5. • Changes in Water Quantity and Quality
• Deteriorating Water Infrastructure at Risk
• Water Management in changing climate(s)
Examples of promising approaches to manage climate-related
water risks exist but the gaps between knowledge and
implementation remains a challenge –especially regarding
systemic, compounding and cascading risks

6. Cascading Consequences of
Heavy Rainfall for Urban
Systems
• In cities with combined sewer systems, storm
water runoff flows into pipes containing
sewage from homes and industrial
wastewater.
• Increase risk of exposure to waterborne
diseases and toxic chemical plant releases
• Closed roads and disrupted mass transit
prevent residents from going to work or
school and first responders from reaching
those in need. Source: EPA.

Critical Infrastructure Sector Impacts
Due to Drought Hazard
Existing resources from NIDIS, EPA, USDA, DOI, DHS, FEMA,
HHS-CDC, and other sources were compiled to create
a risk analysis of drought hazard impacts to critical
infrastructure sectors. The analysis reflects summaries of
identified vulnerabilities of critical infrastructure sectors
to direct exposure of drought hazards, operational impacts
to each sector that contributes to slow down or stoppage
of essential goods and services to meet demand needs,
and indirect/cumulative impacts of dependent sectors
and communities when supply needs cannot be met.
Ten critical infrastructure sectors and subsectors were
investigated in the context of five drought hazards.

Moulton Nigel, CA
• Aggressive menu of programs
• Conserve 5b litres per year
• Removed 0.5 mil+ m2 of turf
Las Vegas, Nevada
• Pay $300 per square metre
• 50 million litres saved/yr
• 18 m m2 of turf converted
• Set targets for resilience & reasonable
levels of use
• Go big on investing in efficiency and reuse

17. • Long-term and sustained observation programs are
critical, especially for model verification. Without
some degree of verifiability, hard to expect their use
What is the message……..
……..in the context of a changing climate?
Sorooshian, Lall, Pulwarty and others…..
• Despite advances to date, predicting future hydro-climate
variables precisely will remain a major challenge
• Nature is complex and observing and modeling its nonlinear
behavior is very challenging. Esp. reliability of high resolution
information “generated” by models.
tFactoring in resiliency in water resources
system’s design and planning is still the
safest approach
