I like looking at maps that isolate different natural features. And I think that rivers make pretty patterns. So I made a series of scripts that generates a pretty map of rivers. I hope to print the maps of places that are important to me as art.

The code that generates these maps is here: https://git.dendroalsia.net/ben/pretty_rivers
|
||||
|
||||
|
||||
One key to making the map visually appealing, is setting the width of the river relative to the upstream watershed area. The USGS data includes that watershed area, and through trying different options, I found that this ratio worked well:
|
||||
|
||||
linewidth = (upstream surface area)^0.3204*0.0446
|
||||
|
||||
This works for the extent and river sizes in Wisconsin, I have to adjust it for maps of smaller areas or different sized rivers.

I'm interested in rivers (both ecologically and recreationally) and I want to know water level they are currently at, and how does that compare to their water levels throughout the year and in their recent history.
|
||||
In the US, the United States Geologic Survey (USGS) maintains a large set of realtime water level sensors, and that dataset is queriable through an API. So I wrote these scripts that take a set of rivers and their associated gauge IDs, downloads the recent and historical data and generates a bunch of graphs.
