  1. Water Resources Database(WRDB) Steven Davie Tetra Tech Inc. Chris Wilson Clayton Engineering

  2. History of WRDB • Developed by Dr. Chris Wilson at Clayton Engineering, Inc. • Database developed to support a large data collection effort and model development. • 1994, database to support Dr. Roy Burke at GAEPD on the Chattahoochee River Modeling Project. • Since 1994, numerous enhancements to support large state-wide datasets, model calibrations, and TMDL development. • Currently supporting version 4.4. • www.WRDB.com

  3. Purpose of WRDB • Developed to store water resources data. • Archival and transfer of data and modeling projects. • Allow for tracking (QA/QC) of all data. • Perform data analysis functions: • Summary statistics (7Q10 low flows, percentiles, etc) • Graphing (histograms, time series, longitudinal) • Water quality assessments (impairments) • Common database structure for data from various sources. • Use and/or export data for model calibration.

  4. Database Concepts • Why use a Database? • Why use a Relational Database? • Tables, Fields, and Records • Data Management • Storage • Retrieval • Analysis • Presentation

  5. WRDB Support Files • Stations • Station Groups • Branches • Parameter Codes (PCodes) • Parameter Code Groups • Compositing Codes (CCodes) • Database Batch Tracking • Quality Codes (QCodes)

  6. Demo: WRDB User Interface 1. The WRDB Interface • WRDB Functionality and Tools • Case Study – Flint Creek AL

  7. Location Maps

  8. Location Map

  9. Location of Stations in WRDB

  10. Recent Updates • High flow calculation for sediment transport (Q1.5). • Pollutant Loading Curve. • Enhanced Import Capabilities. • Import LSPC (watershed) model files. • Enhanced Graph package. • New versions will be posted on the Toolbox and WRDB websites.
