Overview

Viewing inundation modeling results, community characteristics, and infrastructure data together in 

a single geographic information systems (GIS) mapping platform allows emergency managers, dam 

owners and operators, flood plain managers, engineers, planners, and other community partners to 

conduct risk- and data-informed community analyses for improved planning and response 

operations. 

This guide explains how to add inundation map results from the Decision Support System for Water 

Infrastructure Security (DSS-WISETM) Lite into the Resilience Analysis and Planning Tool (RAPT) to 

visualize and assess the unique population characteristics and infrastructure location features within 

the forecasted inundation area. 

This integration will help users better understand the consequences their community partners may 

face as a result of a dam-related incident. Modeling results become more actionable by clearly 

establishing vulnerable population and infrastructure contexts when assessing the potential impacts 

of an operational action or dam-related incident. Finally, the visual nature of this type of product can 

facilitate communication with decision makers and support outreach to community partners.

FEMA supports using modeling tools like Decision Support System for Water Infrastructure Security

(DSS-WISETM) Lite, with its Human Consequence Module (HCOM), in combination with RAPT, to help 

engineers, planners, dam owners, and emergency managers better understand their risk landscape 

and the potential consequences of dam-related incidents. This user guide provides instructions for 

integrating DSS-WISETM Lite results with RAPT for further analysis. The guide assumes a working 

knowledge of DSS-WISETM Lite, ArcGIS, RAPT, and related terminology. It is not meant to be tutorial 

on how to use these capabilities.

1. Decision Support System for Water Infrastructure 

Security (DSS-WISETM) Lite 

DSS-WISETM Lite is a web-based, automated two-dimensional modeling and mapping capability 

developed by the National Center for Computational Hydroscience and Engineering (NCCHE), the 

University of Mississippi. DSS-WISETM Lite allows users to quickly set up dam-break/ levee-breach

flood inundation simulations with minimum user input data. In addition, DSS-WISETM Lite Human 

Consequence Module (HCOM) provides analysis of People at Risk (PAR) by combining the results of 

flood simulation using DSS WISETM Lite with a population data set. 

Figure 1. DSS-WISETM Lite Homepage

DSS-WISETM Lite provides maps of maximum flood depth, flood arrival time, flood hazard risk for 

people caught outdoors and indoors, and the potentially lethal flood zones (PLFZ) for children and 

adults. DSS-WISETM Lite geospatial files are compatible with most GIS software and easily imported 

into other analysis tools including RAPT. FEMA fact sheets provide more information on DSS-WISETM 

Lite and HCOM. 

DSS-WISETM Lite is a free-of-charge system available 24/7 to FEMA, state dam safety offices, and 

federal and state stakeholder agencies, but requires users to register and obtain approved access.1

1 To request access to DSS-WISETM Lite, click the green Click to Request Access button on the DSSWISETM Web homepage 

and fill out the “New User Registration” form. 
Integrating DSS-WISETM Lite Results into RAPT

Users are required to apply for access to a specific user group(s), based on geographical location or

agency affiliation. Local group managers, approved by FEMA, have the authority to approve or deny 

all new users. The capability is accessible to registered users via the web portal DSSWISETM Web. 

2. Resilience Analysis and Planning Tool (RAPT) 

RAPT is a free GIS web map that allows federal, state, local, tribal and territorial emergency 

managers, planners, and other community leaders to visualize and examine the interplay of census 

data, infrastructure locations (e.g., fire stations, hospitals, schools, etc.), and hazards, including realtime weather forecasts (including extreme precipitation), historic disasters and forecasted climate 

risk (e.g., sea level rise). RAPT also includes a broad range of population and community 

characteristics that can assist with defining and describing the PAR, such as demographics, housing 

data, and social factors. 

RAPT does not require a registration or login for access and is available at 

https://www.fema.gov/RAPT, along with video tutorials and other resources.

Getting Started 

1. DSS-WISETM Lite Results Files

DSS-WISETM Lite simulations are 

run by trained and registered 

users. Once the user runs a 

simulation, results are available

for viewing and downloading (as 

compressed, or zip, folder) from 

the Status & Results page. 

The results package follows a 

naming convention such as

“9999_All_Files_ Simulation.zip.” 

If HCOM was also run, a second 

zipped folder will be created 

using a similar naming 

convention of 

“9999_All_Files_HCOM.zip.” 

 Figure 3. Downloaded Files

In this naming convention, the numeric at the beginning of the file name references the ID of the 

simulation run in DSSWISETM Web. 

Figure 4. Compressed ZIP Files

Once downloaded and unzipped, the results package contains various shapefile folders that can be 

imported into RAPT for analysis with community datasets. Shapefiles are a data storage format for 

storing the location, shape, and attributes of geographic features. For dam incident planning, two 

particularly useful layers for analysis include:

• Maximum Depth Polygons – Shapefile containing polygons of maximum depth intervals. 

• Arrival Time Polygons – Shapefile containing polygons of arrival time intervals.

The HCOM layers offer further insight into flood risk and emergency planning and include: 

• HCOM Hazard Level to People Outdoors – Shapefile containing polygons of hazard levels to 

people caught outdoors in the flooded extent.
Integrating DSS-WISETM Lite Results into RAPT

6 

• HCOM Hazard Level to People Indoors – Shapefile containing polygons of hazard levels to 

people caught indoors in the flooded extent.

• HCOM Potentially Lethal Flood Zones

– Shapefile containing polygons of 

flood zones potentially lethal to 

adults and children.

For a full list of folders contained in the

results package, please visit DSSWISETM Web. 

 Figure 5. Unzipped Files

Each individual folder represents a single shapefile and contains several different files. These files 

cannot be used independently of one another and must remain grouped at the same folder level to

be read into a GIS application or uploaded into RAPT. Note: The folder must contain at least three 

files (although others may be included): dbf, shp, and shx. After folder contents are confirmed to 

contain the appropriate files, it can be read using GIS or uploaded directly into RAPT. 

2. Preparing DSS-WISETM Lite Results for Input into 

RAPT 

DSS-WISETM Lite results shapefiles use a simple, monotone symbology (i.e., how each layer visually 

looks on the map). Although not necessary, to make the results more visually informative, the

different contour layers can be symbolized with distinct colors using any GIS application. Shapefiles 

are then uploaded as a hosted feature service to URLs for importing into RAPT.2 The section walks 

through the steps for opening and symbolizing the flood arrival time and flood height max output 

layers with color using ArcGIS. Information on colorizing HCOM layers is also provided.

2.1. Symbolizing the GIS Output using ArcGIS

ArcGIS is a GIS mapping and spatial analytics software developed and maintained by Esri. ArcGIS is a 

subscription-based service; however, free public accounts are available for noncommercial use.

More information about ESRI and ArcGIS are available at https://www.esri.com/en-us/home. 

The instructions provided for opening and symbolizing the shapefiles for DSS-WISETM Lite results are 

for ArcGIS for Desktop 10.8. However, the directions will not be substantially different for any 10.x 

version of ArcGIS for Desktop. Directions may vary for earlier versions of the application. 

2 For users that do not want to colorize DSS-WISETM Lite results, do not have access to ArcGIS Online, or are using the local 

“File” option for adding data into RAPT, please skip directly to the next section entitled “IMPORTING DSS-WISETM LITE 

RESULTS INTO RAPT.”

To symbolize the shapefile output layers and make the results more visually informative:

1. Open a blank ArcMap document by clicking on the New button, or choosing “New” from the File

menu. 

2. Click on “New Maps,” chose the “Blank Map” option, and then click the “OK” button.

Figure 6. Blank Map Option Process

3. Click on the Add Data button and choose “Add Data.” (Note: Toolbars may be located in different 

areas of the screen.) 

4. Navigate to the folder that contains the shapefile output layers.

12. Click on the “Add All Values” button to add in all of the different attributes for the layers. 

Figure 13. Add All Values Process

13. For the flood arrival time and flood height max layers, change the “Color Ramp,” as suggested 

and click “OK.” (Note: Recommended “Color Ramp” options help differentiate the DSS-WISETM 

Lite results from each other and distinguish them from data layer colors used in RAPT.) 

Figure 14. Color Ramp and Color Range Examples
Integrating DSS-WISETM Lite Results into RAPT

2.2. Viewing Colorized Shapefile Layers

The results shapefile layer(s) should now be symbolized in the map viewer according to the “Value 

Field” and “Color Ramp” chosen. The “X” marks the dam’s location. For the flood height max layer, 

the values correspond to the flood’s maximum height in feet in a given area. For this example, the 

inundation height is up to 30 feet, with the maximum depth occurring closest to the dam. 

Figure 19. Flood Height Max (feet)

For the flood arrival time layer, the values correspond to the hours post dam breach that the flood 

Figure 20. Flood Arrival Time (hours)
Integrating DSS-WISETM Lite Results into RAPT

16

will arrive in each area. For this example, “0.25” equates to a quarter of an hour, or 15 minutes, 

which occurs closest to the dam. The highest value “4.04” equals to a time of just over four hours 

until the flood arrives at that given spot. 

For the HCOM Potentially Lethal Flood Zones layer, the values correspond to the areas potentially 

lethal to adults and children based on the speed and depth of the flood water. For this example, 

nearly all of the inundation area is lethal to adults (and children). Just a few small sections are lethal 

to only children (who are susceptible to lower depth and velocity thresholds because to their smaller 

size). 

Figure 21. HCOM Potentially Lethal Flood Zones

For the HCOM Hazard Level to People Indoors layer, the values correspond to the potential danger 

associated with the collapse of different buildings based on the speed and depth of the flood water. 

For this example, building types range from poorly constructed units (e.g., mobile homes) to timber, 

brick (i.e., masonry), and concrete construction. In general, all structures, including large concrete 

structures, are at high risk closer to the dam; poorly constructed buildings are also risk further 

downstream.
Integrating DSS-WISETM Lite Results into RAPT

17 

Figure 22. HCOM Hazard Level to People Indoors Map

For the HCOM Hazard Level to People Outdoors layer, the values correspond to the potential danger 

level (or hazard category) for people caught outdoors. In general, very low hazard corresponds to 

shallow flow or deep standing water. Low hazard is dangerous to only children. Moderate hazard is 

dangerous to some adults, while high hazard is dangerous to most adults. Finally, extreme hazard is 

considered dangerous to all people caught outdoors. For this example, most of the flood inundation 

area is considered extremely high hazard.

2.3. Saving and Uploading to ArcGIS Online

Save the map project in .mxd format to 

maintain shapefile symbology for future 

reference. Click on the File menu and 

choose “Save As.” Set the location where 

the map document will be saved, choose a 

name, and click “Save.” Note: For easy 

reference, choose a file location and name 

that aligns with the original naming 

convention the DSS-WISETM Lite output file.

Recommended practice is to save individual 

layer files because each DSS-WISETM Lite

simulation run is a unique scenario. Figure 24. ‘Save As’ Option under File Tab

Therefore, the values in the UBOUND and LBOUND fields, respectively, will change with each 

scenario. 

To bring map layers into RAPT 

while retaining colorized 

symbology, shapefiles must be 

uploaded as a hosted feature 

service to ArcGIS Online (to make 

them URLs). For instructions on 

uploading and hosting a feature 

service on ArcGIS Online, see 

Publish to ArcGIS Online and 

ArcGIS Enterprise on the Esri 

website. This opton uses Esri’s 

ArcGIS for Desktop or ArcGIS Pro 

to publish a hosted feature 

service.3 

 Figure 25. ‘My Maps’ Folder Example

3 Although non-Esri GIS applications exist (i.e., QGIS), there is no direct connection from these to ArcGIS Online.

Importing DSS-WISETM Lite Results 

into RAPT 

1. Adding Modeled Inundation Data Layers

The Add Data tool, located in the navigation tool bar on the top right-hand side of the RAPT 

application window, allows users to add modeled inundation data layers to the interactive map. 

Figure 26. ‘Add Data’ Icon on Toolbar

Users can add data using two methods: URL data source or local file. Note: Only the “URL” option (as 

shown at the end of the previous section) will retain the colorized symbology set previously using 

ArcGIS; the “File” option will apply the default simple, monotone symbology. However, even though 

colorized maps are more visually informative, the results are the same and RAPT analysis tools are 

available on either map type. 

Once uploaded, RAPT will show the modeled inundation data layers on the map and will list the 

inundation layer on all Layers lists. For easy identification, the beginning part of the layer name will 

match the original file name.

RAPT only allows the temporary addition of DSS-WISETM Lite layers and they will no longer appear

whenever the browser window is refreshed or closed. As RAPT is a nationally available GIS tool, 

added layers cannot be saved to the map and retained for future review. However, users can re-load 

DSS-WISETM Lite layers at any time using the Add Data tool. 

1.1. URL Data Source

In order to bring DSS-WISETM Lite map layers into RAPT 

while retaining colorized symbology, shapefiles must 

be uploaded as a hosted feature service to ArcGIS 

Online. Online data is added by entering the data 

source URL using the “URL” option in the Add Data

tool window and clicking the “Add” button. The 

shapefile will then be populated within the web 

application using the color symbology set previously 

using a GIS application.

