15.1 Tsunami modeling and inundation mapping for Greater Victoria

Presented By: Mike Brady, AECOM Canada Ltd.
Time: Tuesday, 2:00 - 2:30 PM

AECOM, in collaboration with Applied Research International LLC, provided consulting services for modeling of tsunami run–up elevations and inundation limits for the entire coastline of the Capital Regional District (CRD), located at the south end of Vancouver Island in British Columbia, Canada.

A magnitude Mw 9 earthquake in the Cascadia subduction zone may occur in the future and tsunami waves are predicted to propagate and resonate along the Strait of Juan de Fuca with a risk that waves and run-up along coastlines within the CRD could result in human injury and death as well as extensive damage to infrastructure.

The current mapping for the CRD tsunami wave height and run-up is based upon models developed in 2004; however, recent experiences, including the 2011 tsunami in Japan showed that older models might not be reliable predictors.

The tsunami model NEOWAVE (Non-hydrostatic Evolution of Ocean Wave) was used to model tsunami wave generation at the source and inundation along the coastlines of the CRD, as well as the US Olympic Peninsula, San Juan Islands and parts of Puget Sound. NEOWAVE is approved by the National Tsunami Hazard Mitigation (NTHMP) for use in development of tsunami evacuations maps and has been adopted by a number USA coastal areas and states.

This presentation will provide the objectives, methods, and findings of the work, which included colour-coded maps showing water level, velocities and tsunami arrival times as well as a Tsunami Hazard Line completed for the entire CRD coastline that will be used by public safety professionals for emergency planning.

15.2 Earthquake resiliency/emergency preparedness of the City of Vancouver's water system

Presented By: Michael Irvine, City of Vancouver.
Time: Tuesday, 2:30 - 3:00 PM

The earthquake hazard in Southwest BC represents a clear and present danger. Scientists who have devoted a lifetime to studying the Cascadia Subduction Zone suggest that a significant earthquake event is inevitable. After recent earthquake events in Chile, Japan, and New Zealand devastated urban and coastal communities alike, the City of Vancouver recognized the need to better understand the earthquake risk, the current state of resilience across the city and plan to address the gaps. This presentation will summarize some of the efforts of the City of Vancouver's Waterworks department to improve both the resiliency of its water system and its ability to respond to emergencies of all kinds. Such efforts include the development of a long-term hardened grid for the City's water system, a trial installation of earthquake resistant ductile iron pipe (ERDIP) and the development of emergency response scenarios to prioritize the delivery of water supplies to critical facilities such as hospitals.

15.3 Protecting and utilizing SCADA during emergency situations

Presented By: Zane Spencer, MPE Engineering Ltd.
Time: Tuesday, 3:00 - 3:30 PM

SCADA (Supervisory Control And Data Acquisition) systems are utilized throughout the water and wastewater industry to monitor and control water treatment, water distribution, wastewater collection and wastewater treatment infrastructure.

During emergency events, especially natural disasters, critical infrastructure systems become a vital part of our response plans. SCADA systems can provide valuable information to responders as well as Utility owners who are tasked with maintaining these systems during emergencies. Failure of critical infrastructure systems during emergency events can lead to lack of water for firefighting purposes, public health concerns related to contaminated potable water systems and sewage contamination in flooded areas.

This presentation will discuss some of the common steps, which can be taken to safeguard a SCADA system from failure when it is needed most. Common failure points will be identified along with possible mitigations. Additionally the use of SCADA as a tool in an Emergency Operations Centre will be discussed to provide rationale for integrating SCADA systems with emergency preparedness and response planning.
