Green infrastructure can help reduce stormwater runoff and combined sewer overflows in Syracuse. Examples of green infrastructure include green roofs, rain gardens, bioswales, rain barrels, and permeable pavement. Incorporating green infrastructure into Syracuse's existing gray infrastructure for stormwater management can help reduce flooding, improve water quality, and lower costs compared to relying solely on traditional pipe and treatment systems. Case studies from cities like Chicago, Portland, and Toronto demonstrate the multiple benefits of green infrastructure approaches.
Blue and Green Cities The Role of Blue-Green Infrastructure in Managing Urban...Robert Brears
This book offers new research on urban policy innovations that promote the application of blue-green infrastructure in managing water resources sustainably. The author argues that urban water managers have traditionally relied on grey infrastructural solutions to mitigate risks with numerous economic and environmental consequences. Brears explores the role urban water managers have in implementing blue-green infrastructure to reduce ecological damage and mitigate risk. The case studies in this book illustrate how cities, of differing climates, lifestyles and income-levels, have implemented policy innovations that promote the application of blue-green infrastructure in managing water, wastewater and stormwater sustainably to reduce environmental degradation and enhance resilience to climate change. This new research on urban policy innovations that promote the application of blue-green infrastructure in managing water resources sustainably will be of interest to those working on water conservation and policy.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

3. What is Green Infrastructure?
Green Infrastructure refers to the ecological processes, both natural
and engineered, that act as living infrastructure. Green Infrastructure
elements are planned and managed primarily for stormwater control,
but also exhibit social, economic and environmental benefits.

A street that uses vegetated facilities to manage stormwater runoff at its
source is referred to as a Green Street.
A Green Street is a sustainable stormwater strategy that meets regulatory
compliance and resource protection goals by using a natural systems
approach to manage stormwater, reduce flows, improve water quality and
enhance watershed health. www.portlandonline.com
18. Stormwater Issues
- Surface Run-off and Water Pollution in Urban Environment

Urban impervious surfaces generate extraordinary stormwater
run-off, which brings various pollutants from urban environment
to sewer system and may discharge directly into streams, rivers
and lakes as overflow.
19. Stormwater Issues - CSO
Combined sewer systems are
sewers that are designed to
collect rainwater runoff,
domestic sewage, and industrial
wastewater in the same pipe.
Combined sewer systems are
designed to overflow
occasionally and discharge
excess wastewater (Combined
Sewer Overflow) directly to
nearby streams, rivers, or other
water bodies.
637 milion gallons of untreated
combined sewage in Syracuse
is currently discharged per year
into Onondaga Lake. (CH2M HILL)
Combined Sewer System www.ongov.net
20. Stormwater Issues - CSO
In 1998, under an Amended
Consent Judgment (ACJ),
Onondaga County began to
abate combined sewer
overflows (CSO) from
impacting tributaries that enter
Onondaga Lake by using
traditional methods of
conveyance pipes and
treatment facilities (gray
infrastructure).

In the past few years in Onondaga County near Midland RTF (June 2006)
Over 13 sewer separation projects were completed

The green infrastructure techniques are not supposed to solve the
stromwater problems single-handedly.
However, incorporating green infrastructure into stormwater
management system can delay and reduce the volume of "peak
flow“, which will consequently reduce the CSO volume and make the
gray infrastructure more workable.
