Hey all,

 

I am trying to get some ideas for a river flow map. The end goal would be to show the CFS (cubic feet per second) levels during spring runoff and during normal summer levels. I would like to show this with one map and not two.  I have a couple of ideas on displaying this data but I was curious if any of you have better ideas or recommendations on making this map? I have thought of showing this with a bar scale but I'm not sure if that would be the best tool. Come on Carto world and give me some ideas.

 

 

Thank you for the help

 

 

cheers

What are your ideas so far? Got a mock up we can check out? :-)

The Atls of Oregon has a great map of river flow where they taper river sections by thier stream flow values. I'd follow this example but overlay the summer (presumably less flow) right on top of the spring flows. Use a different color and perhaps a multiply trasnparency (if in Illsutrator).

Thanks for the input! Sorry, no mock ups yet. I was thinking about doing a type of proportional symbol map to display the two different data sets. Bare with me as I am still a "young grasshopper" with all of this GIS stuff.

 

 

cheers

Another idea to think about that is somewhat similar to the good one David pointed out, is to classify the change between spring and summer and use color to represent the delta similar to the map below we made for transportation volumes within a 45 minute drive from downtown Bend.  

 

The road volumes are symbolized by stroke width and the change between 1998 and 2004 are represented by color.  Traffic volumes and cfs are not that similar, but it's another way to illustrate a few different volume variables using line segments.

Thanks katzmoye!  Heath Brackett updated the data and added some polish on later versions - but it't the Cascadian terrain (via NLCD landcover) that I really like.  Maybe I should add the names of the volcanoes and make placemats.  :lol:
