Environmental Data and Model Catalog (EnDMC)

Welcome to Louisiana Watershed Initiative’s (LWI’s) EnDMC (pronounced like “endemic”), which simplifies the management and discovery of environmental data and models. EnDMC was created to achieve the LWI’s model use, storage, and maintenance initiatives, by helping users identify relevant models and data. This application will allow you to:

• Create metadata for the model, simulation, and/or (non-model) dataset you want to include in the repository;
• Upload the digital assets associated with your metadata entry; and
• Search and download the model, simulation, and/or dataset files you need.

In order to use most of the functionalities of the repository, you need to register or login if you have an existing account.

All users can search and download models and simulations filed. To create metadata and upload the digital assets associated with it, you need an editor role. This can be requested in the registration form and can be approved by an administrator.

This application is currently under development. Please provide us with any feedback via this survey that would help us improve your user experience. For general questions or more in-depth feedback, please contact us at endmc@thewaterinstitute.org.

Accessing Terrain Files

Terrain files from the LWI HEC-RAS calibration/validation and design storm runs are available in dedicated subfolders to make them easier to find.

To download the terrain files, you need:

• Locate the desired model application and open its metadata page.
• Scroll to the bottom of the page to access the model files.
• Navigate through the folders to find the "Terrain" subfolders.
• Download the specific files you need. If more than one file is available, use the metadata input file description to locate the specific terrain file that was used for a specific simulation.

Accessing Flood Output Mapping Files

LWI consultants created flood output raster files to make model results more accessible. These have been uploaded in dedicated subfolders with each HEC-RAS calibration/validation and design storm model.

To download flood output mapping files only:

• Locate the desired model application and open its metadata page.
• Scroll to the bottom of the page to access the model files.
• Navigate through the folders to find the "FloodOutputRaster" and/or "OutputRaster" subfolders.
• Download the specific files you need.

In some cases, output from related models (e.g., sub-basins of a watershed) were mosaicked together, and the resulting output rasters were uploaded as a separate dataset instead of with the model application. If that is the case for the model application of your interest, follow these steps:

• Locate the desired model application and open its metadata page.
• Scroll to the bottom of the page and find the link to the "containing package". Click on "See more" to open the metadata package that includes the model of your interest.
• In the package metadata, locate the Dataset metadata and click on it to open it
• At the bottom of the dataset metadata page, you will find the raster files that were uploaded.
• Download the specific files you need.

Maximum water depth and water surface elevation are available for all produced sets of rasters. Many consultants also included maximum velocity.

Flood Output Rasters file name follows a specific naming convention to help users understand their content. The naming convention for past and future generation of H&H and Consequence Models and Data can be found here.
