What is seawall? 


Best insight from top research papers

A seawall is a structure used for shore and slope protection in coastal areas. It can be made of concrete or gabions, which are steel fence-baskets filled with rocks or concrete blocks. Seawalls are designed to withstand high waves and provide stability to the shoreline. They can be used to protect off-shore platforms, wind power plants, bridge pillars, and other submarine structures. Seawalls can also be used as a fishing farm between the wall and the shore. They can replace conventional dikes and levees and assist in deep-sea mining. The design of seawalls can include features such as hanging triangular structures as surge stoppers and floating wave deflectors on the seaside of the wall.

What is the boundary layer?4 answersThe boundary layer refers to a thin layer of fluid that forms near a solid surface in a flow. It is characterized by large velocity gradients and plays a crucial role in determining drag and flow separation. The concept of the boundary layer was first introduced by Prandtl, who demonstrated its existence near rigid surfaces. The thickness of the boundary layer can be estimated and scaled with the inverse square root of the Reynolds number. The boundary layer can be laminar or turbulent, depending on the flow conditions. In the context of structural analysis, boundary layers are also referred to as regions of local compatibility bending near shell boundaries and changes in wall thickness. The study of boundary layers is important in various fields, including fluid dynamics, transport phenomena, and computational modeling.
What is the boundary layer?5 answersThe boundary layer is a region near a surface where the velocity of a fluid changes rapidly. It is characterized by large velocity gradients and plays a crucial role in determining drag and heat transfer in fluid flows. The concept of the boundary layer was first introduced by Ludwig Prandtl in the 1920s. The thickness of the boundary layer decreases with increasing Reynolds number and is inversely proportional to the square root of the Reynolds number. The boundary layer can be laminar or turbulent, depending on the flow conditions. In the context of linear transport theory, a boundary layer structure has been identified that governs the interactions between different materials or between a material and vacuum. Understanding and accurately modeling the boundary layer is important in various fields, including aerodynamics, heat transfer, and transport phenomena.
How do seawalls affect the livelihoods of coastal communities?5 answersSeawalls have various impacts on coastal communities' livelihoods. The presence of seawalls does not necessarily increase the value of protected homes, but it can negatively affect the value of neighboring properties in certain geographical areas. Seawalls also have implications for marine biodiversity, with sloping seawalls found to support greater coral communities compared to vertical seawalls. Additionally, the use of coastal resources by households is influenced by various factors such as climate and non-climate shocks, government policies, and livelihood diversification. The productivity of coastal and marine ecosystems can fluctuate due to environmental changes, leading to changes in resource extraction methods and the need for adaptation. Overall, the effects of seawalls on coastal communities' livelihoods are complex and depend on factors such as property values, biodiversity, and resource utilization.
What are the negative impacts of seawalls?3 answersSeawalls can have negative impacts on coastal communities and ecosystems. In terms of property value, the presence of seawalls does not necessarily increase the value of protected homes, and in some cases, it can actually decrease the value of neighboring properties. Seawalls can also adversely affect coral reef systems by altering fish assemblages and reducing feeding activity on the epilithic algal matrix (EAM). Additionally, seawalls are associated with reduced biodiversity due to their steep orientation and lack of microhabitats. In terms of community adaptation, poorly designed and constructed seawalls can lead to unintended negative outcomes, such as trapping water along their landward sides and compromising land and livelihood security. These findings highlight the need for careful consideration of the potential negative impacts of seawalls and the importance of site-specific adaptation measures that involve local perspectives.
What is the definition of offshore?3 answersOffshore refers to various concepts and practices across different domains. In the context of globalization, offshore outsourcing involves the movement of jobs to lower-wage countries, particularly in the service sector, and is often seen as a threat to jobs and economic security in higher-income countries. In the realm of property relations, offshore refers to regions where state oversight and regulatory rules are attenuated, such as in finance. Offshore can also refer to an offshore system for transferring fluid below sea surface, such as oil, using flexible transporting units and structure fix-points. Additionally, offshore is associated with international finance and the establishment of offshore financial markets and export processing zones, which have expanded rapidly since the 1970s. Lastly, offshore is viewed as a form rather than a place, with implications in offshoring finance and detention.
What is a sea salt?3 answersSea salt is a handmade food product that is obtained by evaporation of seawater in saltpans. It is a type of salt that is harvested from specific geographical regions, such as salt marshes, and is known for its distinctive physico-chemical characteristics. Traditional sea salt, including "flower of salt," is produced without washing, artificial drying, or the addition of anti-caking agents. Sea salt can contain organic compounds from its surroundings, and its volatile composition can vary depending on the location of harvest. Some compounds found in sea salt, such as carotenoid-derived compounds, can serve as potential volatile markers of sea salt. Sea salt production involves the evaporation of seawater in shallow pools called salterns, which can provide opportunities for fungal contamination. Finished sea salts have been found to contain viable fungi, including species that have the potential to cause food spoilage and may be mycotoxigenic.

How does REST API work in cloud systems?
5 answers
REST APIs play a crucial role in cloud systems by serving as the primary interface for software communication. They enable the interaction between different components of cloud architectures, such as software services, platforms, and infrastructure. RESTful APIs facilitate the transfer of representational state, leveraging the fundamental principles of the web to maximize its features. These APIs can be utilized to collect, process, and manage massive unstructured data efficiently within cloud systems. Additionally, efforts have been made to create a unified REST interface for various cloud data stores, ensuring extensibility, scalability, and high availability. Furthermore, advancements like Semantic OAS aim to enhance the description of RESTful services by semantically annotating API descriptions, making them understandable by both humans and machines.
Does traffic congestion decreases total output?
4 answers
Traffic congestion can indeed decrease total output. Congestion leads to delays, wasted fuel, and impacts on productivity, ultimately affecting drivers' utility and aggregate productivity negatively. Studies show that congestion can limit or reduce business sales, increase costs of delivery operations, and hinder scale economies in production processes, all contributing to decreased productivity. Research also indicates that traffic congestion can influence the efficiency of the production process, affecting Total Factor Productivity (TFP) growth and leading to indirect and long-term negative impacts on the regional economy. Therefore, the presence of traffic congestion can have detrimental effects on total output by impeding the smooth flow of goods, services, and people, thereby hampering economic activities and overall productivity.
