Model water quality using historic data and CSO events and give indicators of acceptaple uses. #11

Using CSO events, precipitation, and flow rates and other water data, model the historic measures of water quality (#10). Use this model to nowcast current water conditions.

Based on current predictions and water standards #9, indicate what parts of the river are okay for swimming, canoeing, and non-contact boating.

@andreweskeclarke, @derekeder, @evz, @jpvelez, @sbeslow I think that this makes sense as a possible end point.

Sounds good. Are we able to find out at what level of confidence the CPD forcasts beach quality (i.e. here http://www.cpdbeaches.com/beaches/Jarvis-Beach/)?

Started on a predictive model for fecal coliform in 6228e10a5af837704763f75c1f1837c4bd856980

The results look promising for our the possibility of building an predictively valid model:

Note, this model does not know about CSO events.

The predictors that I found through stepwise regression are in this csv

Next steps are to go through this csv, and figure out what the variables mean.

Commited some work in progress, may be of use for you. Have started combining rainfall and cso events for a single measurment point (WW_40, near the confluence of Bubbly Creek and the South fork of the Chicago River). a90fafa04f25833522665c9c5579c633691ddfb7

Hey @bsuman79, how's the modeling going?

didn't had much time to work on it since last week. Got side tracked with another project. -Suman
