Too Much and Not enough precision with prj2wepp provided files #79

Closed akrherz closed 4 years ago

akrherz commented 4 years ago

Oye, great gnashing of teeth today. Found two fun things.

  1. When prj2wepp merges up the profile, soil, and management breaks, it needs enough decimal precision with the down-the-profile faction to rectify the value to the same point! It appears providing full decimal precision to the value will make the magic happen.
  2. The flowpath2prj.py has a very small non-zero slope default of 0.00001, this is too small for WEPP it appears, so lets go down to 1cm/3m, which is about 0.003, or 0.3%

Implemented a fix and verified that it is working properly, closing.