 Figure 27. Add Data Tool URL
Integrating DSS-WISETM Lite Results into RAPT

20 

Figure 28. RAPT Map Example Highlighted in Orange and Yellow

1.2. Local File

Users can upload GIS layers directly from a user’s hard 

drive through the “File” option. Before uploading, 

compress shapefiles into individual zip files. Drag and 

drop the zipped shapefile directly into the Add Data tool 

window, or chose the file manually using the “Browse” 

feature. The shapefile will then be populated within the 

RAPT web application using the default simple, 

monotone symbology. It will not retain any color 

symbology set previously using the ArcGIS application.

 Figure 29. Add Data Tool 

Figure 30. RAPT Map Example Highlighted in Blue

21 

2. Adjusting DSS-WISETM Lite Layer Appearance 

Once uploaded into RAPT, the DSS-WISETM Lite modeled inundation data layers default to the top of 

the Infrastructure Layers list. RAPT displays layers on the map hierarchically; layers toggled on that 

are listed higher on the drop-down layer list will be shown on the map on top of those that are listed 

lower down. Thus, it may be necessary for users to adjust the layer transparency to view multiple 

layers more clearly. 

To adjust the transparency of any layer:

1. Click on the Infrastructure icon, then click on the three dots next to the layer name and select 

transparency. 

Figure 31. ‘Infrastructure’ Icon on Toolbar 

Figure 32. Infrastructure Tool Example

2. Click on the data layer checkbox next to any infrastructure layer name (e.g., “Flood_Depth_MaxFlood_HMax_Contour_in_ft” for the DSS-WISETM Lite modeled flood height max), then click on the 

three dots next to the layer name and select transparency. 

3. The slider allows users to adjust the transparency as needed. 

4. The order of the layers can also be changed using the “Move up” and “Move down” options. The 

selected layer listed higher in the drop down layer list will show on the map on top of layers lower 

on the drop down list.

1. Infrastructure Data

Community infrastructure data layers (listed below) pull information from the Homeland 

Infrastructure Foundation-Level Data (HIFLD) Subcommittee. The HIFLD Open data portal contains 

national foundation-level geospatial critical infrastructure data in the public domain. HIFLD Open can 

be accessed at https://hifld-geoplatform.opendata.arcgis.com/.

Infrastructure data can be added to and visualized on the map, as well as downloaded using the 

attribute table. To turn on the various community infrastructure data layers, click on the 

Infrastructure icon. Then select the box next to the layers of interest and the data points will appear 

on the map. For more information on how to use the infrastructure data, please refer to the RAPT 

User Guide available online at www.fema.gov/rapt.
Integrating DSS-WISETM Lite Results into RAPT

23 

Figure 33. RAPT Map with Infrastructure Points Highlighted Example

For a modeled dam incident, the user can view and identify the various community assets that may 

be at risk because they exist within, or near the boundary of, a flood inundation area (based on a 

specific DSS-WISETM Lite simulation run). For this example, flood arrival time indicates that 

floodwater will reach two private schools, a Fire station, and one place of worship within about one 

hour of the dam incident. Within approximately three hours, floodwaters will also inundate a nursing 

home, a major highway, and another Fire station further downstream. Additionally, there is a public 

school, private school, nursing home, and two pharmacies on the edge of the inundation area. 

Figure 34. RAPT Map Emphasizing Infrastructure Points Example
Integrating DSS-WISETM Lite Results into RAPT

24 

Note: To access additional information on any facility or community assets, click on a data point and 

a pop-up box will appear with available information (from HIFLD Open). For example, nursing homes 

and hospitals list number of beds at each facility; schools include grade levels, student enrollment, 

and number of teachers.

Looking at the flood height max layer, all the identified community assets within the dam inundation 

area will experience between one to six feet of flooding. Assets on the edge may additionally be at 

risk of minor flooding. Multiple roadways will also be affected by floodwater.

Figure 35. RAPT Map with the ‘Flood Height Max’ Layer Example

2. Resilience Indicators 

RAPT includes several resilience indicator layers that researchers have used to identify and quantify 

characteristics that make a community more resilient to disasters. These indicators fall into two 

different buckets: population-focused indicators and community-focused indicators. Many of the 

resilience indictors are available at both the county and census tract level.

To turn on the various resilience indicator layers, click on either the County Indicators or Census 

Tract Indicators icon located in the navigation tool bar on the top right-hand side of the application 

window. Then select the box next to the layers of interest and the data points will appear on the map.

