Transcript of San Joaquin River Water Quality Modeling- A Beginning
San Joaquin River Water Quality Modeling- A Beginning
SJR-DO TMDL Technical Work Group Presentation Russ Brown- Jones & StokesJanuary 20, 2005
San Joaquin River Data Atlas-modeling without data is folly
Initially Part of the DWSC and SJR WQ Modeling Contract with HydroQual (and Jones & Stokes)
Upstream Modeling Task will Update (2004+) and Expand (missing data sources)
Includes 1984-2003 (20 years) of daily/grabsAnnual Master Excel FilesComparison Files with Basic Annul Graphs and
simple calculations
Data retrieval can be hard work –with some spinning of wheels
San Joaquin River Flows & EC-daily water and salt budgets
