Launch FLDWAV, FLDVIEW, and FLDXS applications from FLDAT
Calibration Analysis - Provide volume checks on flow data within the model - Analyze invert profile to determine potential problems with shallow depths - Automate as much of the “Procedures” document as possible - Interactively update Manning n values, rerun FLDWAV and review results
Time Series Analysis - Extract time series needed for calibration from various sources, display graphically, and write in FLDWAV or DATACARD format - Create time series at river confluences - Convert reservoir pool levels to msl - Compute missing time series values - Combine time series - Generate interpolated time series (e.g. generate 1-hr t.s. from 6-hr t.s.) - Check time series data for accuracy
