Reducing Scour in SRH-2D Sediment Transport

Do you have an SRH-2D sediment transport model that has an unreasonable amount of scouring? There could be several different issues in your model that are causing unreasonable scouring, however, SMS contains several different ways to fix this issue. This article will cover how to limit scouring so it is put to extremes in your model.

  1. Review the sediment loading on your boundary conditions for the sediment transport model. Double-click on one of your boundaries to check your sediment boundary conditions to review how the sediment loading has been defined. In the SRH-2D Assign BC dialog check and update the Sediment inflow section if needed.

  3. For your sediment transport SRH-2D simulation, go to SRH-2D Model Control and select the Sediment tab. Review the Particle diameter threshold section to make certain that the sizes are reasonable. Often having diameters that are too large causes scouring.

  4. Another place to review is the SRh-2D sediment material coverage. Right-click on the click Materials List and Properties. Under Gradation Curve, right-click on one of the materials and select click Edit Curve to bring up the Gradation Curve dialog. Review the gradation values and check for inconsistencies. Remember that the values need to be scaled from the smallest sand to the largest boulder. It is important to remember that the maximum number of functioning rows only goes up to nine. Any more than this will cause inconsistencies to appear.

    When the values that are entered in the Sediment Gradation Parameters are put to extreme values this is what will often cause the deep scour you may see in your model. A regular model will be smooth with very little deviation. A helpful resource to use if things are still not clear is the USBR website. They have example problems that you can follow.

These are just some of the tips for reducing scouring in your SRH-2D sediment transport models. For additional support for sediment transport with SRH-2D contact our technical support team. Try out SRH-2D with sediment transport in SMS 13.2 today!

Tips for Organizing the Project Explorer in SMS

SMS has many kinds of datasets, geometries, and simulations that could be added to your Project Explorer. These are useful features with essential roles in building a valuable project in SMS. But sometimes the Project Explorer gets very full and becomes difficult to navigate. This is when it can be useful to organize the Project Explorer to make things easier for you and those you work with. Today, we have some tips on how you might keep things organized so you can accomplish what you need to.

Example of Project Explorer Organization in SMS
  1. You might find it useful to name each new project element with a name that helps describe it. Descriptive names can help you find your project elements more quickly when you need to tweak something here or there. For example, you might have a materials coverage where the default Manning’s n is 0.015 and another one where you’ve changed it to 0.045. Labeling the materials coverage “n-0.015” and “n-0.045” could help you remember the difference between the coverages.
  2. You can add folders to organize items in the Project Explorer. For instance, you could group coverages according to which simulation you intend on using them for. Or maybe you have already imported a couple of rasters that you only need for one element of your project. You could put them together in a folder and collapse the folder in the Project Explorer. This will keep them out of sight while you don’t need them and could help you find them faster once you do need them. Note that solution data is automatically organized in folders in coordination with each simulation in the project.
  3. You can add notes to most elements of your project. To add a note, use the Properties… right-click command on an item in the Project Explorer and go to the Notes tab. There, you can leave notes for your colleagues (or yourself) about the item’s intended use or provide additional information that is not readily apparent. This is particularly helpful with simulations when you can add a note giving a summary of the key features of that simulation. Notes could also be used to indicate datasets you compared to get a new dataset. These can help everyone keep track of what function each thing serves in a given project.
  4. As you go through the project, it is recommended to delete what you’re not using. Not only does this organize the Project Explorer, it also frees up space in SMS. This can help you avoid slow processing time that can come from too many simulations. In general, we recommend you not have more than seven simulations in a project. It is also recommended to remove large rasters, shapefiles, or images after you are done using them. If you want to keep certain elements that you’re not using right now, you may want to minimize them or put them in a folder when not in use.

Using these tips, you will keep your projects organized and accessible. Make use of the organization tools for the Project Explorer in SMS today!.

Introducing the Toolbox in SMS 13.2

One of the new features added to SMS 13.2 is the Toolbox. The addition of the Toolbox allows multiple tools to be collected into one location. Many of these tools previously existed in other locations in SMS such as the Dataset Toolbox. In addition to these tools new tools have been developed for the Toolbox.

You can access the Toolbox using the Toolbox macro button located on the macro toolbar. Clicking the macro will open the Toolbox dialog containing a list of available tools.

The tools have been organized into folders in the Tools tab. Examples of folders include: Coverages, Datasets, Rasters, and Unstructured Grids.

  • Coverage tools are used to manipulate coverages and feature objects.
  • Datasets tools are many of the tools that have previously existed in the Dataset Toolbox and are used to manipulate datasets.
  • Rasters and Lidar tools are used to adjust and clean up raster and lidar data.
  • Unstructured Grid tools can manipulate and adjust unstructured grids (UGrids).
Example Compare Dataset Tool in the Toolbox for SMS 13.2

In addition, there will be folders for manipulating data related to specific numeric models. For example, there is a folder with tools that work with ADCIRC data.

The Toolbox also contains a History tab. This tab keeps a record of all the tool runs used with your projects. As a result, it allows you to run the same tool again using the same settings. For example, you might use the Compare Dataset tool to compare the solution sets from two different simulations, then discover that there was an issue in one of the simulations. After you fixed the simulation and ran it again, you could use the history feature of the toolbox to run the Compare Dataset tool using the same settings as before.

The History tab also shows if a tool executed successfully or not. Furthermore, it lets you make notes on the different tool runs, allowing you to clarify why a tool run failed or what you were hoping to accomplish with a particular tool. This can facilitate collaborating with colleagues when working on the same project.

Additional tools will be added to the Toolbox in future versions of SMS. Try out the Toolbox in SMS 13.2 beta today!

Announcing SMS 13.2 Beta

We are pleased to announce that SMS 13.2 has been released in beta. SMS 13.2 beta includes many new features to aid in your surface-water projects. Here are a few of the new features we’re excited about.

SRH-2D Improvements

SMS continues to add support for SRH-2D. SMS 13.2 has improved support for modeling HY-8 structures as links to allow for 2D flow overground.The sediment transport options have also been improved. Additional tools for SRH-2D include calibration options and report generation.

New Toolbox

A new toolbox has been added giving you more options for adjusting and manipulating data in your projects. The toolbox contains many of the tools that are in the Dataset Toolbox with the addition of several more tools. Additional tools will be added to this toolbox in future versions of SMS.

Example of the Toolbox in SMS 13.2
Display Themes

The Display themes tool allows you to save your display options settings which can be reused later or applied to other models. Specific display options and views can be saved as display themes. Furthermore, you can have multiple display themes in a project. This makes it easier to switch between different regularly used displays.

UGrid Clipping

SMS continues to improve its features for unstructured grids (UGrid). The UGrid module now has an additional option for clipping. This option can be found in the UGrid Display Options. Turning on the UGrid clipping option allows you to create a "clipping widget" that you can use to hide part of your Ugrid. Primarily this feature allows you to view cross sections of a UGrid.

Model Interface Updates

The interface for a couple models have been updated. This includes CMS-Wave and TUFLOW-FV. These interface updates make use of workflows similar to CMS-Flow and SRH-2D. Additional functionality has also been added to these models.

These are just a few of the features that are a part of SMS 13.2 beta. Try out these features and many more by downloading the SMS 13.2 Beta today!
