Abstract:
AbstractLong-distance tunnels are essential hydraulic structures that guarantee the safe operation and optimal performance of engineering projects. Monitoring the operational status of tunnels through regular inspections is crucial to promptly detect defects such as seepage, collapses, and damages. This proactive approach prevents structural instability, damages, and blockages, ensuring the safe and stable operation of engineering projects. Water conveyance tunnels are typically long-distance, enclosed spaces with no illumination and no satellite navigation signals. Traditional manual inspection methods suffer from low efficiency, poor accuracy, and high safety risks. The tunnel defect detection method based on image automatic collection and 3D reconstruction addresses these challenges. It enables rapid inspections during flood periods and comprehensive examinations during dry seasons, adapting to the tunnel's water conditions. This method facilitates unmanned intelligent inspections of long-distance tunnels, three-dimensional visualization, and multi-period comparative analysis of defects, offering vast prospects for widespread application. Finally, the proposed method and device were experimentally applied in a practical engineering drainage tunnel to demonstrate their effectiveness and reliability.

This study delves into the diverse marine habitats of Jubilee Shoals, a submerged rocky reef off Pissouri Bay, Cyprus (eastern Mediterranean). The habitats include Posidonia oceanica meadows on the plateau, coralline communities on the vertical walls, and a cave system at its base. Utilizing closed-circuit rebreathers, trained cave divers quantitatively described the epibenthic communities and biodiversity within the cave system, ensuring both safety and high-quality data collection. Rebreathers allowed silent, bubble-less operation, efficient gas usage, extended dive times, reduced decompression times essential for detailed observation. The findings underscore the need for rebreathers in scientific exploration of deep-water environments, emphasizing their advantages. This approach facilitates undisturbed marine life observation and minimizes environmental impact, paving the way for future research and conservation in similar ecosystems.

AbstractThis chapter gives an overview of the basic principles for analysing material flows for production processes. This type of analysis is based on a calculation of materials going in and out of a process. Typical materials to be accounted for are energy, raw materials and other supporting materials. Likewise, outputs from a production process are waste of different types, emissions to air, water and soil, as well as noise, radiation, vibrations, and loss of heat. In an input-output analysis, the by-products from the process are also accounted for. The chapter also explains the principles of cleaner production starting with the motivation from corporate leadership to make production processes cleaner: to reduce waste and emissions and use material in a more efficient way. The concept of Cleaner Production (CP) also embraces strategic changes for making production and products cleaner and greener.

Abstract:
Understanding the impacts of traffic and climate change on water quality helps decision makers to develop better policy and plans for dealing with unsustainable urban and transport development. This chapter presents detailed methodologies developed for sample collection and testing for heavy metals and total petroleum hydrocarbons, as part of a research study to investigate the impacts of climate change and changes to urban traffic characteristics on pollutant build-up and wash-off from urban road surfaces. Cadmium, chromium, nickel, copper, lead, iron, aluminium, manganese and zinc were the target heavy metals, and selected gasoline and diesel range organics were the target total petroleum hydrocarbons for this study. The study sites were selected to encompass the urban traffic characteristics of the Gold Coast region, Australia. An improved sample collection method referred to as ‘the wet and dry vacuum system’ for the pollutant build-up, and an effective wash-off plan to incorporate predicted changes to rainfall characteristics due to climate change, were implemented. The novel approach to sample collection for pollutant build-up helped to maintain the integrity of collection efficiency. The wash-off plan helped to incorporate the predicted impacts of climate change in the Gold Coast region. The robust experimental methods developed will help in field sample collection and chemical testing of different stormwater pollutants in build-up and wash-off.&amp;nbsp;

Abstract:
The marine ecosystem, one of Earth's most vital and diverse environments, spans from sunlit surface waters to deep ocean trenches. It supports a vast array of life forms, from microscopic phytoplankton to colossal whales, and plays a crucial role in maintaining ecological balance and providing essential services for human well-being. Understanding and managing this complex system is critical, especially with increasing human impacts and environmental changes. Artificial intelligence (AI) has emerged as a transformative tool in environmental monitoring, revolutionizing the collection, processing, and interpretation of vast data related to natural systems. Environmental monitoring covers biodiversity, land use, air and water quality, and climate change indicators. Traditional methods, reliant on manual data collection and analysis, are costly, time-consuming, and limited in scope. AI enhances the efficiency, accuracy, and scope of these efforts, supporting more effective ecosystem management and conservation strategies.

Local governments in Bulgaria have stable property rights regulated by the Constitution (1991) and the Municipal Property Act (1996). Municipalities own and use different types of assets to provide public services to local communities, but the effectiveness of local financial management is a controversial and topical issue. This chapter aims to analyze the financial performance of 18 large municipal companies for the period 2006-2020 by applying the Z-Score model. The results show that most municipal companies achieve profitability while providing a wide range of public services, such as water supply and sanitation, garbage collection, maintenance of urban infrastructure, management of municipal markets, construction supervision, investor and technical control, property management, geodetic services, and security services. At the same time, the municipal companies that provide district heating and urban transport and operate the municipal sports complexes are in poor financial condition and need appropriate measures to improve their financial performance.

Abstract:
Abstract The water crisis affects the lives of millions over the world. Minimizing water losses in major water-consuming industries like power plants is of utmost importance. Since cooling towers lead to huge amounts of water loss, implementing modifications for recovering a fraction of this lost water in the exhaust has been a topic of active research. These modifications are often inspired by biological species, especially in arid regions, which have adapted in different ways by collecting water from fog, and hence biomimetic has become popular for water harvesting techniques.

As the size of a wind tunnel gets smaller, producing clouds with uniform properties becomes challenging because of 1) the reduced distance from the spray bar system to the test section and 2) the spray characteristics of most air-assisted nozzles used for spray generation.

Abstract:
Water is our most valuable natural resource, and is used to support the demands of industry, agriculture, hydroelectric power generation, and municipalities. Water also sustains Montana’s booming recreation and tourism economy and maintains the diverse freshwater ecosystems that provide natural goods and services and promote human well-being. As our population continues to grow, and the collective demand for water increases, it is imperative that we carefully assess how our water is used, as well as how changes in water distribution, management, and governance are likely to influence its avail

Abstract:
Visual inspection is the most used method to detect seepage at dams. Early detection can be difficult with this method, and use of appropriate real time monitoring could significantly increase the chances of recognizing possible failure. Seepages can be identified by analyzing changes in water and soil temperature. Optical fiber placed at the embankment’s downstream toe has been proven to be an efficient means of detecting real time changes at short intervals over several kilometers. This study aims to demonstrate how temperatures measured using fiber optic distributed sensing can be used to m

Chemical control of nuisance aquatic vegetation has long been the most widely utilized management tool due to its high level of efficacy, limited environmental impacts, and relatively low cost. However, unprecise application of herbicides can lead to uncontrolled invasive plants and unintended management costs. Therefore, precision herbicide delivery techniques are being developed to improve invasive plant control and minimize impacts to non-target plants.
