Runoff

As our rainfall totals build, our creeks are filling.  Most of them are running bank full.  It looks like everything that is falling is running off.  I did some hydrological calculations for my county to see what is actually happening.  We have had around 3 inches of rain so far.  The calculations show that a 3.11 inch rain in 24 hours will produce 1.03 inches of runoff from an acre of land with 2% slopes.  The storm listing is idealized, but it gives some idea of what is going on.  We should have added 2 inches of water to our subsoil at this point.  More is on the way, and even though we will likely have flooding, we will still be adding to soil moisture as well.

  1. Yup, those are definitely some of the challenges of winter time! Hopefully, there are things like inlet filters put in place to help combat the runoff!
