FOR MAP LAYOUT TO BE TURNED IN

Create an 8.5" x 11" layout clearly deliniating delineating the subbasin and watersheds on top of a basemap, with the symbology and labels corresponding to the watersheds. You may need to further adjust the order of your layers in the Contents pane and their symbology.

...

Next, you will add flowlines to your map, which were previously downloaded from NFIE.

1. At the top left of your Layout view, click the Lab1 map tab to return to your map view.

2. In the Contents pane, check the Flowline and Catchment layers to make them visible.

...

Now you would like to select out only the flowlines and catchments within the Buffalo-San Jacinto subbasin, but this is not possible with an attribute query, so you will instead use a spatial query.

1. On the ribbon, click the Map tab.
2. In the Selection group, click the Select By Location button Main menu, select Select By Location….
3. For ‘Input Feature Layer’Features’, use the drop-down menu to select Flowline.

2. Remove the original Flowline layer from the Contents pane.
3. Repeat step 1-7 using Catchment layer as Input Feature Layer and name the new feature class “Catchments”.
4. Uncheck the Catchments layer, so it is no longer visible.
5. In the Contents pane, click the line symbol beneath the Flowlines layer name.

Symbolizing features using a single symbol

...

Add a text box to the layout containing the answers to the following questions:1)     

1. How many catchments are there in the Buffalo-San Jacinto subbasin?

...

1. What is their average area in acres and in km²?(Look up conversion factor.)

...

1. What is the total area of catchments in km²?

...

1. What is the ratio of the total length of the streamlines to the total area of the Buffalo-San Jacinto catchments (called the drainage density) in km^-1?
