Global warming, rising sea levels and rapidly growing cities are placing immense pressure on coastal cities, towns and subsistence communities. The U.S. Population Reference Bureau estimates that almost 6 billion people will be living within 200 kilometres of a coastline by 2025 – close to double the number in 2003. Population growth – along with sea level rise compounded by storm surges and increased rainfall intensity due to climate change – are the key reasons for the increase in coastal flooding and the degradation of our coastal regions and ecosystems today.

It is without question that the effects of human-derived underwater noise on marine life are receiving increased attention from scientists, regulators and the public. One of the core issues is the displacement of marine life from important areas due to behavioural responses to underwater noise from shipping, airguns and pile driving. Another issue is the impairment of hearing, which can be temporary (temporary threshold shift, TTS) or permanent (permanent threshold shift, PTS). Both effects can, at least in theory, lead to population-wide impacts to marine species. Continue reading “Agent-based modelling: Dynamic mapping of the movements of marine life”
It is a well-known fact that accidental oil spills can cause significant negative impacts on the environment – affecting ecosystems, bringing distress to marine life, damaging waterways, ruining infrastructure and economy, to name a few.
The 2010 Deep Water Horizon oil spill in the coastal waters of the Gulf of Mexico – often cited as the worst environmental disaster in the United States – saw up to 800,000 bird mortalities and approximately 60% decline in the number of laughing gulls along the Gulf coast between 2010 and 2013. Demands are therefore being placed on oil companies, service providers and environmental authorities to be prepared to take proper and efficient action, should an accident occur.

Defining its role in providing real customer value
The concept of the Digital Twin is increasingly entering the Water Sector as an innovation driver. More than ever, its role in bringing value to operators is being highlighted by industry professionals around the world.
What is a Digital Twin? A Digital Twin is a computer model that virtually reflects and simulates a real object, its environment and interaction, providing a picture as accurate as possible of how that object behaves in real time. This could be a water treatment plant, where the Digital Twin includes process models to simulate the treatment steps, physical assets (e.g. pumps) represented in CAD, and performance models to optimise resources (e.g. energy usage).
User experience design (often termed ‘UX’) is the process of creating products that provide meaningful, relevant and satisfying experiences to users. Most of you are likely to hear the term ‘UX Designer’ coming up more often nowadays. Just what does a UX designer do? Is this a ‘new’ thing? What’s the real background process of creating all these cool stuff?
Get up close and personal with our UX Designers Anna Katrine Høgh Andersen and Luca Mottadelli as they answer our 7 burning questions. Continue reading “7 questions for the User Experience designer”
Stormwater ingress to a city’s sewer system through low gully traps, illegal connections, broken pipes or unsealed manholes is known as Inflow and Infiltration (I&I). This can cause overflows, system strains and interruptions.
What is Inflow & Infiltration? Inflow: Stormwater that enters the wastewater network directly through gully traps, roofs or illegal connections. Infiltration: Stormwater or groundwater that enters the wastewater network through cracked pipes and leaky or faulty manholes.
Potential problems with insufficient water circulation in water tower tanks
Many would assume that water quality is best in the storage tank or near the tank. While that is often the case, there are exceptions where this might be the opposite. Continue reading “Is the darkest place under the candlelight?”
The rapid pace of development in coastal areas often comes at an environmental and ecological cost, with the accelerated loss of coastal nearshore habitats such as seagrass meadows and mangrove forests. However, the presence of these nearshore coastal habitats play an important role in the maintenance of resilience of coastal cities and populations. They confer resilience via ecosystem services such as carbon sequestration, moderation of natural hazards and nutrient cycling. There is a recognised and urgent need to stem the loss of these valuable habitats in balance with infrastructure development and economic needs.

Unsure about the similarities and differences between artificial intelligence, machine learning and deep learning? This blog post introduces the quick basics. Continue reading “The very basics of artificial intelligence, machine learning and deep learning”
A vast amount of the plastic that is produced for packaging purposes is used for storing food. Considering both the waste generated and the resources spent to produce packaging, it is only common sense to recycle some of this plastic for new food packaging. Moreover, circular economy is a focal point in the EU, and in 2025, the extended producer responsibility should result in more recycling. Continue reading “How to safely recycle plastic waste into new food packaging”
