U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA Slide 1 Energy & Infrastructure Analysis Infrastructure Interdependency Modeling and Simulation – Examines how infrastructure systems interact with one another and how disruptions in one infrastructure can propagate among infrastructures – Natural and terroristic events – Tools developed for varying levels of fidelity

U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA Slide 2 Multi-Hazard Infrastructure Impact Assessment (MHIIA) Flood Hazard Models – One-dimensional models – Two-dimensional models – Cellular Automata (CA) – Step up from “Naïve” Existing inundation maps – E.g., FEMA, NOAA/NWS Hazard Events/Modeling IND Earthquake Flood Chem/Bio Etc.

U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA Slide 3 Hazard Events/Modeling Direct Effects (Fragility) IND Earthquake Flood Chem/Bio Etc. Infrastructure databases Fragility curves Secondary Effects (Infrastructure Models) Electric power Water Economy Telecomm Public health Etc. Multi-Hazard Infrastructure Impact Assessment (MHIIA) Extraction of assets from many sectors and mapping of damage probability very quick

U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA 4 Interdependency Environment for Infrastructure Simulation Systems (IEISS)- A Flexible & Extendible Software Framework designed for: Modeling Simulating Analyzing Multiple Interdependent Infrastructures – i Objective – identify and understand interdependencies – s Importance – study complex, emergent, cascading behaviors Value – understanding system behavior; capturing cascading effects; analyzing “what- if” scenarios Infrastructure Secondary Impact Analysis

U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA Case Study: Bay Area Sea Level Rise Inundation Event USGS inundation map (Knowles 2008, used in Heberger et al. 2009) Sea level rise at 0, 50, and 100 centimeters using MSL and 100-yr event Infrastructure Impact Assessment Infrastructure Identification MHIIA (Electric power, hospitals, wastewater facilities) Cascading Impact IEISS (Electric power only) Questions: How many substations are inundated and what are the impacts (e.g., outage area and population)? How many hospitals and wastewater facilities are inundated and what are their capacities? Slide 5

U N C L A S S I F I E D Operated by the Los Alamos National Security, LLC for the DOE/NNSA Conclusions Inundation related infrastructure impacts from sea level rise alone are minimal – Flood events on top of sea level rise must be considered – Upstream tributary impacts should be investigated – Accountancy of changing morphology due to sea level rise induced erosion Framework can be used in planning – Many scenarios quickly for many sectors – Local to regional scale Slide 14
