Welcome to the Hydrologic Engineering Center's web page for our life loss and direct damage estimation software, HEC-LifeSim. HEC-LifeSim is an agent based simulation system for estimating life loss with the fundamental intent to simulate population redistribution during an evacuation. Life loss and economic damages are then determined by the hazard (e.g. flooding).

The purpose of this site is to enhance the support services we provide to our customers. We've provided a number of resources here to help you download software, learn how to use HEC-LifeSim, resolve problems, report bugs, and suggest improvements to our products and service. Unfortunately, we are unable to provide phone or email technical support to non-USACE customers. However, we do encourage anyone who finds a “bug” in our software, to please report it through the Bug Report page of this website. Please review our Support Policy page for details.
