i-Tree Hydro concentration problem

Post by yobunker » Tue Nov 15, 2011 1:39 pm

The instant TP concentration calculated from water quality report is about 1000X smaller than EMC data mentioned in the user manual. As I have no access to code, I could only guess that there might be a unit calculation problem in the i-Tree hydro. Could anyone help me regarding this problem?

----------------------
Here is an example (1 row data) from my report:

Date/Time
01/05/2005 08:00:00

Total Runoff (m³/hr)
2.4685475988

Poll TP Median (kg)
0.00000042564

Calculated TP Conc. (mg/L)
0.000172425

i-Tree Hydro concentration unit issue

The Water Pollution Reports table column are displaying values in g/hr and not kg as indicated in Hydro v4.0.3. In addition, Median & Mean values for some pollutants are reporting the same values and will be updated to report properly in the next upgrade. Thanks to Yobunker and the VT Team for helping to identify these issues.
