Course Overview
This course presents risk assessment methods and concepts, many of which are required by USACE guidance. The objective is to enable participants to readily adapt these methods and concepts to their own studies and projects after successfully completing the course. Policy issues, concepts in statistical analysis, and risk and uncertainty methods used in the evaluation of flood risk management projects are emphasized in the course. Course workshops provide participants with the opportunity to apply the course's concepts using the Hydrologic Engineering Center Flood Damage Reduction Analysis (HEC-FDA) software program.

| Download the HEC-FDA Software (Brazil) | Last Modified: 2025-10-31 15:48:41.63 | Instructions page with a link for downloading the HEC-FDA software for use in the Brazil training class. |
| Ex1 1.8 Calculate EAD and AEP | Last Modified: 2025-11-03 09:13:22.801 | In this hands-on exercise participants will complete simple exercises to demonstrate how flood risk (expected annual damage) and other risk metrics are computed. |
| Ex2 3.8 Reduction in Consequences with Nonstructural Measures | Last Modified: 2025-11-06 08:04:44.382 | In this hands-on exercise course participants will calculate the reduction in consequences through the implementation of nonstructural measures for example residential and commercial structures. |
| Ex3 4.3 Incorporating System Response into Economic Risk | Last Modified: 2025-11-06 10:57:06.193 | In this hands-on exercise involves simple exercises to demonstrate how flood risk (expected annual damage) and other risk metrics are computed. |
| Ex4 5.1 Incorporating Reservoirs into Economic Risk | Last Modified: 2025-11-06 09:21:42.488 | In this hands-on exercise participants will complete simple exercises to demonstrate how flood risk (expected annual damage) and other risk metrics are computed. |
| Example Study Data for Brazil Class | Last Modified: 2025-10-29 09:44:17.671 | The purpose of this page is to provide a detailed list of the elements in the example study data and link to download the example dataset. The example data used in the HEC-FDA Version 2.0 Workshops is the same example study data provided in the HEC-FDA Version 2.0 Quick Start Guide. |
| WS1 2.7 Intro to HEC-FDA Software | Last Modified: 2025-10-29 10:27:07.911 | In this hands-on workshop participants are introduced to the HEC-FDA Version 2 user interface. Participants will become familiar with the Impact Area set importer, Terrain importer, and Properties editor. Participants will also import an HEC-FDA Version 1.4.3 model into the Version 2 software. |
| WS2 2.9 H&H Uncertainties | Last Modified: 2025-11-04 10:21:29.228 | In this hands-on workshop participants are introduced to HEC-FDA Version 2 to familiarize students with entering data for defining exceedance-probability and stage-discharge functions, and associated uncertainties. This workshop pertains to the Hydraulic data and frequency functions. |
| WS3 3.2 Economic Consequences with Uncertainty | Last Modified: 2025-11-05 06:57:03.359 | In this hands-on workshop participants use their previously generated HEC-FDA study files to compute and evaluate stage-damage relationships. |
| WS4 3.6 Without-Project Conditions | Last Modified: 2025-11-05 11:15:20.655 | In this hands-on workshop participants use their previously generated HEC-FDA study files to perform a without-project analysis for the Muncie, Indiana example study, including the computation and evaluation of expected annual damage and equivalent annual damage. |
| WS5 4.4 Levee Assessment | Last Modified: 2025-11-06 05:29:43.995 | In this hands-on workshop participants use their previously generated HEC-FDA study files to evaluate the economic feasibility and project performance of various levee alternatives. Participants recommend the “best" alternative. |
| WS6 5.1 Plan Formulation and Economic Evaluation | Last Modified: 2025-11-03 09:27:29.126 | In this hands-on workshop participants use the Muncie, Indiana example study data to create an HEC-FDA study from scratch to formulate and evaluate flood risk management alternatives. The workshop emphasizes formulation and evaluation of several flood risk management plans including levee, detention basin, nonstructural, combination detention basin and levee, levee and nonstructural, detention basin and nonstructural, and a plan with all the measures. |
