1. Begin with an existing MODFLOW 6 project.
The existing MODFLOW 6 model can be created using the conceptual model or grid based approach.
2. Create the Stream (SFR2) coverage and arcs.
While following the steps below to create a coverage, make sure to select the Stream (SFR2) option in the Coverage Setup dialog:
1. Create a new coverage with a Stream option turned on.
1. Create new coverage from scratch.
  1. Use the New Coverage right-click command.
  2. Use the Coverage Setup dialog to create a new coverage by selecting the desired coverage properties and naming the coverage.
2. Create new coverage from an existing coverage.
  1. Use the Duplicate command on an existing coverage. This will copy any feature objects on the coverage.
  2. Use the Rename command to give the coverage a new name.
  3. Change the coverage setup.
2. Create arcs defining the streams.
1. Create feature points, arcs, nodes and vertices.
In the map module, create feature objects in the active coverage.
  1. Use the Create Arc GMS Create Arc Tool.svg tool to create arcs in the map coverage.
  2. Begin creating a new arc by clicking in the graphics window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
  3. Double-click or press the Enter key to terminate the arc.
  4. Use the Create Point Create Points Tool.svg tool to create additional nodes alone or to split arcs.
2. Modify arcs.
Feature arcs, whether digitized or incorporated from a boundary condition or a material coverage, often need to be edited after initial creation.
1. Create additional vertices on arcs.
  1. Use the Create Vertex GMS Create Vertex.svg tool to add vertices along arcs.
2. Refine the arc shape.
  1. Use the Select Vertices GMS Select Vertex Tool.svg tool and the Select Points\Nodes GMS Select Node Tool.svg tool to move/edit existing arcs and refine the shape by dragging the nodes/vertices.
  2. Use the Select Arcs GMS Select Arc Tool.svg tool to move entire arcs .
3. Split arcs.
An existing arc can be split by:
1. Converting a vertex to a node.
  1. Use the Select Vertices GMS Select Vertex Tool.svg tool.
  2. Select the Feature Objects | Vertices → Nodes command to split the arc into two arcs.
2. Add a node to the arc.
  1. Use the Create Point Create Points Tool.svg tool to add a node on an arc in order to split it into two arcs.
3. Connect the end of an existing arc to the middle of the arc.
  1. Use the Select Points\Nodes GMS Select Node Tool.svg tool to drag the node of an existing arc to anywhere in the middle of another arc. This will split the second arc into two arcs.
4. Add a new connecting arc.
  1. Use the Create Arc GMS Create Arc Tool.svg tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
5. Split overlapping arcs using the Clean Options dialog.
  1. Select overlapping arcs using the Select Arcs GMS Select Arc Tool.svg tool.
  2. Use the Feature Objects | Clean command to bring up the Clean Options dialog.
  3. Select the Intersect selected arcs option (for selected arcs) or Intersect arcs option (for all overlapping arcs) to split the arcs.
4. Merge arcs.
Two arcs that share an end node can be merged together.
  1. Select the shared node using the Select Points\Nodes GMS Select Node Tool.svg tool.
  2. Click on the Feature Objects | Nodes → Vertices menu command to merge the arcs.
  3. If desired, the Select Vertices GMS Select Vertex Tool.svg tool can be used to select and delete the new vertex.
5. Transform arcs.
  1. Select the arc using the Select Arcs GMS Select Arc Tool.svg tool.
  2. Use the Edit | Transform command.
  3. Use the Transform dialog to scale, translate or rotate the arc.
3. Correct arc directions.
  1. If necessary, turn on Arc direction arrows in the Display Options dialog.
  2. Using the Select Arcs GMS Select Arc Tool.svg tool, right-click on arrows running the wrong direction and select Reverse Arc Direction.
3. Assign arc and node attributes.
1. Assign stream attributes to arcs.
  1. Using the Select Arcs GMS Select Arc Tool.svg tool, double-click on stream arcs.
  2. Enter stream arc attributes in the Attribute Table dialog.
2. Assign stream attributes to nodes.
  1. Using the Select Points/Nodes GMS Select Node Tool.svg tool, double-click on stream nodes.
  2. Enter stream node attributes in the Attribute Table dialog.
4. Add the SFR package to the simulation.
  1. Right-click on the MF6 GWF Model.svg GWF model and select New Package, then select the desired package from the list.
5. Map from coverage to the stream package.
  1. In the Project Explorer, right-click on the package and use the Map from Coverage command.
  2. Select the desired coverage from the Select Coverage dialog to map its data to the selected package.
6. Modify SFR inputs.
  1. Right-click on the package in the Project Explorer and select the Open command.
  2. Modify the inputs in the package dialog.
