Abstract:
... Urban rivers have often experienced substantial engineering modification and consequently are highly degraded aquatic ecosystems with minimal riparian habitat. Habitat restoration and improvement efforts are needed within urban rivers to support ecological communities and increase ecosystem integrity. Most river restoration techniques are not feasible within large urban rivers, and so there is a n ...

Abstract:
... The managing and monitoring of natural and artificial river levees are crucial in order to reduce the hydrological risk. As these hydraulic structures are very extensive, the typically applied techniques (e.g. geotechnical soundings and visual inspections) provide only punctual information that are generally focused on areas already recognized as troublesome. To overcome these well-known issues, n ...

Abstract:
... Since the Neolithic, humans have gathered along coastal plains, where they had to face sea level rise and subsidence without the technology to oppose these processes. When sea level stabilized, approx. 6.000 yr. B.P., coastal colonization was allowed, but where mountain deforestation was carried out river sediment input increased tremendously: settlements were disconnected from the shore and harbo ...

Abstract:
... Considering the environmental issue due to waste oyster shells (WOS) dumped randomly and over-exploitation of river sand resources, a drive toward utilization of crushed WOS as substitution materials for fine aggregates mixed in concrete has been initiated. Waste oyster shells have been proved to have the potential to be recycled for use as construction materials. However, applying fine WOS aggreg ...

Abstract:
... Recycling of waste glass is an efficient way to protect the environment and save resources. This study evaluated the effective utilizations of glass sand (GS) to replace the quartz sand (QS) in typical ultra-high performance concrete (UHPC) and river sand (RS) in ultra-high performance river sand concrete (UHPRC). Ultra-high performance glass concretes (UHPGC) with different substitution ratios we ...

Abstract:
... In order to make hydropower station’s development and operation harmonious with ecological protection, the optimal operation of hydropower stations to meet the needs of ecological protection is studied. Firstly, the ecological protection function of river course is defined according to the minimum ecological runoff and suitable ecological runoff. Then, a multi-objective optimal running model of re ...

Abstract:
... In reflecting on the human domination of our planet in the Anthropocene, some have argued that concrete is among the most destructive materials created by humans. Here we explore this idea, specifically in the context of what we consider “the concrete conquest of aquatic ecosystems.” The ubiquitous use of concrete in transportation and building infrastructure has contributed to alterations in fres ...

Abstract:
... Physically based numerical models can predict scour depth at embankments located in bend reaches. However, methodologies for utilizing these numerical models to assess the risk of reinforced concrete embankment failure are rarely investigated. Therefore, a new assessment methodology is proposed to predict the riverbank failure caused by bend scour. The methodology is primarily based on a bend scou ...

Abstract:
... Although industrialization has raised the living standard of human beings but now it is also becoming threat to the environment. The manufacturing industries are producing waste material in large volumes and are emitting greenhouse gases. These waste materials are being dumped on open land that pollute the soil, water, and air. On the other hand, construction industry is using natural resources on ...
