threats to ecosystems and human beings. The global increase in the discharge of OW coupled with stringent regulations for effluent discharge and incessant drive for the reuse of treated wastewater neces [...]

The amount of greenhouse gases has been growing dramatically in recent decades, producing global warming and causing climate change that affects the entire planet. To mitigate these emissions, several nations have committed to implementing measures to reduce emissions of these gases, with carbon dioxide being the main one. The transport sector is one of the leading carbon emitters. It needs to be the object of attention from government authorities and private companies so that sustainable solutions are planned and [...]

Tectonic geomorphology has been evidenced as an essential tool to define and measure recent tectonic deformation. The Nandakini River originates from Nanda Ghunti glacier at 6886 m in Lesser Himalaya. It covers about ~551 km2 basin area, with a fourth-order stream. It confluences with the Alaknanda River near Nand Prayag (at elevation 852 m), Chamoli district of Uttarakhand. The drainage pattern is predominantly dendritic in the study area. The morphotectonic indices are measured to know the tectonic activity of th [...]

Value co-creation in the digital innovation ecosystem is of great practical significance for promoting enterprise advantages and high-quality economic development. Digitalization reshapes the logic of value co-creation. Innovation activities are no longer focused only on the internal enterprise but also occur in the ecosystem of interaction and sharing with other heterogeneous and diverse subjects. How can value co-creation be achieved between the digital innovation ecosystems and how can they be coupled between th [...]

The review article discusses the application of biogeochemical technologies aimed at restoring biogeochemical cycles in agroecosystems, primarily in the microbial link regulating CO2 flows. The factors of management this microbial link when applying mineral and organic fertilizers are shown. The processes of mineralization of soil organic matter and methods of controlling soil's conjugate carbon- and nitrogen-mineralizing ability are considered. The changes in the productivity of agricultural ecosystems under condi [...]

Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also alter, impacting aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies wer [...]

Following the establishment of the United Nations’ Sustainable Development Goals, sustainability has been given increasing attention in the agenda of the built environment. Sustainability embraces three key elements, i.e., environment, economy and society. However, the social dimension receives the least attention and is largely overlooked compared to the environmental and economic sustainability. To bridge the gap, this paper will examine the various dimensions of social sustainability involved in the built enviro [...]
