How to Calculate Riprap Using the Hydraulic Toolbox

Are you needing to determine the size of stones needed for riprap? Having stones that are too small will reduce the effectiveness of the riprap which could be disastrous. On the other side, having stones that are too large could cause unnecessary expense.

After defining drainage data in WMS, it is possible to calculate the riprap needed for your model using the FHWA Hydraulic Toolbox. To do this:

  1. Define your drainage data in WMS.
  2. Assign each basin attribute to an analysis method by double-clicking on the feature, and then selecting Edit Attributes…. This will give you the opportunity to link your drainage data to the Hydraulic Toolbox.
  3. Click on the Hydraulic Toolbox macro in WMS to bring up the Hydraulic Toolbox.
  4. You can calculate riprap using one of two methods:
    • Channel Lining Design Analysis Tool. Keep in mind when using this tool that a filter material must be separately designed.
    • Riprap Analysis Tool. This tool will calculate the filter material along with riprap size.

Once in the Hydraulic Toolbox, locate the name of the analysis method chosen and double-click to open the analysis dialog for the chosen parameter and method. You will notice that all of the data you input into WMS is now filled in the analysis tool. After you specify blank parameters, the tool will calculate and display the results at the bottom of the screen under “Minimum Riprap Thickness”.

Using the Hydraulic Toolbox to calculate riprap can help your project move forward. The toolbox also contains many other features worth exploring. Try using the Hydraulic Toolbox today!

Quickly Delineating a Floodplain

How many watershed projects require knowing which areas are in a floodplain? There is a lot of debate over building on floodplains, but before that debate can happen, the location of the floodplain needs to be known.

A new feature in WMS makes this process quick and simple.

The Map Flood tool utilizes ground elevations and existing flood hazard maps from the Federal Emergency Management Agency (FEMA) to quickly visualize the impacts of possible modifications in the flood level. The tool is designed to utilize data from web services including ground elevations, flood hazard base flood elevations, and flood hazard floodplain extents.

The Map Flood tool is accessed by clicking on the Map Flood icon in the toolbar.

Running the tool will do the following:

  • Download elevation data for the area which is stored as a scatter set
  • Download base flood elevation lines for the area which is stored as a map coverage
  • Download a flood extents polygon which is stored as a map coverage
  • Download a flood insurance map as a image in the GIS module
  • Create a water surface elevation for the base flood
  • Create an offset water surface elevation for the modified flood level
  • Compute a new flood extent polygon for modified flood level

For locations that do not have FEMA data, you can use your own data to generate flood extents. As long as a ground elevation dataset and a water surface elevation have been imported into a WMS project, then the Map Flood tool can be used to create a fast floodplain. This data needs to be imported into WMS as either a 2D scatter set or a TIN.

Using the new Map Flood tool can greatly reduce the time it takes to delineate a floodplain. Try out the new Map Flood tool in WMS 11.0 today!

What We Learned at the 2018 Aquaveo User Conference

Aquaveo held its first annual User Conference from October 16-17, 2018! It was amazing to get to meet so many of our users at once. We hope everyone had a great time.

For us, it was exciting to meet users from all over the world. We met users from the United States, Canada, Portugal, Germany, the United Arab Emirates, Guyana, and Thailand. When asked why they came, the attendees said they came to learn:

  • How Aquaveo’s products can help with their projects
  • More of what Aquaveo has to offer
  • What Aquaveo is all about

In listening to what our users had to share with us, we took away a couple key items that you want to see improved in our software.

  1. You want modeling to go faster. We understand the demand to give results in less time is growing, so we will be looking at ways to make the process of modeling take less time and still be accurate. Some of the innovations added into Aquaveo’s software already significantly reduce the time it takes to complete a model. We hope to add more automation and tools to speed up modeling times.
  2. You need to be able to work with big data. More data is becoming available and you want to be able to use it. This means processing large files covering larger areas in more detail. At Aquaveo, we are working on doing this, including optimizing our code and adding new tools to work with large files such as lidar files.

We’d like to thank the following for participating in our user conference:

If you couldn’t make it to the Aquaveo User Conference this year, we will be having another one next year. Watch our website and Facebook page for future details. See you next year!

Performing a Silent Install of XMS

Are you an IT administrator needing to perform a silent install of GMS, SMS, or WMS in a classroom or office? Some classrooms and offices have multiple students or employees changing machines regularly. Non-administrator users are often unable to change the licensing password, lock, or server when these license settings are stored in the global area of the registry. Because of this, we changed the license settings so they are now stored in the user area of the registry. This means that each user account requires this to be setup.

This silent install (or quiet install) workaround requires each user to have the rights to modify the registry. If registry access is restricted, a network administrator can do this by opening the Group Policy Management Editor and creating a startup script that automatically runs the batch file whenever the computer is restarted.

Note: Editing the Registry in Windows is a very advanced administration step. Please always create a backup of the Registry before making changes.

It can be a burden have to manually update the network lock server address in HKEY_CURRENT_USER for each user on each computer. The silent install process is simplified by creating a Windows Registry file that contains the license information and a batch file that can be executed to insert the registry information and launch WMS. The batch file automatically updates the registry for the user and then opens the WMS application. This is the safest way to edit the registry key, as well. The batch file can then be placed on each computer that needs to be updated, and the individual users can execute it as needed.

This workaround uses WMS as an example. This information also applies to GMS and SMS. You can see an example of a registry file in step 1 and the batch file in step 2, below.

  1. Create a file, “Netenble.001.reg”, as follows, replacing "license" with the name or IP address of the network lock server. For example, if the network lock server was at 127.0.0.27, you would use “127.0.0.27”:
    Windows Registry Editor Version 5.00M
    [HKEY_CURRENT_USER\Software\EMRL\WMS]
    "Netenble.001"="license"

    Note: This information was created using Windows 7. Because different Windows versions can have different REG file formats, we recommend you install WMS on one machine, register it to the correct network lock server, then export the [HKEY_CURRENT_USER\Software\EMRL\WMS] registry key. Open the registry file in the text editor and remove every line except those similar to those shown in the image above, and save the file as “Netenble.001.reg”.
  2. Create a file, “wms11.bat”, that will update the registry and start WMS: reg import Netenble.001.reg
    wms.exe
  3. Place these two files in the WMS folder in the image that will be distributed to the affected computers. For example, for the 64-bit version of WMS 11.0, the default location for the folder is “C:\Program Files\WMS 11.0 64-bit\”.
  4. Create a desktop shortcut to the batch file for the convenience of the user. If doing this via a startup script in the Group Policy Management Editor, this step can be skipped.

This silent install workaround can save you significant time as a network administrator. Try it out today!
