This tutorial builds on the the previous tutorial, [[Tutorials:12_Groundwater | Tutorial 12: Groundwater]].  <br>

If you are starting at this tutorial, 

<ol>
	<li>In the 2D Grid Module [[Image:Icon_2DGrid.png]] select '''GSSHA™ | Open Project File.'''</li>
	<li>Browse to the Sediments folder.</li>
	<li>Select the EauGalleGSSHASed.prj file and select Open.</li><br>
</ol>

This is a GSSHA™ model of the Eight Mile Run basin in the Eau Galle River watershed in Wisconsin.  This is a long-term model with groundwater parameters included.

==Adding Soil Erosion==
<ol>
       <li>In the 2D Grid Module [[Image:Icon_2DGrid.png]] select '''GSSHA™ | Job Control...'''</li>
       <li>Click on the ''Soil erosion'' box</li>
</ol><br>

==Adding Sediment==

<ol>       
        <li>Click the ''Edit parameter...'' button next to the soil erosion spreadsheet option</li>
        <li>Make sure the ''Transport capacity'' is set to ''Kilinc-Richardson''</li>
        <li>Click the ''Add'' button three times to add three Sediments</li>
        <li>Fill in the Sediments spreadsheet with values from the following table:</li><br>

<div class="mleft">
{{Tutorials:Table15}}
</div><br>

        <li>Click ''OK'' to close the Overland soil erosion dialog</li>
        <li>Click the ''Edit Parameters...'' button in the Channel routing computation scheme portion of the Job Control dialog (top right corner).</li>
        <li>Make sure the Sediment porosity is set to '''0.4''', the Water temperature at '''20.0''' deg C, and the Sand size at '''0.25''' mm.</li>
        <li>Leave all other values at their defaults and click OK to close the GSSHA™ Channel Routing Parameters dialog</li>
        <li>Click ''OK'' to close the GSSHA™ Job Control dialog</li>
</ol><br>
        

==Specifying Soil Erosion Parameters==

<ol>
	<li>In the 2D Grid Module [[Image:Icon_2DGrid.png]] select '''GSSHA™ | Map Tables...'''</li>
	<li>Click on the ''Soil Erosion'' tab.</li>
        <li>In the ''Using index map'' combo box, select the ''Combined'' index map</li>
        <li>Click ''Generate IDs''</li>
        <li>Fill in the spreadsheet with values from the following table:</li><br>
        
<div class="mleft">
{{Tutorials:Table14}}
</div><br>

        <li>Click ''Done'' to close the GSSHA™ Map Table Editor</li>
</ol><br>

==Saving and Running the Model==

<ol>
        <li>In the 2D Grid Module [[Image:Icon_2DGrid.png]] select '''GSSHA™ | Save Project File...'''</li>
        <li>Change the project name to EauGalleGSSHASed1.prj and click ''Save''</li>
        <li>In the 2D Grid Module [[Image:Icon_2DGrid.png]] select '''GSSHA™ | Run GSSHA™...'''</li>
        <li>Toggle on the option to suppress screen printing and click ''OK''</li>
        <li>Once the model is done running, make sure ''Read solution on exit'' is toggled on and click ''Close''.</li><br>
</ol>

==Post-Processing==

<ol>       

        <li>In the Project Explorer, right-click on the Outlet Sedograph, located below the GSSHA™ solution folder (the folder with the letter "S" on it)</li>
        <li>Select View Graph...
        <li>The plot window should show the sedograph, which should look similar to Figure 39.</li><br>

[[Image:Sedograph.jpg|thumb|800px|center|Figure 39. Eau Galle Groundwater/Sediment Model Outflow Sedograph.]] <br>

        <li>Close the sedograph plot.</li><br>

If you wish to view more sediment related output, go into the GSSHA™ Job Control, click on Output Control, and toggle on any datasets you would like GSSHA™ to output.  Then save your project and run it again.

This concludes the GSSHA™ Sediment tutorial.