Figure 36. ‘County’ Indicators and ‘Census Tract’ Indicators on Toolbar
Integrating DSS-WISETM Lite Results into RAPT

25 

Figure 37. Community Resilience Indicators Page

For more information on how these indicators were chosen, please refer to the Community 

Resilience Indicator Analysis Report available on the web at www.fema.gov/rapt. 

For a modeled dam incident (based on a specific DSS-WISETM Lite simulation run), the user can view 

resilience indicator layers to help identify at risk populations located within, or near the boundary of, 

a flood inundation area that may need additional outreach before and/or extra assistance during a 

dam incident. In this example, the area north of the inundation zone includes three census tracts 

with larger percentage of individuals over the age of 65 (at around 30 percent of the population).

Figure 38. RAPT Map Showing Census Tract Indicators Example
Integrating DSS-WISETM Lite Results into RAPT

26 

Note: Clicking on any census tract area will bring up a pop-up box with county-level summary 

information for all resilience indicator (page 1) and detailed census-tract data for the specific 

resilience indicator chosen (page 2), including a comparison to the overall U.S. population data. 

Figure 39. Census Tract Area Tool and County Summaries Examples

Alternately, the area south of the inundation zone includes three census tracts with a greater 

percentage of individuals with limited English proficiency (ranging from about 7 to 12 percent).

3. Incident Analysis Tool

The Incident Analysis Tool allows users to draw a shape around an incident or area of interest (single 

point, linear, and polygonal) and identify and visualize infrastructure entities within this zone. This 

tool can provide a comprehensive list and visuals of the locations of infrastructure entities within the 

buffer zone. 

The Incident Analysis Tool is in the navigation tool bar on the top right-hand side of the application 

window (users may need to click the “more” icon in the upper right to find the tool). The tool will open 

at the bottom of the page. For more information on the Incident Analysis Tool, please refer to the 

RAPT User Guide available online at www.fema.gov/rapt. 

Figure 41. ‘Incident Analysis’ on Toolbar

The polygon option can draw a rough outline around the modeled inundation area. The Incident 

Analysis Tool can set a buffer distance4 of 1 mile or more. In this example, there is a 1-mile buffer 

zone around the drawn polygon. This extended buffer zone can help users identify additional 

community assets that may be at 

risk and/or support for emergency 

planning activities (e.g., 

establishment of evacuation and 

shelter-in-place zones). 

 Figure 42. Incident Analysis Tools Options

In this example, the inundation area buffer zone of 1-mile contains a total of six nursing homes, 20 

schools, six fire stations, and nine pharmacies. Clicking on the specific infrastructure group name 

along the bottom bar allows the user to view additional information on each of the various assets or 

facilities within each infrastructure group as well as allows the user the option to download the 

information. 

4 The buffer distance can range from 1 to 100 miles. The initial default is set at 10 miles. To change this value, use the 

slider or type in the desired value in the box. 
Integrating DSS-WISETM Lite Results into RAPT

Figure 43. RAPT Map Highlighting 1-Mile Buffer Zone

Note: The user must add the Infrastructure layers to the map before running the Incident Analysis 

Tool. Clicking on the Infrastructure icon after the tool is used will cause the delineated buffer zone to 

disappear.

4. Population Counter Widget

The Population Counter allows users to draw a specific shape on the map (e.g., circle, rectangle, 

polygon etc.), select all the census tracts within or touching that shape, and calculate the estimated 

population of individuals with specific resilience 

indicator characteristics (e.g., age over 65, 

disability, unemployment, etc.) in those selected 

census tracts. This tool can provide a visual of all 

census tracts that touch the shape, as well as the 

estimated total number of individuals with the 

chosen indicator characteristic.

The Population Counter is located in the 

navigation tool bar on the top right-hand side of 

the application window (users may need to click 

the “more” icon in the upper right to find the tool). 

The tool will open at the bottom of the page. For 

more information on the Population Counter, 

please refer to the RAPT User Guide available 

online at www.fema.gov/rapt. 

 Figure 45. Select Indicators Tab Example

Figure 46. ‘Population Counter’ on Toolbar

In this example, the widget can create a rough outline around the modeled inundation area. Then the 

user can choose any indicator of interest from the drop-down list and click the “Run” button. The 

Population Counter provides the population estimates (based on census tracts) for select subpopulations that may need additional outreach before and/or extra assistance during a dam incident 

because they are located within, or near the boundary of, a flood inundation area (based on a 

specific DSS-WISETM Lite simulation run). Examples of these populations include the number of 

individuals over the age of 65, with a disability, limited English proficiency, or no personal vehicle.
