LWI Region 3 Modeling Overview

5 Consequence Modeling

5.1 FLOOD IMPACT ASSESSMENT USING GO CONSEQUENCE SOFTWARE The risk assessment comprises three main components—threat, vulnerability, and Consequence Modeling (Figure 5-1).

Consequence Modeling quantifies the potential socioeconomic impact on a system following an event. It is most often performed in support of cost-benefit and cost-effectiveness analyses in project evaluation tasks. While it is, in principle, possible to model all consequences of a flood event, this initiative focuses on: 1. Identifying the number of affected structures, and 2. Quantifying the direct economic damage to structures within the Louisiana state regions.

In this context, the cornerstone of the Consequence Modeling process is the use of depth-damage functions developed by FEMA and USACE. Consequence Modeling was performed using Go Consequence, a script-based tool designed by USACE and The Water Institute to process extensive flood data and structural inventories efficiently. That Consequence Modeling is complemented by the Hydrologic Engineering Center-Flood Impact Analysis (HEC FIA) as a validation tool, ensuring accuracy and replicability in estimating potential damage.
